Answer: 3.27kg
Explanation:
Inertia can be said to be the resistance of an object to a change in its motion. This includes a change in its direction. An object will stay still or keep moving at the same speed and in a straight line, except it is acted upon by an unbalanced external force.
Given F = 30N
r = 0.14m
a = 130rad/s²
Then, T = Fr
T = 30*0.14
T = 4.2Nm
Also, T = inertia * acceleration
Inertia = 4.2/a
Inertia = 4.2/130
Inertia = 0.032
Also, inertia = mr²/2
0.032 = m * (0.14²)/2
0.032 = m * 0.0098
m = 0.032/0.0098
m = 3.27kg
They both-
1) are vector fields
2) they both transmit forces between objects
I hope this helps :))
Answer:
Explanation:
first ball rolls on the porch by total distance
Then again it will move on horizontal floor
also in vertical direction it will drop down
so we have
so magnitude of net displacement of the ball is given as
If this is a true or false question, it is True.
