Answer:
The average force exerted on the pier is N
Explanation:
Given :
Mass of ship Kg
Distance m
Velocity
Now find the average velocity,
Now find the time taken by ship to travel 4.44 m.
sec
Now calculating average force,
Where = 0.652
N
Therefore, the average force exerted on the pier is N
Answer:
<em>Only gravity acts on B but there is an additional residual force from the hand on A.</em>
Explanation:
All bodies are constantly under the effect of gravity. Gravity is what gives us weight here on earth. Gravity acts downwards, and helps to decrease the deceleration of a body moving up and accelerating a body that travels downwards. For the ball A, traveling upwards, the upwards movement is due to the force on it impacted on it from the hand. As A tries to go up, gravity tries to decelerate it until it will come to a stop and then fall downwards under gravity. For body B, descending down means that only gravity forces acts on it at that point, if we ignore buoyant forces and air resistance. And B accelerates as it falls down towards the juggler.
Answer:
Liquid I think because it is room temperature.
Explanation:
C. the left plate is positively charged
when looking at these arrows imagine there is a positive electron at the beginning of the arrow. Since the electrons are going towards the plate to the right it is attracted to the negatively charged plate. These electrons want to get away from the positively charged plate because same charges repulse each other
