Answer:
1) , 2)
Explanation:
1) The kinetic energy due to the rotation is:
Where and are the moment of inertia and angular speed, respectively. The moment of inertia of the circular cone is:
The kinetic energy is:
2) The moment of inertia of the ellipsoid is (where a is the major semiaxis):
The kinetic energy is:
Answer:
Option C
Explanation:
As we know, weight = mass x acceleration due to gravity.
Therefore, the alien would weigh more on Saturn as compared to Earth because the acceleration due to gravity is more on Saturn than Earth.

Answer:
1000 Kilograms
Explanation:
Force is equal to mass times acceleration so if the force is 3000 and the acceleration is 3 m/s^2 then all you need to do to find the mass is divide 3000 by 3 which gives you 1000
Option (d) is correct. 800 calories of heat is released.
Explanation:
The formula for the heat is given by
Q= m L
Q= heat energy
m= mass =10 g
L= latent heat of fusion=80 cal/gram
so Heat energy= Q= 10 (80)=800 cal
the heat energy is released.
so 800 calories of heat is released.
