•Work done is equal to
Mgh = 90*9.8*1.5
1587.6 j
thus power is equal to work done by time
1587.6/3
529.2 j/secs
Answer:7 cm
Explanation:
Given
one sphere has a radius(r) of 4.85 cm
Also another sphere has a mass 3 times the previous one
since the density remains same therefore
second sphere has a volume 3 times of former.
Let R be the radius of bigger Sphere


Answer:
500 cm
Explanation:
Diameter of Milky Way = 
Here, this distance is equal = 25 cm


Distance between the Andromeda galaxy and Milky Way is 2 million ly

Hence, the plates would be 500 cm apart
