Answer: 1224 joules

Explanation:

Given variables are:

Power (p) = 68 W

Time taken (t) = 18 seconds

work done (w) = ?

Recall that power is the rate of work done per unit time i.e Power is obtained by dividing the work done by the time taken.

Hence, Power = work / time

Make work the subject formula

work = power x time

work = 68 watts x 18 seconds

work = 1224 joules

Thus, 1224 joules of work is done.

How does the height from which you drop the ball relate to the height that the ball bounces back up?
Stels [109]
The higher you go the more potential energy there is, and the lower it is the more kinetic energy there is, so the more kinetic energy there is the higher the ball will bounce.

create a formula giving the strength of the induced field (B) i terms of current (I) and the distance from the wire to the probe
iren [92.7K]
So we need to find the formula for magnetic field B using the current (I) and the distance from the probe (d). So, We know that the stronger the current I, the stronger the magnetic field B. That tells us that the I and B are proportional. Also we know that the strength of the magnetic field B is weaker as the distance d of the probe increases. That tells us that B and d are inversely proportional. So our formula should have B=(I/d)*c where c is a constant of proportionality. c=μ₀/2π where μ₀ is the permeability of free space. So finally our formula is B=(μ₀I)/(2πd).
