Out of the given options, weight is influenced by mass and gravity
Answer: Option A
<u>Explanation:
</u>
The object's mass is defined as the quantity of a matter with which the object is formed. It can change its state of matter but the quantity will remain the same. However, the weight is defined as how much force gravity exerts on the object's mass to pull it.
The mass is always same irrespective the location but the weight may vary from one place to the other while talking for the bigger picture. For example, the object's weight may be 60 kg on Earth but when it is measured on the moon, it will be lesser.
The weight of an object generally has nothing doing with the volume and it doesn't depend solely on the gravitational pull. The mass plays a crucial role.
Answer:
Explanation:
Given
Time period
Orbital speed
mass of GS
Radius of Mars
Consider the mass of mars is M
Here, Gravitational pull will provide the centripetal force
Explanation:
The angular momentum is given by the moment of inertia, multiplied by the angular speed of the rotating body:
The angular speed is given by:
Now, we calculate the angular momentum:
The average torque is defined as:
is the angular acceleration, which is defined as:
We have to calculate :
Now, we calculate the angular acceleration:
Finally, we can know the average torque:
