I think 100,375 J.
Hope it helps :)
Answer:
Average speed will be 30.30 m/sec
Explanation:
We have distance d = 10 km
Time to reach university to home = 20 min
We know that 1 hour = 20 min
So 20 minute
We have to find average speed
We know that distance = speed × time
So
So the average speed will be 30.30 m/sec
Answer:
Explanation:
Given that,
Mass of the object, m = 29 kg
Torsion constant of the wire, K = 1.14 N-m
Number of cycles, n = 98
Time, t = 74 s
To find,
The rotational inertia of the object.
Solution,
Relationship between the moment of inertia, time period and the torsion constant of the spring is given by :
Where I is the moment of inertia
K is spring constant
Let T Is the time period of oscillation, such that,
So, the rotational inertia of the object is .
