You perform an experiment in which you measure the distance traveled by a projectile fired with different initial velocities. Wh
2 answers:
During the motion of projectile we know that the distance traveled by the object is in the range of meter
So the object will move to certain distance at different velocity which we have to measure by a device which has range of distance from 0 meter to several meters
So the correct device to measure it is

Answer:
Explanation:
The ball will rise decreasing its speed until it reaches the highest point where its speed will be zero. From this point the tennis ball will begin to fall again, in the free fall the tennis ball will gain speed but now in the opposite direction. When it returns to the same point where it was launched, its speed will be the same as the one that was launched but with the opposite sign.
We can check this using the equation:
where
ang h is the height, but because the ball returns to the same point where it started, h =0
then
the initial and final velocity will be the same in number, but we know that the ball is going in the opposite direction, so the final velocity must have the opposite sign from the initial velocity
so if ,
Answer:
The correct option is A. 18 V
Therefore,
Explanation:
Given:
Total Voltage,
V = 56 V,
Voltage drop
To Find:
(Assumed ,as it is not given clearly in the question)
Solution:
So in series combination total Voltage is given as
Substituting the values we get
Therefore,
