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.

Answer:
the anwser is The healthy adult golden eagle, due to its impressive size and hunting prowess, has no natural predators. Eggs, chicks, immature eagles, and injured birds are susceptible to a range of predators, such as other birds of prey, including other kinds of eagles and hawks, bears, wolves and cougars.
Explanation:
Scientists use Silica to classify magma
Energy of wave depends on its amplitude and it is given as

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
