In a series circuit, each circuit element has the same current. The answer
is letter A. This is because the electrons flowing in a current has only a
single path to follow. There are no other path that the current moves along.
Answer:
40 J
Explanation:
= 4 C
= 2 C
= 20 J
The potential energy is directly proportional to the charge of the particle
The potential energy expected is 40 J
Answer:

Answer:6.71 m/s
Explanation:
Given
Apple fall from a height of 
We need to find the impact speed of apple which can be given by using
where v=final velocity
u=initial velocity
h=Displacement
Assuming initial velocity to be zero
substituting the value we get
Answer:
20 Hz
15.8 times
Explanation:
A
Although the range of frequency for any human's ear is usually said to be between 20 Hz and 20 kHz. And since the question asked for the least intense frequency, that has to be 20 Hz. Essentially the frequency most people perceive the least intense sound is 20 Hz.
B
A 100-Hz sound must be 10^1.2 times or 15.8 times more intense compared to a 1000-Hz sound to be perceived as equal to 60 phons of loudness
