Answer:
Explanation:
When the pendulum falls freely the net acceleration due to gravity is zero.
As we know that the time period of simple pendulum is inversely proportional to the square root of acceleration due to gravity, thus the time period becomes infinity.
In order for the refrigerator not to tip over, the maximum acceleration of 1.86 m/s² must not be exceeded.
<h3>What is acceleration?</h3>
The term acceleration has to do with the rate at which velocity changes with time.
We have to take the moments at the tipping point of rotation as follows;
Clockwise moment = Anticlockwise moment
Hence;
F₂ * 1.58 m = F₁ * 0.67 m
The weight at half the width= 30 cm or 0.3 m
Height of refrigerator = 158 cm 0r 1.58 cm
Then;
m * a * 1.58 = m * 9.81 * 0.30
a = 1.86 m/s²
In order for the refrigerator not to tip over, the maximum acceleration of 1.86 m/s² must not be exceeded.

Answer:
Depends on the capacity of battery. Mostly our phones flashlight can be used up to 8 to 10hrs continuosly
Explanation:
Capacity of the battery is level to which battery is charged, & amount of current drawn by the flashlight, you can calculate the answer yourself if u know the capacity of that light.
Moreover you can calculate this by using equation,
E =Pt
So, for time
t=E/P
Batteries are rated in Amp hours, like 10 amp hours will supply us 1 amp for 10 hours
2 amps will give us 5 hours
