Answer:

<em>Since there are no choices provided, I have answered the question according to my understanding.</em>

free electrons

Explanation:

When it comes to electric currents, there are certain things or objects that allows it to flow. These things are known as "conductors." What sets conductors apart from insulators (poor conductors of electricity) is<em> its ability to let the electric current flow through them.</em> This is because of the "free electrons" they have within them. These electrons are able to move from one atom to the other when an electric field is present.

So, this explains the answer.

1) Assertion: On Freely suspending a current carrying solenoid, it comes to rest in N-S direction just like a bar-magnet.
xz_007 [3.2K]

Answer:

Explanation:

1. A solenoid is a coil which has many turns. When current flows through a solenoid, it behaves as an electromagnet. This behavior is due to the magnetic effect of an electric current thereby causing one end of the solenoid to behave as a north pole, while the other end as a south pole.The external influence of the earth's magnetism constrains the solenoid to come to rest in a N-S position just like a bar magnet.

2. The magnetic compass can be used to trace the alignments or patterns of the magnetic field around a current carrying wire. When current flows in a wire, it induces magnetic field around it. If the value of current is increased, the strength of the magnetic field would increase and vice versa. This shows that current is proportional to the strength of the magnetic field produced around the wire. Thus this causes a deflection of the compass appropriately, as the deflection of the compass is proportional to the strength of the field.

A 25N force is applied to a bar that can pivot around its end. The force is r=0.75 m away from the end of an angle at 0= 30. wha
Alecsey [184]

Answer:

<h2>9.375Nm</h2>

Explanation:

The formula for calculating torque τ = Frsin∅ where;

F = applied force (in newton)

r = radius (in metres)

∅ = angle that the force made with the bar.

Given  F= 25N, r = 0.75m and ∅ = 30°

torque on the bar τ  = 25*0.75*sin30°

τ = 25*0.75*0.5

τ = 9.375Nm

The torque on the bar is 9.375Nm

If you decrease the distance between successive crests of a wave, this changesA. The frequency.B. The wavelength.C. The speed.D.
Feliz [49]

Answer:

option E

Explanation:

The correct answer is option E

Writing the relation between wavelength and frequency

      f = \dfrac{v}{\lambda}

f is the frequency

v is the velocity of wave

λ is the wavelength

From the above expression we can clearly see that frequency is inversely proportional to wavelength.

When the distance between the two successive crest is decreased then wave length of the wave also decrease.

If wavelength of the wave decreases then frequency of the wave increase.

hence, we can say that both wavelength and the frequency changes.
