What type of energy is involved when a river moves sediment and erodes its banks?a. chemical energy
b. gravitational energy
c. potential energy
d. kinetic energy

What happens as gravity pulls water down a slope?
a. Kinetic energy changes to potential energy.
b. Both kinetic and potential energy vanish.
c. Energy is stored for future use.
d. Potential energy changes to kinetic energy.

Answers

Answer 1

Answer: First question: The type of energy involved when a river moves sediment and erodes its banks is: option d. Kinetic energy. Kinetic energy is the energy associated with motion. A body (in this case the water) that moves has an energy associated with its motion that is proportional to the speed (exactly to the square of the speed). When the water collides with the banks it is the kinetic energy of the river that erodes it Second question: the answer is the option d. As gravity pulls water down a slope potential energy changes to knietic energy. This is the, water loses altitude and gains velocity. The potential energy. which is proportional to the height, decreases and the kinetic energy, which is proportional to the square of the speed, increases.

Answer 2

Answer:

Answer:

Question A: D., or "kinetic energy".

Question B: D., or "Potential Energy changes to kinetic energy."

Which is occurring when work is being done? energy is being reverted. energy is being decreased. energy is being increased. energy is being transferred.?

Answers

The work is an effect that is observed due to the application of force. Taking the concern of work-energy principle, the work is done when there is a transfer of energy take place.

What is Work Done?

When some magnitude of the force is being applied on an object to displace, then the term used to describe the effect is known as work done.

The mathematical expression for the work done is given as,

W = F × d

here,

F is the magnitude of applied force.

d is the displacement.

If we compare work with energy then, Energy, on the other hand, is the ability to do work. According to the work-energy principle, a change in the kinetic energy is equivalent to the net work done by the object. Therefore, energy is being transferred from one point to another when work is being done.

Thus, we can conclude that the work is done when a transfer of energy takes place.

Answer;

Energy is being transferred

Explanation;

Work is the force applied over a given distance, in other words work is the product of force and distance.

Work = force × distance.

Work is measured in Joules.

Energy on the other hand, is the ability to do work.
According to the principle of work-energy a change in the kinetic energy is equivalent to the net work don e by the object. Therefore, when work is being done energy is being transferred from one point to another.

In which state of matter is a substance unable to transfer heat by convection

Answers

Convection is the movement of molecules in a solution according to the kinetic energy imparted by heat energy. This happens in liquids, gases, and plasmas. It can't occur in solids simply because they are just that. Solids. If the solid is heated enough to break the cohesion then it will turn to a liquid. Hope this helped. :)

What is work done by a person in moving a block of mass 2kg on a frictionless floor up to a distance of 5m?

Answers

If the floor is truly frictionless, then ANY force, no matter how small, applied for
ANY time, no matter how short, will set the block in motion. The force can then
be taken away, because on a frictionless surface, NO force is required in order
to keep the block moving.

The work done is equal to the kinetic energy you want the block to have. That
can be as much or as little as you feel like giving it.
