Due to difference in electric potential.
<h3>What is Potential difference?</h3>
The amount of work in an electrical field to move a unit charge from one place to another is known as the electrical potential difference.
Here , the potential difference is the difference in electric potential between two charged substances.
Current is the flow of charges from one end end to another end of a conducting wire connected across a two terminals of a battery.
The potential difference is [provided by the battery across the two terminals due which the charges flow.
Current flow is from positive to negative terminals, indicating the movement of positive charges in that direction.
Hence , potential difference causes the electric charges to flow from one end of the battery .

Using kinematic equation, v^2 - u^2 = 2as. 5^2 - 3^2 = 2a x 16. a = 0.5m/s^2. So particle will deaccelerate at 0.5m/s^2. ( v = final velocity, u= initial velocity, a= acceleration, s= displacement.)
Answer:
Explanation:
The rod will act as pendulum for small oscillation .
Time period of oscillation
angular frequency ω = 2π / T
= 
b )
ω = 20( given )
velocity = ω r = ω l
Let the maximum angular displacement in terms of degree be θ .
1/2 m v ² = mgl ( 1 - cosθ ) ,
[ l-lcosθ is loss of height . we have applied law of conservation of mechanical energy .]
.5 ( ω l )² = gl( 1 - cos θ )
.5 ω² l = g ( 1 - cosθ )
1 - cosθ = .5 ω² l /g
cosθ = 1 - .5 ω² l /g
θ can be calculated , if value of l is given .
1 W = 1 J/s
Watt<span> is the unit of measure for power .
