Answer:

1.67\cdot 10^{-5} T

Explanation:

The magnitude of the magnetic field produced by a current-carrying wire is given by the equation:

B=\frac{\mu_0 I}{2\pi r}

where:

\mu_0=4\pi \cdot 10^{-7} H/m is the vaacuum permeability

I is the current in the wire

r is the distance from the wire

The direction of the magnetic field lines is tangential to concentric circles around the wire.

In this problem, we have:

I=37.9 A is the current in the wire

r=45.5 cm = 0.455 m is the distance  from the wire

Solving for B, we find the magnitude of the magnetic field:

B=\frac{\mu_0 I}{2\pi r}=\frac{(4\pi \cdot 10^{-7})(37.9)}{2\pi (0.455)}=1.67\cdot 10^{-5} T

If Earth orbited the Sun in 9 months instead of 12, then, compared with a sidereal day, a solar day would be
Tcecarenko [31]

Answer:

longer

Explanation:

The relationship between the solar day and sidereal is as follows:

The length of the sidereal day is

= (Solar day) (solar year ÷ solar year +  1 day)

As it can be seen that the day i.e. solar its length would be greater as compared with the sidereal day.

In the case when the earn orbited the sun in 9 months rather than 12 so here the sidereal day would be the similar but the solar day would be longer as compared with the original one

Can work be done on a system if there is no motion?
AfilCa [17]

there is no motion in the direction of the force, then no work is done by that force. ... But the work done on the box is zero since by moving in a straight line at constant speed, its energy is remaining the same.
