Answer:
It is elastic potential energy
Explanation:
Elastic potential energy is stored energy that results from applying a force to deform an elastic object. The energy is stored until the force is removed and the elastic object returns to its original shape, doing work in the process. Deformation may involve compressing, stretching, or twisting the object. Many objects are specifically designed to store elastic potential energy, for example:
The spring of a winding watch.
Given: Mass m = 45 Kg: Density ρ = 2.7 Kg/m³
Required: Volume V = ?
Formula: ρ = m/V
V = m/ρ
V = 45 Kg/2.7 Kg/m³
V = 16.67 m³
It is medium loud because very loud is called forte.
mezzo means medium. forte means loud. mezzo forte means medium loud.
answer: d) medium loud
Answer: catching the ball is a better choice.
Explanation:
The collision of 2 objects involves involves large impact force since the force is inversely proportional to the time in which the momentum of the object changes.
Mathematically
If we catch the ball we increase the time in which the momentum of the ball is decreased thus the impact force that acts on us is lower as larger time is allowed for the ball to decrease it's momentum.
If we allow the ball to hit us the momentum of the ball changes in a short period of time thus applying a large impact force on our body thus increasing the chances of toppling.
<span>The force will be zero if the wagons are moving at a constant speed (i.e. not accelerating), as there is no frictional force to overcome. If the wagons are accelerating, the force will be proportional to the acceleration, and 20% of the force applied by A.</span>
