A straight wire lies along the y-axis initially carrying a current of 10 A in the positive y-direction. The current decreases an
d reverses to 10 A in the negative y-direction, the change in current happening at a uniform rate. In the 1st quadrant a square conducting coil has 2 sides parallel to the y-axis and the other 2 sides parallel to the x-axis. The side of the coil nearest and parallel to the straight wire is at a distance equal to the length of one of the sides of the square. As the current is going from 10 A in one direction to 10 A in the other, in which direction is the induced current in this side of the square coil nearest to the straight wire

Broad questions that we can answer by doing this experiment are <em><u>the effects of electric current</u></em>
<h3>Further explanation</h3>Electric current is the amount of electric charge that flows each unit of time
Electric current occurs due to the movement of electrons due to the difference in potential or voltage (from high potential to low potential) between two points
Electrons will flow through the conducting wire that functions as a conductor
Ohm's Law states that
<em>The potential difference is proportional to the electric current as long as the resistance is constant</em>
A simple electrical circuit consists of a voltage source (battery) and a lamp
Ampermeters to measure the strength of the current, must be installed in series with the load to be measured
By changing the voltage source, with constant resistance from a conductor, different current measurements will be obtained. The greater the voltage, the greater the resulting current.

Answer:
Length, l = 33.4 m
Explanation:
Given that,
Electrical field,
Let the electrical potential is,
We need to find the length of a thundercloud lightning bolt. The relation between electric field and the electric potential is given by :
So, the length of a thundercloud lightning bolt is 33.4 meters. Hence, this is the required solution.
ANSWER
EXPLANATION
Since the body is in equilibrium, total upward forces must equal total downward force.
Also the net horizontal forces acting on the body must be zero.
We need to resolve into vertical and horizontal components.
The horizontal component is
.
The vertical component is
.
Equating the up force to the downward forces gives,
.
This implies that,
.
Also the horizontal forces must be equal.
.
Dividing equation (1) by equation (2) gives,
.
.
Therefore the given angle that must make with the horizontal is approximately 35° to the nearest degree.
