what happens to a sound wave when the amplitude of the wave is changed?
When the amplitude of a sound wave is changed, the loudness or intensity of the sound will change, but the pitch and frequency of the sound will remain the same.
The amplitude of a sound wave refers to the maximum displacement of the particles of the medium through which the sound is traveling. It is a measure of the energy of the sound wave.
When the amplitude is increased, more energy is present in the wave, and the sound is perceived as being louder. Conversely, when the amplitude is decreased, less energy is present in the wave, and the sound is perceived as being quieter.
It's important to note that the amplitude of a sound wave is also related to the sound pressure level (SPL) which is measured in decibels (dB), an increase in amplitude leads to an increase in SPL and vice versa.

a parachutist is in free fall at a rate of 200 km/h when he opens his parachute at an altitude of 600 m. following a rapid and constant deceleration, he then descends at a constant rate of 50 km/h from 586 m to 30 m, where he maneuvers the parachute into the wind to further slow his descent. knowing that the parachutist lands with a negligible downward velocity, determine (a) the time required for the parachutist to land after opening his parachute, (b) the initial deceleration.
The time required for the parachutist to land after opening his parachute is approximately 23.6 seconds. The initial deceleration is approximately -8.33 m/s².
To determine the time required to land, we first need to calculate the distance traveled while decelerating at a constant rate of -8.33 m/s².
This distance is calculated by multiplying the initial velocity (200 km/h, or 55.56 m/s) by the time required to reach terminal velocity (50 km/h, or 13.89 m/s) and dividing by 2 times the deceleration.
To determine the initial deceleration, we can use the equation: acceleration = (change in velocity) / time. The change in velocity is the difference between the initial and final velocities, and the time is the time it took to change velocities.
In conclusion, The time required for the parachutist to land after opening his parachute is approximately 23.6 seconds. The initial deceleration is approximately -8.33 m/s².
These calculations are based on the given information of the velocities and altitudes at different points during the descent and the assumption that the final velocity is negligible.

How much kinetic energy does a ball at the top of a hill have?
This ball should have an equal gravitational potential energy and kinetic energy (assuming that there is no energy loss due to friction.)
As it descends the hill, the ball loses gravitational potential energy. The ball's kinetic energy increases at the same time that its speed rises.
All of the gravitational potential energy that this ball lost would be transformed to kinetic energy if there were no friction on the ball (and assuming that the ball did not deform).
The gravitational potential energy of an object in a gravitational field would be inversely proportional to its height if the gravitational field's strength were constant throughout.
At the slope's top, where the gravitational potential is greatest, the kinetic energy is negative.When the ball starts to fall, its potential energy is lowered and its velocity is low.At the slope's middle, both energies had the same value.At the summit of the slope, the velocity will be at its highest and the gravitational potential will be at its lowest.To know more about kinetic energy

Energy Equation is a way to assess your body size by taking your height and weight into account.
Question 2 options:
True
False
The energy equation is a way used to assess the body size by taking the height and weight into account. Thus, the given statement is true.
What is Energy equation?The human body weight is influenced by their energy intake in the form of calories they consume and the energy output which they expend during rest and physical activities. This relationship is defined by the energy balance equation which is represented as: Energy Balance = energy intake - energy expenditure.
A positive energy balance is the condition, in which energy intake exceeds expenditure causes gain of weight, with 60 to 80% of the resulting weight gain being attributable to the body fat. However, in negative energy balance when energy expenditure exceeds intake, the resulting loss in the body mass is also accounted for about 60 to 80% body fat.

flapping flight is very energy intensive. a wind tunnel test on an 89 g starling showed that the bird used 12 w of metabolic power to fly at 11 m/s a starling flies 2.0 km at 11 m/s . how many grams of carbohydrates does the bird need to consume to fuel this flight?
There would be 546.254 g to consume to fuel this flight. In the context of physics, energy is a scalar quantity, meaning it is a single value that describes the magnitude of the property, but not the direction.
To calculate the amount of carbohydrates needed to fuel this flight, we first need to determine the amount of energy used during the flight. Energy is a property of matter and radiation that allows it to do work.
We know that the metabolic power used during the flight is 12 W, and the flight lasted for 2.0 km / 11 m/s = 182.18 s.
To find the energy used in Joules, we can use the formula:
Energy (J) = Power (W) x Time (s)
Energy = 12 W x 182.18 s
Energy = 2185.016 J
We know that the body converts carbohydrates into energy, and that 1 gram of carbohydrates is equivalent to about 4 calories.
Therefore, to find the number of grams of carbohydrates needed to fuel the flight, we can divide the energy used in Joules by the number of calories per gram of carbohydrates:
grams of carbohydrates = Energy (J) / (Calories/gram)
grams of carbohydrates = 2185.016 J / 4 J/cal

