Answer:

Say a 14 year old girl was at a construction site and she was asked to move something like a 10,000 pound brick( one brick). She would be acting on it as the unbalanced force but they would still not change their position.

so to say the girl would be doing everything she could to move that brick but the brick would still be in that same spot so the unbalanced force (the girl) would be acting on the thing that was at rest but it wouldn't move.

so the unbalanced force would not really be acting on the thing at rest; even though the unbalanced force was doing something to the brick.

( just think about it and you will eventually get it...just imagine in your head...)

What current is required in the windings of a long solenoid that has 420 turns uniformly distributed over a length of 0.575 m in

WARRIOR [948]

Answer:

The current in the solenoid=0.463 Ampere

Explanation:

Given:

Number of turns , N=420

Length of the solenoid=0.575 m

Magnitude of Magnetic Field, $B=4.22\times10^{-5}\ \rm T$

We know that the magnitude of the magnetic Field inside the solenoid is

$B=\mu_0 ni$

Where

$\mu_0$ is the permeability of free space.
n is the number of turns per unit length
i is the current

According to question

$B=\mu_0 ni\\\\4.22\times10^{-5}=1.24664\times10^{-7}\times \dfrac{420}{0.575}\times i\\=0.463\ \rm Amp$

Hence the current is calculated.

Lamp power with what is the current through the lamp when it is connected to a battery ?

shtirl [24]

Answer:

lamp power with what is the current through the lamp when it is connected to a battery ?

Explanation:

If the light bulbs are connected in parallel, the current flowing through the light bulbs combine to form the current flowing in the battery, while the voltage drop is 6.0 V across each bulb and they all glow. One bulb burning out in a series circuit breaks the circuit.

A very long half-cylinder of radius r carries a total current is uniformly distributed across the circumference. Determine the m

Rufina [12.5K]

The magnetic field along the central axis of the cylinder will be <em>determined </em>using the formula given that all parameters are known

$dBz=\frac{uoR^2di}{2r^3}$

<h3>Magnetic field </h3>

Generally, A magnetic field is also referred to as a vector field that shows the magnetic presence on electric charges and magnetic materials.

The formula for magnetic field is

Where

$u=4\pi*10^{-7H/M}$

Therefore, the magnetic field along the central axis of the cylinder will be determined using the formula given that all parameters are known
