Answer:
706.5 g
Explanation:
density of fluid, d = 1.35 g/c.c
According to the principle of flotation
Weight of the frog = Buoyant force acting on the frog
V x density of frog x g = V x density of fluid x g
So, the density of frog = density of pod
Mass of frog = volume of frog x density of frog
M = 4/3 πr³ x d
M = 4/3 x 3.14 x 5 x 5 x 5 x 1.35
M = 706.5 g
Thu,s the mass of frog is 706.5 g .
Answer:
They are orbiting earth.So they stay in orbit.
We know that gravity increases with height.
Explanation:
1st Question Explanation:
- Earth's gravity still pull on them.
- Gravity combines with the satellite's momentum from its launch into space.This Combination cause the satellite go into the orbit.
2nd Question Explanation:
- Gravity is caused by the Earth's spinning
- Gravity is notable bless on high mountains or tall buildings.
Yes that's a true statement. That's why grandmother put a hot water bottle to warm up her bed, and not a hot bar of steel or lead.
