Answer:

C. Substances evaporate at different rates

Explanation:

  • Different substances have different evaporation rates because each substance requires different amount of energy for liquid molecules to separate and hence change its state from liquid to gas i.e. Evaporation.

Hi, thank you for posting your question here at Brainly.

Electricity is the flow of electrons due to a potential difference called voltage. The electrons naturally flows from a higher to a lower potential. Thus, the electrons flows from the positive to the negative terminal.

A transformer only works with which type of current?
Elden [556K]

Answer would be: alternating.There is no electrical connection between the two coils. These only work if alternating current is supplied to the main coil. If DC was supplied, there would be no flow of current in the minor coil.

A solid nonconducting sphere of radius R carries a charge Q distributed uniformly throughout its volume. At a certain distancer1
Jobisdone [24]

Answer:

The magnitude of the electric field in the second case will be \frac{1}{8} of the electric field in the first case

Explanation:

The electric field at a distance r_1 < R from the center of the sphere is given by

the formula E_1  = \frac{kQr_1}{R^3}  

where R is the radius of the sphere, and, Q is the charge uniformly distributed on the sphere.

It is given that the same charge Q is distributed uniformly throughout a sphere of radius 2R and we have to find the electric field at same distance r_1 from the center.

In the second case the electric field will be given by

E_2 = \frac{kQr_1}{(2R)^3}  = \frac{kQr_1}{8R^3}  =\frac{1}{8}  \frac{kQr_1}{R^3} = \frac{1}{8} E_1

Therefore the magnitude of the electric field in the second case will be \frac{1}{8} of the electric field in the first case.
