B.
Explanation:
The sound waves are compromised. It decrompesses each time which makes the sound gets lower and lower.
A) Experiments. Opinion polls are used to study people, intuition and imagination are not official studies. Would appreciate brainliest!
We are given with a velocity-distance-time kinematic problem given the different times of two runners and is asked for the difference in distances the runner has ran in the track. we use the formula v= d/t where d is the distance of running, t is time and v is the velocity of the runner.
First runner,
v = d/t = 1000 m / (120+28.13s ) = 6.750826976 m/s
Second runner
Using the same velocity we determine d2.
v = d2/t2 = d2 / (120+28.48s) = 6.750826976 m/s ; d2 = 1002.362789
distance of running track is the difference of the two distance achieved by the runners, delta d= d2 - d = 2.362789 m
As the ball is moving in air as well as we have to neglect the friction force on it
So we can say that ball is having only one force on it that is gravitational force
So the force on the ball must have to be represented by gravitational force and that must be vertically downwards
So the correct FBD will contain only one force and that force must be vertically downwards
So here correct answer must be
