Answer:
287.19 kg.m²
Explanation:
Given that :
The mass M of the horizontal platform = 111 kg
The radius R of the uniform disk = 1.67 m
mass of the person standing 
= 64.7 kg
distance of the person standing 
= 1.15 m
mass of the dog 
= 25.7 kg
distance of the dog 
= 1.35 m
Considering the moment of inertia of the object in the system; the net moment of the inertia can be expressed as:
= 
= 
= 287.19 kg.m²
Answer:
15 MW
Explanation:
Work done is a product of force and distance moved.
W=fd where f represnt force while d is distance
Substituting f with 5 kN and 3 000 for d then
W= 5*3000=15000 kW which is equivalent to 15 MW
c.
very small
Being close to the earth can be milseading. I think that if the sun were at the same distance as anohter star, it might be hard to see because it is small, relatiavely speaking
because i said so
