I think it might be a gravitational pull
The mantle. It is also the largest earth layer, making up about 84% of the earth.
Answer:
Explanation:
Magnitude of tension
= centripetal force
= m ω²R
= m (2π/T)² R , T is time period of revolution.
= .085 x (2 x 3.14 / .55)² x .84
= 9.3 N .
Answer:
F = 0
Explanation:
Given that,
Force acting to push a bin = 45 N
Mass of the plastic bin, m = 3 kg
The plastic bin is moving with a constant velocity.
We need to find the net force acting on the box. Constant velocity means the change in velocity is equal to 0. It means acceleration will be 0.
As a result, the force acting on the box is equal to 0.
Answer:
D
Explanation:
Because when you stand directly near the source of sound the distance is less and sound is directly proportional to area.
