If a girl is sitting on box and the girl weighs 10kg and the box weighs 50 kg, how much force will be
needed to accelerate the box 5 m/s2? If the same force is used, what will the acceleration be if the girl hops off the box?
If a girl is sitting on box and the girl weighs 10kg and the box weighs 50 kg, 30.61 N force will be needed to accelerate the box 5 m/s2
Total weight = 10 + 50 = 60 kg
weight = mg
60 = m * 9.8
m = 6.122 kg
Force = ?
acceleration = 5 [tex]m/s^{2}[/tex]

a subway train is brought to a stop from a speed of 0.500 m/s in 0.400 m by a large spring bumper at the end of its track. what is the force constant of the spring?
The force constant k of the spring is 781000 N/m
What is force?
Once applied, force is described as an external cause that alters or tends to modify the state of the body; if the body is in motion, it comes to rest, and if at rest, it comes to motion. It can also induce a shift in the body's direction, shape, or size. Pushing or pulling a door with force is an example.
Because force is a vector quantity, it has both magnitude and direction. Newton's second law defines force as the "product of a body's mass and acceleration."
In physics, a force is an effect that can change the velocity of an object. A force can cause a mass object's velocity to change (e.g., moving from rest), causing it to accelerate. Force can be thought of as either a push or a pull. Because it has both magnitude and direction, force is a vector quantity. It is measured in newtons, the SI mass unit (N). The letter F stands for force (formerly P).
In its original form, Newton's second law states that the net force acting on an object is equal to the rate at which its momentum varies with time.
Here,
let the force constant is k
Using conservation of energy
0.50 * 5 *10^5 * 0.50^2 = 0.50 * k * 0.40^2
solving for k
k = 781000 N/m

The number of electrons transported is 8.1 x 10²² electrons.
The variety of electrons in a neutral atom is identical to the number of protons. The mass wide variety of the atom is the same as the sum of the range of protons and neutrons inside the nucleus. The number of neutrons is equal to the difference between the mass number of the atom and the atomic wide variety. The reduction half-response includes a -electron gain.
The LCM is consequently 6. The net equation is a six-electron transfer. The wide variety of electrons in an atom is identical to the atomic quantity of an element for neutrally charged species. this means the number of electrons and the number of protons in an element are identical. consequently, the variety of electrons in oxygen is 8.

After energy conversions, you end up with the same total amount of energy as the original amount energy. Which law explains this rule?.
The law that explains it is called the law of conservation of energy.
What does the law mean?The law of conservation of energy states that in an isolated system, the total energy remains constant, i.e., the total energy is conserved over time. Therefore, the initial energy of an isolated system is equal to the final energy of the system. As a result, energy can neither be destroyed nor created. Energy can only be transferred or transformed from one from to another.

what physical quantities do you need to measure to determine the electric power produced by a battery/power supply? what equation will you use?
Electrical power (P) can be defined as the sum of these two numbers if voltage (V) equals Joules per Coulombs (J/C) and amperes (I) = charge (coulombs) per second (A = Q/t). This is due to the fact that electrical power can also be expressed as P = V*I, or voltage times amperes.
Electric Power can be explained as:
Electric power is the rate at which electrical energy moves across an electric circuit. The SI unit of power is the watt, or one joule per second. The suffixes used to represent thousands, millions, and billions of watts are kilowatts, megawatts, and gigawatts, respectively. Watts are subject to the same standard suffixes as other SI units.

(b) if, instead, the cat had first prowled 72 m west and then 120 m north, how would this affect the displacement needed to bring it home? explain.
To find a solution, we first know about magnitude and displacement.
What is magnitude?
Magnitude typically refers to size or distance. By comparing the size and movement speed of the object, we can relate magnitude to movement. The object's or quantity's size determines its magnitude.
What is displacement?
A one-dimensional quantity called displacement (symbolized as d or s), also known as length or distance, represents the separation between two specified points. The meter is the SI's (International System of Units) accepted displacement unit.
Given that the beginning displacement is 120 meters to the north, the ultimate displacement is 72 meters to the west.
R = (A2+B2)1/2 is the magnitude of the resulting vector A+B.
The angle formed with the west direction is = tan-1(A /B) when = 139.9428m.
(Southeast) = 59.03624 degrees (B) Instead, if the cat had first wandered 120 m north, then 72 m west.
Then the magnitude of the resulting quantity is the same as R, but the angle is different because of = tan-1(72m / 120m) = 30.96375degrees.

you hear a loud noise at 900 hz and look up to see a bird diving toward you. you are able to identify the type of bird and you know that they usually make noise at around 800 hz. how fast is the bird moving?
When you hear a loud sounds at 900 Hz and look up to see a bird diving frequency you, the bird is moving at a speed of 38.12 meter's per second (m/s). Knowing the species of bird and that their frequency.
When this frequency range is overused, the result might be honky or nasal. The teacher from the Charlie B. series serves as this range's audio guide.
Auditory identification of birds can be done by birders who are familiar with the various bird speed. A keen birder might start looking for nearby birds of prey after hearing an alarm cry, whereas someone who hears speed a begging call would start looking for a nest that is well-hidden.

What is the relationship between generator and energy input
The relationship between the generator and the energy input is the fact that the generator uses mechanic energy as input to produce electricity.
What is an electrical generator device?An electrical generator device is any instrument capable of generating electrical activity using any source of energy as a source for such purpose, such as the movement (motion of mechanical energy) of a turbine.
Therefore, with this data, we can see that an electricity generator device is a given instrument used to generate electricity by exploiting the mechanical energy generated through a particular process.

a lighthouse is located on a small island 5 km away from the nearest point p on a straight shoreline and its light makes eight revolutions per minute. how fast (in km/min) is the beam of light moving along the shoreline when it is 1 km from p? (round your answer to one decimal place.)
The movement of the beam of light is an illustration of distance and rates
The beam of light along the shoreline is moving at 261.5 km per minute when it is 1 km from P
What is rate of change of distance?The ratio of the distance traveled to the time required is used to compute average speed, which is the rate at which distance changes in relation to time.
[tex]\frac{d\theta}{dt}[/tex] = 8 rev min⁻¹ = 16 [tex]\pi[/tex] rad min⁻¹
tan [tex]\theta[/tex] = [tex]\frac{x}{5}[/tex]
Differentiate both sides with respect to t
[tex]sec^2 (\theta) \frac{d\theta}{dt} = \frac{1}{5} \frac{dx}{dt}[/tex]
[tex]\frac{d\theta}{dt}[/tex] = 16 [tex]\pi[/tex]
Then,
[tex]\frac{dx}{dt}[/tex] = [tex]sec^2 (\theta) X 80\pi[/tex]
From the question, x = 1. calculate the hypotenuse (h) side of the triangle, using the following Pythagoras theorem.
[tex]h^2 = 1+ 5^2\\[/tex]
h =[tex]\sqrt{26}[/tex]
sec ([tex]\theta[/tex]) = [tex]\frac{\sqrt{26} }{5}[/tex]
Substitute sec ([tex]\theta[/tex]) = [tex]\frac{\sqrt{26} }{5}[/tex] in [tex]\frac{dx}{dt}[/tex] = [tex]sec^2 (\theta) X 80\pi[/tex].
[tex]\frac{dx}{dt} = (\frac{\sqrt{26} }{5} )^2 . 80\pi[/tex]
= 83.2 [tex]\pi[/tex] = 261.48
Hence, the beam of light along the shoreline is moving at 261.5 km per minute when it is 1 km from P.
