Because field lines don’t all go in to the pole. The bottom half go outwards not inwards.
The main danger is vehicles making u-turns or pulling out without signalling.
Answer:
Explanation:
The formula that you are working with is F = m*a
Since mass is one part of the formula if you increase the mass, you are going to increase the force.
The second one is much more difficult to answer because it is basically incomplete. This is one way to interpret it. If you start at a certain speed and increase during a known time period then effectively you are defining acceleration which is "a" in the formula.
Without those modifications, there is no answer.
A = (Vf-Vi) / t,
a = (6-0)/3 = 2m/s^2,
F = ma = 2 * 2 = 4N
1790 = electrical energy / 2940 seconds
Electrical energy = 5262.6kJ
or
1.79kW X 49/60
= 1.46kWh
