Answer:
The force is 
The time is 
Explanation:
From the question we are told that
The mass of the car is 
The initial velocity of the car is 
The final velocity of the car is 
The acceleration is 
Generally the acceleration is mathematically represented as
=> 
=> 
converting to seconds
=>
Generally the force is mathematically represented as
=> 
=> 
Now converting to foot-pound-second we have
=>
Answer:633.8 KJ
Explanation:
Given
mass of water
Initial temperature
Final temperature 
Specific heat of water 
=4190 J/kg-k
heat of vaporization
Heat required for process
=heat to raise water temperature from 20 to 100 +Heat to vapourize water completely

If you are instead clinging to a position halfway from the center to the outer rim of the Ferris wheel, YOUR ROTATIONAL SPEED WILL STILL BE 2 REVOLUTION PER MINUTE.
This is because, every part of the wheel is moving with the same speed, so it does not matter where you sit on the wheel, the rotation per minute will still be the same. It is just like travelling inside a motor car, it does not matter whether you are sitting in the front passenger seat or at the back, the speed of the car remains the same.
Answer: Option (C) is the correct answer.
Explanation:
When we heat a fluid then the movement within the fluid makes hot (less dense) material to rise and cooler (more denser) material to sink at the bottom. This process is known as convection.
Thus, in the diagram hot (less dense) water will rise and cooler (more dense) water sinks at the bottom.
Therefore, we can conclude that according to the arrow the label belongs to cooler water sinks.
