Hello there,
The word 'repeatable' means, the scientific experiment is repeated in the same way, with the same methods and analysis.

Hope this helps :))

An RLRL circuit with with a 1212-ΩΩ resistor and a 0.06−H0.06−H inductor carries a current of 1A1A at t=0t=0, at which time a vo

Answer:

The equation of current is $I=0.86 cos \left (120 t + \frac{\pi}{2} \right )$

Explanation:

Resistance, R = 12 ohm

Inductance, L = 0.06 H

E (t) = 12 cos (120 t)

Compare with the standard equation,

$E=E_{0}cos (2\pi ft)$

$2\pi ft = 120 t \\\\\\w = 2\pi f = 120 rad/s$

So, the inductive reactance is

XL = w L = 120 x 0.06 = 7.2 ohm

The impedance of the circuit is

$Z =\sqrt{12^2+7.2^2}\\\\Z = 14 ohm$

The current leads by 90degree so the equation of current is

$I=\frac{Eo}{Z} cos \left (120 t + \frac{\pi}{2} \right )\\\\I=\frac{12}{14} cos \left (120 t + \frac{\pi}{2} \right )\\\\I=0.86 cos \left (120 t + \frac{\pi}{2} \right )$

The average force exerted on the ball by the glove will be 129 N.

<h3>What is force?</h3>

Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.

Given data;

Mass,(m)=0.15-kilogram

Initial speed,u=43 meters per second

Time period,t= 0.050 seconds

Average force exerted,F=?

The average force exerted on the ball by the glove is;

$\rm F = m\frac{v-u}{t} \\\\ F=0.15( \frac{43-0}{0.050} )\\\\ F=129 N$

Hence, the average force exerted on the ball by the glove will be 129 N.
