Answer:
Explanation:
A restoring force is created when a spring is either stretched or compressed.
Restoring force created by first spring = spring constant x contraction
= 35 x .23
= 8.05 N .
It will act towards the right .
Restoring force created by second spring = spring constant x extension
= 48 x .23
= 11.04 N .
It will also act towards the right .
Total force created due to contraction in the first spring and extension in the right spring = 8.05 +11.04 N
= 19.09 N .
Answer:
1: toward the normal
2:away from normal
3: red because the index of refraction ( the ratio of the speed of light in a vacuum to the speed of light in a material) is increased for the slower moving waves
Answer:
This is the equation for elastic potential energy, where U is potential energy, x is the displacement of the end of the spring, and k is the spring constant.
U = (1/2)kx^2
U = (1/2)(5.3)(3.62-2.60)^2
U = 2.75706 J
