Any unit of acceleration must have the dimensions (form) of
(a unit of length) / (a unit of time)²
Remain the same.
Explanation:
The kinetic energy of the ejected electrons, and thus the resulting photocurrent, does not depend on the intensity of the incident radiation. Instead, it depends on the frequency. So since the stopping potential is used to reduce the photocurrent to zero and the photocurrent does not depend on the intensity, the stopping potential remains the same.
Answer:
Using the RC discharge and recharge table it means that after 5 time constant s there is a maximum current of 99.3% and a maximum voltage of 0.7% while form the charge table there will be a maximum voltage of 99.3% and maximum voltage of 0.7% in the RC CIRCUIT USIng
Vc/Vs= e^ -t/z for discharge and
Vc/Vs = e^(1-t/z) for charging
Answer:
Cause, The thickness of the windshield formed between the glass and the lens is zero.
Answer:
It would take 1 s to hear the echo.
Explanation:
Here, the sound covered a total of 340 meters, since it bounces off the canyon wall and travels back to Miles in the form of echo.
The time elapsed can be determined by,
v =
⇒ t =
where: v is the speed of sound in air (343 m/s), D is the distance of the nearest canyon (170 m).
So that,
2D = 2 x 170 = 340 m
Thus,
t =
= 0.9913 s
t = 1 s
It takes 1s for Miles to hear his echo.
