Answer:14.14 cm
Explanation:
Given
Spring Compression 
Potential energy Stored in spring
Suppose k is the spring constant of spring
Potential Energy of spring is given by 




for 100 J energy





Answer:
Mechanical Energy
Explanation:
The sum of kinetic energy and potential energy of an object is its total mechanical energy.
5.4 x 1014Hz
wavelength x frequency = the speed of light
Answer:
Explanation:
The forces exerted by each mass is best understood in terms of their momentum.
Momentum is a sort of compelling force or impulse. It is given as:
Momentum = mass x velocity
Let us consider the momentum of the balls;
Substance C;
Mass = 1kg
Velocity = 5m/s
Momentum of C = 1 x 5 = 5kgm/s
Substance D:
Mass = 100kg
Velocity = 5m/s
Momentum of D = 100kg x 5m/s = 500kgm/s
Body D has a higher momentum compared to Body C. This suggests that body D will exert a higher force than C when they collide.
The higher the momentum, the more the force of impact it has.
Answer:
Explanation:
It would actually be A. 30 , as each hour of ascension (i am not sure about the correct terminology) equals 15 .