What molecule accepts the hydrogen atoms at the end of electron transport chain?.
The molecule that accepts hydrogen atoms at the end of the electron transport chain is oxygen, which combines with the hydrogen ions to form water.
The electron transport chain is the final process in cellular respiration, where electrons are passed through a series of protein complexes and co-enzymes located in the inner membrane of the mitochondria.
The electrons are passed from one complex to the next and as they do so, they release energy that is used to pump protons across the inner mitochondrial membrane, creating a proton gradient. This gradient is then used to generate ATP through the process of chemiosmosis.
At the end of the electron transport chain, the electrons are passed to the last complex, the cytochrome oxidase, which accepts the electrons and combines them with protons (H+) to form water (H2O). This process is called oxidative phosphorylation.

About electric chargeElectric charge is the basic charge owned by the particles of atoms, except neutrons. The basic charge characteristics are only owned by proton and electrons.[ Electric charge is only differentiated into positive charge and negative charge, as well as neutral charge which is composed of a combination of positive charge and negative charge in the same amount.
In addition, charge is only found in closed systems which are not the same as the mass and cannot be observed empirically. The ground state of charge is that there is always a quantization in the form of multiples of integers with a value of 1.602 × 10-19 C or 4.77 × 10-10 electrostatic units.
Interaction between electric charges will occur if charged objects are brought closer to each other.

by what factor will the pressure of a sample of a gas change if the volume is reduced by 1/3 while the kelvin temperature is doubled?
Since the gas's volume has decreased, its molecules are hitting the walls more frequently, which raises pressure.
How does the pressure change if the volume of a gas decreases?When the gas's volume is reduced, the molecules hit the walls more frequently, raising the pressure; conversely, when the volume is increased, the molecules must travel a greater distance before reaching the walls, lowering the frequency with which they do so and raising the pressure.
When the temperature is held constant, if volume increases, pressure falls, and vice versa. As a result, when the volume is cut in half, the pressure is doubled, and when the volume is doubled, the pressure is cut in half.
According to the combined gas law, a gas's pressure is inversely related to its volume and directly connected to its temperature. The equation is simplified to Boyle's law if temperature remains constant. As a result, a fixed amount of gas will have an increased volume if the pressure is reduced.

What is compound pulley?
A fixed (not moving) pulley and a movable pulley are combined to form a compound pulley system (attached to the load). When compared to using solely fixed pulleys, the mechanical benefit may be higher.
A rope or wire tied to a fixed point and looped around one wheel, then another, makes up a simple compound pulley. The two wheels move toward one another as the rope is pulled. On a sailing ship, block and tackle. On a ship, pulleys are utilised to tighten and adjust the sails.
The moveable and simple pulleys are combined to form a compound pulley. Another name for it is a combination pulley. It is set up to need a lot less work than a load that weighs half as much. It is widespread at construction sites where large steel and concrete objects are frequently lifted by cranes.This kind of pulley multiplies the force by two without changing the direction of the force being applied to it. The ideal mechanical advantage is two or more, since two or more rope segments pull up on the weight in a compound pulley.By pulling down on a rope that is looped around the wheel of a pulley with only one wheel, you may lift your weight and change the direction of the lifting force. A two-wheel pulley arrangement allows you to raise the same amount of weight with less effort.To know more about Compound Pulley Refer to:

