Physics
1 answer:
Alchen [17]3 years ago
5 0

Answer:

c] a difference in electric potential

Explanation:

Here is the complete question

In the diagram, the arrow shows the movement of electric charges through a wire connected to a battery. What causes the electric charges to flow from one end of the battery to the other? a] a balance in electric potential b] a balance in resistance c] a difference in electric potential d] a difference in resistance

This is because a difference in electric potential due to the battery at the two ends of the wire, will produce an electromotive  force (due to the battery) which will thus cause the charges to move through the wire.

Draw and label a picture or make a real life model of something to display conservation of energy. Make sure it is something tha
sweet-ann [11.9K]
The picture shows it has a real life something to display conservation of energy  with kinetic energy and potential energy. 


Five sentences are for potential and kinetic energy. Potential energy is to energy an object when it stores. Kinetic energy is something to motion. When the potential energy is slows down the potential energy it might be increases. As from the object when the speeds up and it is decreases to potential energy.

Kinetic energy is to calculated by KE= mass×velocity²/2 as a fraction.

Potential energy is to calculated by PE= mass×g×height.

And the another picture it has a <span>energy, kinetic energy, mechanical energy, conservation of energy.

How could two waves on a rope interfere so the rope does not move at all?
coldgirl [10]

Answer:

If a crest formed by one wave interferes with a trough formed by the other wave then the rope will not move at all.

Explanation:

Assume a straight rope tied to both ends is at rest. When a wave is created at one end of the rope, it travels to the other end of the rope through formation of alternative crest and trough. Due to these crest and trough the rope shifts up and down.

But when there are two waves travelling through the rope and both have opposite direction (directed towards one another) in such a way that crest formed by one wave is interfering with the trough formed by the other wave then due to this interference the waves will cancel the effects of each other on the rope and rope will be stable.

A man weighing 720 N and a woman weighing 500 N have the same momentum. What is the ratio of the man's kinetic energy Km to that
tiny-mole [99]

Answer:

Because weight W = M g, the ratio of weights equals the ratio of masses.

(M_m g)/ (M_w g) = [ (p^2 Man )/ (2 K_man)] / [ (p^2 Woman )/ (2 K_woman)

but p's are equal, so

K_m/K_m = (M_w g)/(M_m g) = W_woman / W_man = 450/680 = 0.662Explanation:

Which solid dissolves faster in water?<br><br> sugar cube<br> or<br> powdered sugar
Verdich [7]

Answer: <em>Powdered sugar</em>

Powdered sugar dissolves faster compare to the sugar cube. Because sugar cube has less surface area (the granules are tightly packed) compared to powdered sugar
