Answer:
<h2>320 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 80 × 4
We have the final answer as
<h3>320 N</h3>
Hope this helps you
Answer:
The answer is (C) E= 1/2 kx^2
Explanation:
Answer:B
Explanation: Gravity pulls denser air and water downward, forcing less dense air and water to move upward. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.
Newtons third law of motion is as below
every action has an equal and opposite reaction
#action=force
#reaction =another force
Answer:
58230.08849 Pa
Explanation:
F = W = Weight of the person = 658 N
A = Area to which the force is applied =
When the force is divided by the area to which the force is applied we obtain the pressure
Hence, pressure the foot exerts on the floor is 58230.08849 Pa
