What would happen if everyone on earth screamed at the same time?.
Answer:
There would be a huge sound like an applause. At 200 decibels (the loudest possible sound ever created on Earth), it could shatter ear drums.
Explanation:
Hope this helps
If everyone on the planet screamed at the same moment, it would be a tremendously loud and chaotic event.
The particular impacts and repercussions, however, would be dependent on a variety of parameters such as the strength of the screams, the length, and the location of persons.
The cumulative cries of billions of individuals would produce a deafening loudness, perhaps reaching levels far beyond what the human ear can handle.
Thus, those in close proximity to people yelling may experience discomfort, confusion, and even bodily pain as a result of the loudness.

A steel wire 0.72 m long has a mass of 5 x 10⁻³ kg. If the wire is under a tension of 60N, what is the speed of the transverse waves on the wire?
Answer:
93m/s
Explanation:
Solution,
Here,
Length(l)=0.72m
Mass(m)=5x 10⁻³
T=60N
As we have
v=√T/μ
And
μ=m/l
μ=5 x 10⁻³ /0.72
Now
v=√60×0.72/5 x 10⁻³
v=√8640
v=92.95m/s=93m/s

Kinetic Energy
Explanation:
Ang prinsipyo ay nagsasaad na ang enerhiya ay hindi maaaring malikha o masira, ngunit maaari lamang ma-convert mula sa isang anyo patungo sa isa pa. Ang tubig sa tuktok ng napakataas na talon ay nagtataglay ng gravitational potential energy. Habang bumabagsak ang tubig, ang enerhiya na ito ay na-convert sa kinetic energy, na nagreresulta sa isang daloy sa isang mataas na bilis.
A 60w bulb has a higher resistance than a 100w bulb, since the power rating is given assuming that the bulb is connected to a 120v source by itself. If you connect a 60w bulb and a 100w bulb in series to an outlet, which will shine brighter?.
Voltage drop across any components in series is proportional to its resistance. 60W bulb has higher resistance than 100W bulb if both the bulbs were rated for same voltage. So higher voltage drop will be across a 60W bulb.
In parallel voltage drops will be same across both the bulbs but current through it will be inversely proportional to the resistance. So 100W bulb draws more current than 60W bulbs.
60W dissipates more energy than 100W bulbs when in series and 100W bulbs dissipates more energy when in parallel.

Consider a resistor (R=1000 kΩ) and a capacitor (C=1μF) connected in series. This configuration is connected in series to a battery with an emf of 10 V.
After the capacitor is charged to its maximum value, the capacitor and resistor are disconnected from the battery and from each other. Then they are connected in parallel, so that the capacitor discharges through the resistor. How long will it take for the voltage across the capacitor to drop to 2.50 V?
Answer:
The maximum pressure is 10 V from across condenser.The highest charge mostly on condenser.
Vc = 10 x 1mf
= 10 ^ - 5C
The time it takes for the condenser to be 5 V different.
Thus we have, 0.69 x 10 ^ - 3 seconds.

Answer:
Excess currency after a series of deals or fees.
Explanation:
Let's put profit in perspective by using an example. For example, let's say you spend 72 dollars to build a certain product, then you sell that same product to your friend for 116 dollars. It costed 72 dollars to build that product and you sold it for 116, after subtracting the costs for building the product the excess currency is what you would call profit. Profit is your overall goal when running a business, you want to sell a product and make profit from it.

