Answer: The magnitude of the magnetic field is (50μ₀I/r) T or 6.28 × 10^-5(I/r) T.

At the interior region of the coil, the magnetic field will be outward and the exterior region of the coil, the magnetic field will be inward

Explanation: For the magnitude of the magnetic field, please see the attachment below.

The direction of the magnetic field can be determined using the right hand rule, if you place your fingers (excluding the thumb) on a circle to point in the counter-clockwise direction, your thumb will point outwards; and when the thumb moves around the coil, it will point inwards. The direction of the magnetic field is denoted by the thumb.

Hence, at the interior region of the coil, the magnetic field will be outward ( out of the plain) and the exterior region of the coil, the magnetic field will be inward (into the plain)

Answer:

Magnitude = B = (μ₀*N*I /2R)

Direction= The direction of the magnetic field will be find out by the right hand rule.  We will curve the finger of right hand in the direction of the current and our thumb will  show the direction of the magnetic field.  which will be out of the screen.  That is + z direction.

Decay of ______ waste present in waste water leads to unpleasant smell
victus00 [196]

Decay of Schizomycetes waste present in waste water leads to unpleasant smell.

These microorganisms, known as iron and sulfur bacteria, cause hydrogen sulfide to be found in water supplies. They include crenothrix and beggiatoa. Most often found in groundwater supplies, they produce an offensive odor of decaying matter. (I'm not sure)

Q2. You push a crate up a ramp with a force of 10 N. Despite your pushing, the crate slides down the ramp 4 m. How much work did
Ksivusya [100]

Answer:

40 J

Explanation:

From the question given above, the following data were obtained:

Force (F) = 10 N

Distance (s) = 4 m

Workdone (Wd) =?

Work done is simply defined as the product of force and distance moved in the direction of the force. Mathematically, we can express the Workdone as:

Workdone = force × distance

Wd = F × s

With the above formula, we can obtain the workdone as follow:

Force (F) = 10 N

Distance (s) = 4 m

Workdone (Wd) =?

Wd = F × s

Wd = 10 × 4

Wd = 40 J

Thus, 40 J of work was done.

how much force is needed to move a brick with a mass of 345-kg a distance of 28m while doing 1008 j of work?
Travka [436]

    Work = (force) x (distance)

     1,008 J  =  (force) x (28 m)

Divide each side by 28m  :    (1,008 kg-m²/sec²) / (28 m)  =  force

                                           Force =  36 kg-m/s²  =  36 Newtons .
                                                                      (about 8.1 pounds)

It doesn't matter what that force accomplishes.
It could be moving a brick, lifting a fish, or pushing a little red wagon.
In order to do 1,008 joules of work in 28 meters, it takes 36 N of force,
in the direction of the 28 meters.
