7 0

Answer: Energy cannot be <u>created</u> or <u>destroyed</u> just <u>changes</u> in form.

Explanation:

This is the principle of the first Law of Thermodynamics, which relates the work and the transferred energy exchanged in a system through the internal energy, which is neither created nor destroyed, it is only transformed.

In other words: The total energy of a system is always conserved.

How much force is required to accelerate a 57 kg skier 4 m/s2? ______ N (do not write anything except the number)
vfiekz [6]

The amount of force required to accelerate 57kg skier with an acceleration of 4m/s² is 228N.

<h3>How to calculate force?</h3>

Force is a physical quantity that denotes ability to push, pull, twist or accelerate a body and which has a direction and is measured in a unit dimensioned in mass × distance/time².

The force applied on an object can be calculated using the following formula:

Force = mass × acceleration

According to this question, a skier with mass 57kg accelerates at 4m/s². The force required can be calculated as follows:

Force = 57kg × 4m/s²

Force = 228N

Therefore, the amount of force required to accelerate 57kg skier with an acceleration of 4m/s² is 228N.

Which wave, A or B, has lower energy? A, because it has a higher amplitude B, because it has a higher amplitude A, because it ha
frutty [35]

Energy of wave depends on its amplitude and it is given as

E = \frac{1}{2} kA^2

here k = constant

A = amplitude

so energy will increase or decrease depends on the amplitude of the wave

So here if we need to check which wave has lower energy then we need to compare the amplitude.

If the amplitude is less then energy must be less

So please check in the figure that which wave out of A and B has lesser amplitude to find out the wave of lesser energy
