Answer:
v_average =0
Explanation:
In kinematics the average speed defined with the distance interval traveled in a given time interval
V = Δx /Δt
in this case the tennis ball travels a distance h to the highest point and a distance h from the highest point to the floor, so the distance you travel zero
Dy = h -h = 0
therefore the average speed should be zero
v_average =0
Answer:
Secondary voltage on second transformer is 200 volt.
Explanation:
It is given two transformer
Let us consider first transformer.
Number of turns in primary
Numb er of turns in secondary
Now consider second transformer
Number of turns in primary
Number of turns in secondary
Now it is given that same voltage of 50 volt is applied to primary of both the transformer.
For second transformer
So secondary voltage on second transformer is 200 volt
Since direction is part of velocity, and the object is moving in a circle, its velocity is constantly changing.
Answer:
The maximum height is 10.0m
The strongest of the natural forces is Strong Nuclear, followed by Electromagnetic, then Weak Nuclear and lastly Gravitational.
So from weakest to strongest: gravitational --> weak nuclear --> electromagnetic --> strong nuclear
