Answer:
<em>Option D </em>
<em>Electric meter is used to </em><em>measure</em><em> the amount of electric current</em>
Explanation:
Conduction is the heat transfer through a stationary matter by the physical contact.
For example, the heat transferred between electric burner of stove and bottom of pan is transferred by the process of conduction.
Convection is heat transfer by macroscopic movement of the fluid. The particles of the fluid carry the current within themselves.
For example, the water is the pot is warmed overall by heat transferred by the process of convection.
Umm the Water cycle sorry I’m trying
Answer:

Explanation:
Density is defined as mass ler unit volume, expressed as

Where m is mass,
is density and v is the volume. For a sphere, volume is given as

Replacing this into the formula of density then

Given diameter of 2.24 in then the radius is 1.12 in. Substituting 0.82 lb for m then

I think the answer is the third option
