This is for a quiz can you answer all of them..?? Which statement is true regarding the ping-pong ball at the bottom of the ramp in the experiment, “Rolling Along”?

Question 1 options:

No energy was involved in this experiment.

Only potential energy from the ball coming down the ramp will be given to the ping-pong ball at the bottom of the ramp.

The kinetic energy of the ball coming down the ramp will be given to the ping-pong ball at the bottom of the ramp.

All kinetic energy remains with the ball that is coming down the ramp- none of it transfers to the ping-pong ball at the bottom.

If a small car and a large truck were moving at the same rate of speed, what would be a true statement?

Question 2 options:

The car would have a shorter stopping distance.

The truck would have greater kinetic energy.

All choices shown

The truck’s mass is greater, therefore it will have a greater stopping distance

Question 3 (1 point)

When a child slides down a slide (if there is no friction and all of the mechanical energy is conserved) what would happen?

Question 3 options:

Potential energy would turn to Kinetic energy

The energy is destroyed

Kinetic energy would turn in to Potential energy

All energy stays the same

Question 4 (1 point)
Saved
When Is Mechanical Energy Not Conserved?

Question 4 options:

when the electricity is turned off

when you are in outer space

when it is cold outside

when there is significant friction or air resistance or other force affecting on the object.

Question 5 (1 point)
In which example would the most transfer of energy take place from Mechanical energy to Thermal (heat) energy?

Question 5 options:

When a child slides down a waterslide on an innertube

When a metal plate is pressing against a fast spinning piece of steel hard enough to stop it

When a feather falls from the sky

When a skydiver opens her parachute

Question 6 (1 point)
In the experiment, “Rolling Along”, which ball had the greater mass?

Question 6 options:

Golf ball

Neither ball had mass

The masses are the same

Ping-pong ball

Question 7 (1 point)
Conservation of Mechanical energy is defined as

Question 7 options:

potential energy added to kinetic energy

Energy of motion

The sum of the kinetic and potential energies of an object remains a constant value unless there are forces acting on the object that cause a loss of energy overall, such as friction and air resistance.

law of conservation of energy

Question 8 (1 point)
If a ball is rolling down the hill, what force is acting on this ball?

Question 8 options:

Elasticity

Wind energy

Chemical energy

Gravity

Question 9 (1 point)
Imagine a skateboarder rolling down a hill. As the rider travels down, the PE is turning into KE. But the rider is still slowing down. What causes this?

Question 9 options:

The rider is feeling the effects power transfer

The rider is feeling the effects of friction

The rider is feeling the effects Kinetic energy

The rider is feeling the effects potential energy

Question 10 (1 point)
What is true about the distance traveled by the ping-pong ball at the bottom of the ramp?

Question 10 options:

Neither mass nor speed had any impact on the distance traveled.

The greater the distance, the more energy the ping-pong ball had.

The greater the distance, the less energy the ping-pong ball had.

The ping-pong ball did not have any energy as it traveled short or long distances.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
