Question

5 A free fang object has acceleration due to a.weight
b. energe
C earth's gravity
d. velocity of wind​

Answer 1

Answer:

There are two conditions for a body to be in equilibrium:

(i) Sum of forces acting on body= 0

(ii) Resultant torque = 0

If a body is in at rest, resultant force is zero. If a body is moving with uniform velocity, still the resultant force is zero. These bodies will be in equilibrium. Similarly a rotating ceiling fan is in equilibrium as net torque acting on it is zero.

Some physicists/teachers present the following two examples as bodies at rest but not in equilibrium:

1. Body at highest point when thrown upward against gravity.

2. Pendulum at its extremes.

please mark as brainliest.....

Answer 2

Answer:

velocity of wind.

Explanation:

Acceleration is the rate of changing velocity.

Acceleration occurs as velocity increases.
