The average speed is 116.66m/s.
Given - The path traced is 14km , time for jogging is 2 hrs=120min
To find the average speed-
calculations-
Speed= 14 000 / 120
= 116.66m/s

Answer:
Explanation:
The angular momentum of an object is given by:
where
m is the mass of the object
v is its velocity
r is the distance of the object from axis of rotation
Here we have:
m = 350 g = 0.35 kg is the mass of the ball
v = 9.0 m/s is the velocity
r = 3.0 m is the distance of the object from axis of rotation (if we take the ground as the centre of rotation)
Therefore, the angular momentum is:
Answer:
The current of the outer coil is
Explanation:
From the question we are told that
The number of turns of the inner coil is
The radius of the inner coil is
The current of the inner coil is
The number of turns of the outer coil is
The radius of the outer coil is
Generally the net magnetic field is mathematically represented as
Now from told that the net magnetic field is common
So
Here is the permeability of free space
making the subject
substituting values
