Answer:
Explanation:
3. Newton’s third law explains how every action has an equal but opposite reaction, meaning that forces comes in pairs. While the locomotive’s wheels are pushing back against the ground as the action force, the ground is producing a reaction force towards the locomotive, propelling it forward. Another pair of forces that act on the locomotive is gravity and normal force. While gravity is pulling the locomotive towards the ground, the normal force the ground exerts on the locomotive is why the locomotive doesn’t fall through the ground.
4. The force of Earth’s gravity on the Sun is weaker than the force of the Sun’s gravity on Earth. The Sun’s attraction affects the motion of Earth more than the Earth’s attraction affects the Sun’s motion because according to Newton’s second law, force has mass as one of its factors. The Sun has a significantly higher mass than Earth, meaning that its force of gravity would also be significantly higher. Newton’s third law is why the Earth doesn’t get marginally closer to the Sun, stating that every action has an equal and opposite reaction. As the Sun is pulling Earth towards itself, Earth is pulling away from the Sun.

Answer:
B. 4700 J
Explanation:
Given the following data;
Mechanical energy = 4900J
Mass = 100kg
Velocity = 2m/s
To find the potential energy;
Mechanical energy = kinetic energy + potential energy
First of all, we would determine the kinetic energy of the object;
K.E = ½mv²
K.E = ½*100*2²
K.E = 50*4
K.E = 200 J
Substituting into the equation, we have;
4900 = 200 + P.E
P.E = 4900 - 200
P.E = 4700 Joules
A tornado<span> is a violent rotating column of air extending from a thunderstorm to the ground. The most violent</span>tornadoes<span> are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards. They can also drive straw into trees.