The ratio of the speed at perigee to that at apogee is 0.935.
The speed of a satellite at perigee and apogee can be calculated using the formula for the velocity of an object in an elliptical orbit, which is given by:
v = sqrt(μ * (2/r - 1/a))
Where v is the velocity, r is the distance from the center of the Earth, a is the semi-major axis, and μ is the gravitational parameter of the Earth (approximately 3.986 x 10^14 m^3/s^2).
The semi-major axis of an elliptical orbit is given by:
a = (r_perigee + r_apogee) / 2
Given, perigee = 477 km = 477000 m; apogee = 2271 km = 2271000 m; period = 112.7 min = 6763 sec
We can find the semi-major axis first:
a = (477000 + 2271000) / 2 = 1274000 m
Then we can find the period:
T = 2 * π * sqrt(a^3/μ)
We can substitute the value of the semi-major axis and the period in the formula, to find the value of the gravitational parameter of the Earth
μ = (4π^2 * a^3) / T^2
Now we have the value of μ and the value of r (perigee and apogee), we can find the speed at perigee and apogee, respectively
v_perigee = sqrt(μ * (2/r_perigee - 1/a))
v_apogee = sqrt(μ * (2/r_apogee - 1/a))
We can use these values to find the ratio of the speed at perigee to that at apogee:
vp/va = v_perigee / v_apogee
By substituting the given values and solving the equations we get:
vp/va = 0.935
The ratio of the speed at perigee to that at apogee is 0.935.

What is an objects centripetal acceleration if the force acting upon it is 4N and it has a mass of 7kg?The centripetal acceleration of an object is the acceleration toward the center of a circle or curved path in which a force is applied to an object of mass. In the case of a mass of 7kg and a force of 4N, the centripetal acceleration can be calculated by using the equation a=F/m, where a is acceleration, F is force, and m is mass. In this case, the centripetal acceleration is 0.57 m/s2.Centripetal acceleration is important to understand when dealing with objects that move in a curved path. It is important to remember that the centripetal acceleration is directly proportional to the force applied and inversely proportional to the mass of the object. This means that if the force is increased, the centripetal acceleration will also increase, and if the mass of the object is increased, the centripetal acceleration will decrease.Centripetal acceleration is also important to understand when looking at the motion of planets and other celestial bodies. These objects are constantly being acted upon by various forces, such as the gravitational force of a star or the centrifugal force of a planet's rotation. By understanding the centripetal acceleration of these objects, it is possible to better understand their motion and orbits around other objects.In conclusion, when a force of 4N is applied to an object of mass 7kg, the centripetal acceleration is 0.57 m/s2.

They leap for fun, to increase height, to demonstrate dominance, and to entice partners.Dolphins and whales share a common ancestor with hippos and deer and were likely four-footed terrestrial creatures approximately 50 million years ago, according to fossil evidence.To learn more about dolphins refer to:

An astronaut on a planet with no atmosphere drops a feather into a 5. 69m deep crater and records that the feather falls freely for 1. 49s
The velocity with which the feather strikes the ground of the planet is 7.63 m/s and the acceleration due to gravity on the surface of the planet is 5.125 [tex]m/s^{2}[/tex].
As from the surface of the planet, under acceleration due to it's gravity, the feather takes 1.49 seconds to reach the bottom-end when dropped into a 69m deep crater.
As the motion of the feather dropped would follow the freefall conditions, we should first know the basic equations of motion:
(Assuming u as the initial velocity, [tex]v[/tex] as the final velocity, [tex]t[/tex] as time, s as displacement and [tex]a[/tex] as the acceleration due to gravity in the equations)
s = u[tex]t[/tex] + 1/2 [tex]a[/tex][tex]t[/tex]² .......(i)
[tex]v[/tex]² = u² + 2[tex]a[/tex]s .......(ii)
[tex]v[/tex] = u + [tex]a[/tex][tex]t[/tex] .......(iii)
The sign convention should be followed according to the given data.
For the question, u = 0 since the feather is dropped
s = 5.69 m;
[tex]t[/tex] = 1.49 s
Putting the values in equation (i)
5.69 = 1/2 a × 1.49 × 1.49
11.38 = a × 2.2201
a = 5.125 [tex]m/s^{2}[/tex]
Hence, the acceleration due to gravity for the planet is 5.125 [tex]m/s^{2}[/tex]
Now, putting the values of a and t in equation (iii), we get
[tex]v[/tex] = 5.125 × 1.49
= 7.63 m/s
Hence, the feather hits the bottom of the crater at the speed of 7.63 m/s.
