Answer:
D. 2.5 V
Explanation:
Electric potential of a point in space is a scalar magnitude that allows a measurement of the electric field at that point to be obtained through the electrostatic potential energy that a electric charge would acquire if it is placed at that point.
Average acceleration = (change in speed) / (time for the change)
Average acceleration =
(speed at the end of the 14 seconds) / (14 seconds)
Answer:
6 beats
If one fork beats once and another twice in the same time period
you would hear 1 beat. (Same for 2 and 3 beats).
Answer:
centripetal acceleration of the ball is 6.9 m/s/s
tangential speed of the ball is 2.2 m/s
Explanation:
As we know that ball complete 5 rotations in 10 seconds
so frequency of rotation of ball is given as

now we know that angular frequency is given as



Now centripetal acceleration is given as



now the velocity of the ball at this angular frequency is given as
