Answer:
6093.2328 J
Explanation:
For cylindrical rod moment of inertia will be


we have given time =0.02 sec
Angular speed =
Rotational KE = 
As stream discharge increases, only velocity increases.
<h3>What is discharge?</h3>
The discharge or volume flow rate is defined as the product of the velocity of the fluid and the area of cross- section of the pipe or tube.
Discharge Q = Area A x Velocity V
Q = AV
The discharge is directly proportional to the velocity of the fluid. When discharge increases, velocity is the only physical quantity that can be changed.
Thus, As stream discharge increases, only velocity increases.

Then the time interval during which the rocket engine provides upward acceleration in 2.1s hope this helps have more photos but can’t put them more in brainliest is appreciated
Answer:
<em>B) 1.0 × 10^5 V</em>
Explanation:
<u>Electric Potential Due To Point Charges
</u>
The electric potential produced from a point charge Q at a distance r from the charge is

The total electric potential for a system of point charges is equal to the sum of their individual potentials. This is a scalar sum, so direction is not relevant.
We must compute the total electric potential in the center of the square. We need to know the distance from all the corners to the center. The diagonal of the square is

where a is the length of the side.
The distance from any corner to the center is half the diagonal, thus


The total potential is

Where V1 and V2 are produced by the +4\mu C charges and V3 and V4 are produced by the two opposite charges of
. Since all the distances are equal, and the charges producing V3 and V4 are opposite, V3 and V4 cancel each other. We only need to compute V1 or V2, since they are equal, but they won't cancel.


The total potential is


Answer:
The precision at which the number was measured
Explanation:
The number of digits that you use to record a measurement indicates the precision of the measurement.
