Let us suppose police car and motorist travel in straight line and police car catches motorist after s distance
Distance travel by motorist
----1
Distance traveled by Police car
----2
from 1 & 2 we get
(a)Velocity of Police car after t sec
(b)time taken by police car is
(c)Distance travel by police car
Answer:
Time period at the moon will be 2.828 sec
Explanation:
Let initially the length of the pendulum is l and acceleration due to gravity is g
And time period is given T = 2 sec
So time period of the pendulum is equal to -------------eqn 1
Now on the planet acceleration due to gravity
So time period of the pendulum at this planet --------eqn 2
Now dividing eqn 1 by eqn 2
So time period at the moon will be 2.828 sec
Idk im not very good at math
"D is correct answer." Velocity is the displacement of an object during a specific unit of time. "Hope this helps!" "Have a great day!" "Thank you for posting your question!"
