Answer:
V = 19m/s
Explanation:
Given the following data;
Initial velocity, U = 4m/s
Acceleration, a = 0.5m/s²
Time, t = 30 seconds
To find the final velocity, we would use the first equation of motion;
V = U + at
Where;
V is the final velocity.
U is the initial velocity.
a is the acceleration.
t is the time measured in seconds.
V = 4 + 0.5*30
V = 4 + 15
V = 19m/s
Therefore, his final velocity is 19 meters per seconds.
Inductor releases its stored energy before it is removed from the circuit.
<h3>What is an inductor?</h3>
- A passive two-terminal electrical device known as an inductor, also known as a coil, choke, or reactor, stores energy in a magnetic field as electric current passes through it.
- Typically, an inductor is made out of insulated wire twisted into a coil. According to Faraday's law of induction, the time-varying magnetic field generates an electromotive force (e.m.f.) (voltage) in the conductor as the current through the coil varies.
- Lenz's law states that the induced voltage has an opposing polarity (direction) to the change in current that caused it. Inductors so reject any changes in the current flowing through them.
- Inductance, which is the ratio of voltage to current change rate, is a property of inductors.

Adhesive.
Adhesive is the force of attraction between molecules of different kind. Liquid flows upward the wick because the adhesive force between the wick and the liquid is higher than cohesive forces in the liquid.
When the adhesive force between the wick and the liquid is high we have capillarity taking place. This cause the liquid to move up the wick.
If the length and linear density are constant, the frequency is directly proportional to the square root of the tension.
As we know that :
Power, is in Meter. So divide focal length by 100
