<span>The larger the current flowing in a wire, the stronger the magnetic field
is that surrounds the wire. 

That's why, if you want to make an electromagnet stronger, one way to
do it is to add another battery.  By increasing the voltage, you'll increase
the current flowing in the coils of wire, and the electromagnet will be stronger.</span>

Answer:

option (a) and (C)

Explanation:

The magnetic field strength due to a current carrying wire is directly proportional to the amount of current flowing through the conductor and the length of the conductor. By the Biot Savart's law, the amount of magnetic field strength produced due to a small length element is given by

dB = k dl x i / r^2

Where, dl is the small length element, i be the current and r be the distance from the conductor where the magnetic field strength is to be calculated.

Vladimir [108]

Answer:

Explanation:

The equation for Power is

P = Work/time to do work and the equation for work is

Work = FΔx

We first need to find the amount of work done, then we can find the power it took to do that work.

W = 2000(9.8)(28) so

W = 550,000 N*m

Now we fill that into the power equation:

P=\frac{550000}{30} gives us

P = 18000 Watts. But we need kW, so we divide by 1000 to get

P = 18 kW of power.

Can a falling object reach terminal velocity in outer space? Explain.
Damm [24]
Ith air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 m/s (195 km/h or 122 mph) for a human skydiver. ... (On the Moon, the gravitational acceleration is much less than on Earth, approximately 1.6 m/s2.)

irakobra [83]

Answer:

Explanation:

The velocity of the vehicle would increase because the the tanks (when filled with water) must have exerted a force which would reduce the velocity of the vehicle at a certain pressure on the gas pedal. Note that force equals mass multiplied by acceleration; as the mass decreases, so the force decreases. Thus, when the mass exerted by this tanks (on the vehicle) decrease as a result of the hole punctured in them, the force exerted by the tanks would also decrease causing an increase in velocity of the pick up truck when the same pressure is applied on the gas pedal throughout (before and after the puncture).

The conservation law that applied here is the law of conservation of energy which states that energy can neither be created nor destroyed but can be transformed from one form to another. This is because the energy the vehicle used in carrying the load (the tanks) was transformed to the energy that resulted in increasing  it's velocity (no new energy was formed as the pressure on the gas pedal remained the same).