Object W has a surface area of 4. 5 cm2, Object X has a surface area of 2. 5 cm2, Object Y has a surface area of 6. 2 cm2, and Object Z has a surface area of 3 cm2. Which object would experience the most fluid friction? W X Y Z.
Answer: the most affected object by friction is the Y
Explanation:
The fluid friction consists of 2 parts.
viscous resistance and friction with air.
assuming that the objects are in contact with the air, the situation is described by the following equation.
with: C= numerical drag coefficient
p= density
A= Area of the object
v= velocity
so assuming the other variables are constants the area of the object is directly proportional to the fluid friction
What is the kinetic energy of a 1.000 g bullet traveling at 1,000 m/s?
Answer: B
Explanation:
The conventional units for Joules is defined with kilograms. We are given the mass of the bullet in grams. Using the conversion factor of 1kg = 1000g, we get that:
[tex]1g*\frac{1kg}{1000g} =1*10^-^3kg[/tex]
Kinetic energy is defined to be:
[tex]KE=\frac{1}{2} mv^2[/tex]
[tex]KE=\frac{1}{2} (10^-^3kg)(1000m/s)^2[/tex]
[tex]KE=500J=5*10^2J[/tex]
A sound wave has a frequency of 695 Hz in air
and a wavelength of 0.49 m.
What is the temperature of the air?
Relate the speed of sound in air to temperature in units of Kelvin, but answer in units
of Celsius.
Assume the velocity of sound at 0 ◦C is
332 m/s.
Answer in units of degC
This question involves the concepts of the speed of sound, frequency, and temperature.
The temperature of the air is "14.24 °C".
Temperature of AirFirst, we find the speed of sound at the given temperature:
v = fλ
where,
v = speed of sound = ?f = frequency = 695 Hzλ = wavelength = 0.49 mTherefore,
v = (695 Hz)(0.49 m)
v = 340.55 m/s
Now, the relationship between the speed of sound and temperature can be given by the following formula:
[tex]\frac{v}{v_o} = \sqrt{\frac{T}{273\ k}}\\\\T = (273\ k)(\frac{v}{v_o})^2\\\\[/tex]
where,
T = Temperature = ?v = speed of sound in air at given temperature = 340.55 m/sv₀ = speed of sound in air at 0°C = 332 m/sTherefore,
[tex]T = (273\ k)(\frac{340.55\ m/s}{332\ m/s})^2[/tex]
T = 287.24 k = (278.24 k -273) °C
T = 14.24 °C

shape of houses built in areas with hot climate and materials used
Answer:
Cement and sand will do
Explanation:
because without it you can't build
Answer:
Shape of houses built in areas with hot climate
Compact house forms, rather than sprawling, multi-wing designs work best in hot locales. Home designs with shaded porches, wrap around porches or plans with courtyards that create a shaded open area within the building are ideal.
How do you build a house in hot climates?
Place courtyards centrally to enhance cooling and ventilation. ...
Choose the right materials. ...
Use waterbodies and landscaping effectively. ...
Shade terraces and outdoor spaces. ...
Create sheltered, barrier-free spaces for air circulation. ...
Extend roofs to protect the walls and windows from direct heat.
Materials used building in areas with hot climate
The most common materials used for building walls in the warm-humid regions are stones, and earth-based bricks.
Concrete, bricks, and tile have a high thermal mass due to the large amount of heat energy needed to change their temperatures. This makes concrete an ideal building material for climates that are hot during the day but cooler at night.

During a race, a horse's speed increases from 65 m/s to 73 m/s during the last 5.0 seconds of that race What was the rate of acceleration during this time?
Answer:
1.6m/s²
Explanation:
It was difficult to type the answer here
During a race, a horse's speed increases from 65 m/s to 73 m/s during the last 5.0 seconds of that race, 1.60 m/s² was the rate of acceleration during this time.
What do you mean by an acceleration ?The rate of change of velocity is defined as acceleration. Acceleration usually indicates that the speed is changing, but this is not always the case. When an object moves in a circular path at a constant speed, it is still accelerating because its velocity direction changes.
Acceleration occurs when the speed of an object increases or decreases, or when it changes direction. Acceleration, like velocity, has two types: average and instantaneous.
a = v - v₀ / t
Then, a = 73 × 65 / 5
a = 1.60 m/s²
Thus, 1.60 m/s² was the rate of acceleration during this time.

At 40 degrees is 25g of NaNO3 saturated or unsaturated?
I think unsaturated
because -
At 55°C, a saturated solution would contain 120 g of solute, NaNO3. (Notice, this point is exactly on the solute's curve). If, for example we mixed in 140 g of NaNO3 instead of 110 g of solute at 55°C, we would create a SUPER saturated solution, because we would be at a point ABOVE the solute's solubility curve.
