Answer:

The electric field can cause the electrons to move around. Through this influence on electrons, we can give a net direction to the motion of the electrons. This is how we generate an electric current

A conductor is an object that conducts electricity through it, the mechanism of conduction of electricity is that, the electrons present in the atoms of the conductor are in rapid motion, and when we apply some potential difference across it by using cell, battery or anything, it causes those electrons to move in a particular direction and we know electrons have negative charge on it which , so the movement of charge ( electrons ) through a conductor causes electric current.

So, from above we conclude that conduction of electric current through a conductor is only possible due to free electrons present in the conductor's atoms.

Ashen light (or earthshine) is
Annette [7]

Answer:

E

Explanation:

The condition known as Earth shine takes place when the reflecting sunlight from our world illuminates the Moon's dark side. This is usually the result that the dark side of the moon is showered in a dim, faint light. It is also called  as the ashen light of the Moon, or in the wings of the new Moon as the old Moon.

Therefore the correct reason would be e. sunlight reflected by Earth that illuminates the "dark" portion of the Moon.

In-s [12.5K]

Answer:

hope this helps you :)

Explanation:

An object is in motion if its position changes relative to another object. To decide if you are moving, you can use your chair as a reference point. A reference point is a place or object used for comparison to determine if something is in motion.

A ship is towed through a narrow channel by applying forces to three ropes attached to its bow. Determine the magnitude and orie
Y_Kistochka [10]

This question is solved using an available similar problem as data provided for the forces was not given.

Repeat the same steps outlined for your problem.

Regards.

Answer:

F = 1.598 KN , Q = 90 degree (+ y-axis)

Explanation:

Sum of Forces in x-direction to the left (+)

2 cos (30) + 3cos (60) + F*cos (Q) = F_a   ..... 1

Sum of Forces in y-direction to the up (+)

2 sin (30) + F*sin (Q) - 3 sin (60)  ...... 2

Using Eq 2 and solve:

F*sin (Q) = 1.598 KN

F_min when sin (Q) is max, max possible value of sin(Q) = 1 @ Q = 90 degrees.

Hence,

F_min = 1.598 KN

Using Eq 1 @ Q = 90 degrees and F = 1.598 KN:

F_a = 2 cos (30) + 3cos (60)  = 3.2 KN
