Answer:
Part 1)

Part 2)

Part 3)

Part 4)
Since torque on right side is more so here it will turn and slip over it
Explanation:
As we know that the block A is placed at distance
d = 50 cm from the hinge at 70 cm mark
So torque due to weight of A is given as

the block B is placed at distance
d = 30 cm from the hinge at 70 cm mark
So torque due to weight of B is given as

Now torque due to weight of the scale is given as


now torque on left side of scale is given as


Torque on right Side is given as

Since torque on right side is more so here it will turn and slip over it

Answer:

Explanation:
Given:
- time taken by the sun to complete one revolution,

- radial distance of the sunspot,

<u>Therefore, angular speed of rotation of sun:</u>

<u>Now the tangential velocity of the sunspot can be given by:</u>



Inertia is the resistance of an object to moving or stopping
