Answer:
Structure. Venus is in many ways similar to Earth in its structure. It has an iron core that is approximately 2,000 miles (3,200 kilometers) in radius. Above that is a mantle made of hot rock slowly churning due to the planet's interior heat.
Explanation:
Explanation:
Below is an attachment containing the solution.
Answer:
The magnitude of the total change in potential energy ΔU as the ball falls to the ground is 342 joules.
Explanation:
It is given that,
Height from which the ball is released, h = 8 m
Weight of the ball, F = 19 N
To find,
The magnitude of the total change in potential energy ΔU as the ball falls to the ground.
Solution,
The energy that is possessed by an object due to its position is called its potential energy. Its formula is given by :
So, the magnitude of the total change in potential energy ΔU as the ball falls to the ground is 342 joules. Hence, this is the required solution.

Mark Brainliest.
<u>Given:</u>
Mass of object, m = 2 kg
Distance, h = 5 m
<u>To determine:</u>
The potential energy and work done
<u>Explanation:</u>
Step 1: The potential energy of the object is given as:
PE = mgh
m = mass of the object, g = acceleration due to gravity = 9.8 m/s2; h = height
PE = 2 kg * 9.8 ms-2 * 5 m = 98 kgm²s⁻² = 98 J
Step 2: The work done by gravity can be expressed as:
W = Force * distance = F*h
F = mg = 2 * 9.8 = 19.6 N
W = 19.6 * 5 = 98 J
Ans: The potential energy and work done = 98 J
