Answer:
One of the most important reasons for grounding electrical currents is that it protects your appliances, your home and everyone in it from surges in electricity. If lightning was to strike or the power was to surge at your place for whatever reason, this produces dangerously high voltages of electricity in your system.

Explanation:
From the text of the complete problem found on internet, the expression of the force is:
The rate of change of F with respect to t can be find by calculating the derivative of F with respect to t.
First of all, let's recall the derivative of sine and cosine:
We have to calculate the derivative of a composite function, of the form
Its derivative is given by
By applying this formula to our expression, we find:
And by substituting the given data:
W = 45 lb
we find:
Answer:
A. The electric field lines point outward and the black puck moves backwards. From this I can see that I can't put the red charge in front of the black puck because it will go away from the goal.
B. The electric field lines point inward and the black puck moves forwards and backwards. The conclusion I made from this was the blue charge by itself will not be able to get into the goal.
C.The puck moves faster when the mass increases and moves slower when the mass decreases. The more mass, the more force that is applied to the puck.
D. The relationship between the speed of the black puck and its distance from the blue charge is when the puck is further away from the blue charge, the slower the puck moves away from it.
