Answer:
Average speed of the swimmer is 4.44 m/s
Explanation:
As we know that the speed is the ratio of distance covered over time interval
so here we can say

so we know that

time taken to complete the trip is

now we have

<span>The importance of discovering gravitational
waves are; one, we can measure the activity between two bodies in orbit in the
universe, two, scientist can estimate the merging of two bodies in the universe
every 15 minutes by using LIGO and three, we can know the behavior of other
bodies that we did not know exist.</span>
Answer:
Part a)
When rotated about the mid point

Part b)
When rotated about its one end

Explanation:
As we know that the angular acceleration of the rod is rate of change in angular speed
so we will have



Part a)
When rotated about the mid point



now torque is given as


Part b)
When rotated about its one end



now torque is given as
