The method of heat transfer by which the sun warms the earth is

Answers

Answer 1

Answer: Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection.

Answer 2

Answer: Conduction and convection both require some kind of material stuff
between the heat source and the object being heated.

Since there's no material stuff in the space between the sun and the
Earth, conduction and convection can't do it, and the only way for the
sun's energy to reach the Earth is by radiation.

Voltage difference causes charge to flow from?

Answers

Voltage difference causes charge to flow from higher potential to that of a lower potential.

What is Potential difference?

This is also known as Voltage difference and it is the difference in electric potential between two points.

V= W/Q

where v is potential difference, w is work done and q is charges.

This allows for charges to flow from higher potential to that of a lower potential.

Answer:

Voltage difference causes charge to flow from higher potential to that of a lower potential.

Explanation:

Voltage Difference:

It is work done per unit charge in moving a charge from one point to another point.

V = Voltage difference

W = Work done

Q = Charge

Then,

$V = (W)/(Q)$

unit : Volt or Joule/Coulomb

Flow of charge :

A free positive charge move from a region of higher potential to that of lower potential whereas a free negative charge moves from lower potential region to a higher potential.

Thus, a voltage difference is required for the flow of charge.

A basketball has been left out in the cold. The next day you find that it has become soft. What do you do to get it back to shape and why?a) Leave it alone to warm up
b) Pump it up a little
c) Get a new basketball

Answers

All three answers would adequately solve your "flat basketball" problem, but the answer your teacher is probably looking for is a). When the air inside the basketball cooled off, the particles came closer together, causing the ball to deflate. If the air inside the ball was warmed back up, the particles would spread out more (the air would expand) and the ball would inflate again.
Hope that helps!!

The cold made the particles clump to together so the answer could be a or b
