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.
The real place should theoretically have space for 87 passengers if it is an exact model and doesn't have modifications in the seat numbers.
It is true that a physical change occurs when a material changes shape or size, but the composition of the material does not change. The correct answer is True.
