A material through which charges cannot move easily?

Physics
1 answer:
Naily [24]2 years ago
4 0

Answer: A material that does not easily allow a charge to pass through it is called an Plastic and rubber are good insulators. Many types of electric wire are covered with plastic, which insulates well. The plastic allows a charge to be conducted from one end of the wire to the other, but not through the sides of the wire.

In-s [12.5K]

When a snowball turns into a puddle of water, we know that (the snow ball gains energy and changes from a solid to liquid).

This is correct due to the fact that particles of the snowball are gaining speed and so it is heating up, when the solid's temperature reaches the melting point, it will become a liquid.

Therefore, D is the correct answer.

A 10.3 kg block of ice slides without friction down a long track. The start of the track is 4.2 m higher than the end of the tra
Agata [3.3K]
Hello

1) Since there is no friction between the ice and the track, there is no loss of energy in the motion, so we can apply the law of conservation of energy.
The total energy E (sum of potential energy P and kinetic energy K) must be conserved:
E=P+K  

2) At the beginning of the motion, the total energy of the object is just potential energy:
E_1=P=mgh 
where m is the mass, g=9.81~m/s^2 is the gravitational acceleration, and h=4.2~m is the initial height of the body.

3) At the end of the motion, this potential energy has converted into kinetic energy, and so the total energy at this point is 
E_2= \frac{1}{2}mv^2
where m is the mass and v is the final velocity of the object.

4) We said that the total energy must be conserved, therefore we can write
E_1 = E_2
and so:
mgh= \frac{1}{2}mv^2
from which we can find v, the velocity:
v= \sqrt{2gh}= \sqrt{2\cdot9.81~m/s^2 \cdot 4.2~m}=9.08~m/s
