Water will not flow down a flat slide because there is no potential energy difference between the two ends. How could this situa

tion be represented in a electric circuit?

Answer:

Electric current also flows according to the electric potential gradient

Explanation:

As the water flows according to the difference in potential energy, i.e. it flows from higher potential energy to lower potential energy, the electric current also flows in same way.

Electric current also flows according to the electric potential gradient which is measured in volts. So if two points in an electric circuit have the same electric potential then there will not be any flow of current between the two points. For example, in any circuit, if two points A and B both have a potential of 10 volts. Then there will be no electric current between A and B because the potential difference between between A and B is zero (10 - 10 = 0).

Scientists have changed the model of the atom as they have gathered new evidence. One of the atomic models is shown below.
yawa3891 [41]

Answer:

B: The colors of light emitted from heated atoms had very specific energies.

Explanation:

In Thompson's model of an atom the atom is said to be constituted of electrons which are surrounded by a haze of positive charge in order to balance the electrons' negative charges. It is also called plum prodding model because of negatively charged plums which are surrounded by the positively charged pudding.

Now, as the electrons move from higher to lower energy levels a photon which is a particle of light will be given off.

Thus, the correct answer is option B

12. A satellite is put into an orbit at a distance from the center of the Earth equal to twice the distance from the center of t
Kitty [74]

Answer:

Explanation:

F = GmM/d²

As gravity force is proportional to the inverse of the square of the distance,

doubling the distance will reduce the weight to a forth.

F' = GmM/(2d)²

F' = ¼GmM/d²

F' = ¼F = ¼(4000)

F' = 1000 N

The forces acting on a child sitting in a seat are described by the free-body diagram shown. What is the net force acting on the
r-ruslan [8.4K]

The net force is 0 N.

To find the total net force, all you need to do is add the forces.

So 100 + -100 = 0

Most of these questions are trick questions, but if you know Newton's laws of forces, then you should know that all forces should cancel out with each other.

Hope this helps!!!
