Answer:
Potential energy = 3635.8 Joules
Explanation:
Given that,
Weight lifted by a weight lifter is 12 kg
It lifts to a height of 1.75 m
We need to find the potential energy to the wights now have. The energy possessed by an object due to its position or height above ground is called potential energy. Its formula is given by :
P = mgh
g is the acceleration due to gravity
So, the potential energy is 3635.8 joules.
B. a prism.
This is because the term "angle of deviation" is used to describe the angle at which the light bends compared to the normal of the ray of light
Answer:
The H-R diagram can be used by scientists to roughly measure how far away a star cluster or galaxy is from Earth. This can be done by comparing the apparent magnitudes of the stars in the cluster to the absolute magnitudes of stars with known distances (or of model stars).
Ummm...my best answer is that heat helps the molecules move around faster and that temperature is the measure of that heat or cold.
