Answer:
Workdone = 25500Nm
Explanation:
Given the following data
Force = 425N
Distance = 60m
To find the workdone
Workdone = force *distance
Substituting into the equation, we have
Workdone = 425*60
Workdone = 25500Nm
The calculated total mechanical energy will reduce if the oscillation is not perpendicular to the photogate.
<h3>Mechanical energy at the lowest position of the pendulum</h3>
The mechanical energy at the lowest position of the pendulum is calculated as follows;
<h3>When the direction of the motion changes</h3>
let the velocity of the pendulum = vsin(θ)
when the velocity is perpendicular = vsin(90) = v
At any direction different from perpendicular direction, the mechanical energy reduces by;
Thus, the calculated total mechanical energy will reduce if the oscillation is not perpendicular to the photogate.

Answer:
The total electric flux through the shell = 34804 N.m²/C
Explanation:
φ = E.A ........................... Equation 1
Where φ = total electric flux through the shell, E = Electric Field, A = surface Area of the sphere
But,
A = 4πr² ................................... Equation 2
Where r = radius of the sphere.
Given: r = 1.4 m,
constant: π = 3.143
Substituting these values into equation 2,
A = 3.143(1.4)²
A = 6.16 m²
Also Given: E = 5650 N/C,
Substituting into equation 1,
φ = 5650(6.16)
φ = 34804 N.m²/C
Thus the total electric flux through the shell = 34804 N.m²/C
Hello!
Static electricity occurs due to an imbalance in positively and negatively charged atoms. An example of this is when you take your clothes out of the dryer, and feel a slight sting when touching them. Another example of static electricity is lightning.
Current electricity occurs when there is a constant flow of electrons, such as in plug-operated machinery or anything operated using a battery. :)
