Answer:
Latent heat, along with birds, ride those rising columns of air. This brings up a third and the ultimate mechanism by which the Earth's heat escapes into space, which is electromagnetic radiation. Every object, including the Earth's surface, absorbs and radiates heat electromagnetically

Answer:
A and B are both requirements for a solar panel to generate usable current at home.
Explanation:
Solar panel operates through a group of cells, where each one of them captures/convert electrons making them move from one polarised region to another. The excited electrons can move from a region in excess of electrons (p region) to a region with a lack of electrons (n region).
This physical effect of electron moving from one side to another creates what we know as current flow.
This current flow from a solar panel does not vary with time in a determined frequency, so it's constant. This is the definition of a DC current. Since the household devices work with AC (variable sinusoidal current Alternate Current) a converter DC to AC is required.
Due to the fact that the solar panels only operate in the day when they recibe direct sunlight, there is the need to have batteries to store the energy for the night and the times where the sunlight is not enough to provide enough electron flow.
Answer:
The current through the wire is equal to 0.8 A.
Explanation:
Given that,
The length of a copper wire = 2 m
Potential difference = 24 mV
The current through the wire is 0.40 A.
The new potential difference is 48 mV.
We need to find the current through the wire.
As the potential difference is doubled for second wire. So the new current will be :
I' = 2I
= 2 × 0.4
= 0.80 A
So, the current through the wire is equal to 0.8 A.

Answer:
Explanation:
Since the work done is same everywhere in the universe. Hence, the work done in jumping will be same for the person on moon and earth:
