I= V/R
R= V/I these are the other two quantities
Answer:
7056 kJ
Explanation:
Given that,
Mass of a ship roller coaster is 36,000 kg.
It reaches a height of 20 m off the ground
We need to find the gravitational potential energy does it have. The formula for the gravitational potential energy ios given by :
E = mgh
g is acceleration due to gravity
E = 36,000 kg × 9.8 m/s² × 20 m
= 7056000 J
or
E = 7056 kJ
So, it will have 7056 kJ of gravitational potential energy.
Angle of incidence is the angle when the light strikes an object while angle of reflection is the angle produced when the light strikes off/reflects from the object.
The relation between these two is that both the angles are equal.
The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
Hope this helps!
