Aparticular planet has a moment of inertia of 9.74 × 1037 kg ⋅ m2 and a mass of 5.98 × 1024 kg. based on these values, what is the planet's radius? hint: because planets are the shape of a sphere, the moment of inertia is i = (2/5)mr2.
a) 6.38 x 106 m
b) 2.55 × 106 m
c) 6.52 × 1012 m
d) 4.07 × 1013m

 A)

Explanation:

The equation for the moment of inertia of a sphere is:

(1)

Where:

is the moment of inertia of the planet (assumed with the shape of a sphere)

is the mass of the planet

is the radius of the planet

Isolating from (1):

(2)

Solving:

(3)

Finally:

Therefore, the correct option is A.

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
