A has less energy and lower frequency, while B has greater energy and higher frequency.
The work done by the battery is equal to the charge transferred during the process times the potential difference between the two terminals of the battery:

where q is the charge and

is the potential difference.
In our problem, the work done is W=39 J while the potential difference of the battery is

, so we can find the charge transferred by the battery:
Answer:
Heat has accelerated water atoms enough to break the surface tension which leads the liquid to turn into a gas
Explanation:
The state of a substance depends on the distribution of its atoms, therefore any atmosphere change (in this case heat) enough to change the atoms Distribution results in a change of state.
brainliest please ;)
Answer:
oh thank you for the free points :D
Explanation:
∑F = ma = (90 kg)(1.2 m/s²) = 108 N = 100 N (1 significant digit)
