Making a wire thicker has the same effect as making a road wider. It makes it easier for the electron traffic to flow. The resistance decreases, and the current (traffic) increases.

The block gains gravitational potential energy as it gets higher,
and that's the energy that the motor has to supply.
The amount of potential energy gained by the block is
(mass) x (gravity) x (height)
= (2.0 kg) x (9.8 m/s²) x (15 m)
= (2 x 9.8 x 15) kg-m²/s² = 294 joules.
Power = (change in energy) / (time for the change)
= (294 joules) / (6 sec)
= 49 joules/second = 49 watts .
Answer:
The energy received by Earth from the sun is called solar radiation. This includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation also transfers heat.
Explanation:
Earth receives radiation from the sun, the radiation we receive from the sun is known as the electromagnetic spectrum. The electromagnetic spectrum spectrum includes all the types of radiation we receive, from radio waves to gamma rays.
Answer:
You can change the momentum of an object by giving the object more force or less force.
Explanation:
Think about a ball. It is going slow, you push it and you give it more momentum.
