Answer:
Option A
Explanation:
An Uninterruptible Power Supply abbreviated as UPS is used in case of the failure of the power mains or the input power in order to ensure uninterrupted power supply.
The Ac voltage is first converted to DC and then again inverted to the AC and is fed to the system.
Thus if the UPS malfunctions then in order to check the output using multimeter we use AC voltage setting because the UPS purely supplies AC power, even if the power is supplied from its internal battery then also it inverts the DC into AC and then supply.
If this pendulum is situated in an elevator that is moving upward at a speed of 9.00 m/s2, the period of its minor oscillations is 4.34s.
<h3>One oscillation is it a period?</h3>
Period is equal to the length of one oscillation.
T. T . The frequency is the number of oscillations that occur in one second.
<h3>Short answer: How long does a pendulum swing?</h3>
A simple pendulum's period is: The symbol "T" stands for the period of time needed by the pendulum to complete one complete oscillation. The length of a basic pendulum: It is described as the distance the pendulum moves away from equilibrium and toward one side.
Since the elevator's oscillations for this pendulum are situated there and it is climbing at a 9.0 mph,
use G = 9.8 + 9.0 = 18.8 m/s²
Period T=2π√(L/G)
T= 2π√(9/18.8)
T=4.34s

It's is a cell wall. A cell wall surround plant cells and it is a nonliving rigid layer that protects the cell from the outside.
Answer:
white
Explanation:
This experiment causes lines of different colors because the constructive interference depends on the wavelength, so for different wavelength, the position of the maximum will be different.
Now, in diffraction fo a single slit we always have a central maximum (for all the colors)
This means that after the diffraction, we will have that all the colors have a maximum in the center, which will produce white light again, then the color of the central image is white
