<u>Answer:</u> The voltage needed is 35.7 V
<u>Explanation:</u>
Assuming that the resistors are arranged in parallel combination.
For the resistors arranged in parallel combination:
We are given:
Using above equation, we get:
Calculating the voltage by using Ohm's law:
.....(1)
where,
V = voltage applied
I = Current = 3.75 A
R = Resistance =
Putting values in equation 1, we get:
Hence, the voltage needed is 35.7 V
Answer:
In order to hit the same point with the second ball, you should throw it at an angle of 18° above the horizontal.
Explanation:
Horizontal reach formula for projectiles tells us
where is the initial velocity and
the angle above the horizontal.
Since for both shots the reach must be the same, we have
