When a light ray passes from air into water a similar thing occurs: the light ray is bent as it strikes the surface of the water. This 'bending of a ray of light' when it passes from one substance into another substance is called refraction.

A test charge is placed at a distance of 2.0 × 10-1 meters from a charge of 5.4 × 10-8 coulombs. What is the electric field at t
Alborosie
The electric field E of a charge is defined as E=F/Q where F is the Coulomb force and Q is the test charge. 

E=(1/Q)*k*(q*Q)/r², where k=9*10^9 N*m²/C², q is the point charge, Q is the test charge and r is the distance between the charges.

So E=(k*q)/r² 

When we input the numbers we get that electric field E of a point chage q is:

E=(9*10^9)*(5.4*10^-8)/0.2²=486/0.04=12150 N/C.
This is roughly E=12000 N/C =1.2*10^4 N/C
The correct answer is B.

Is there a difference between potential difference, voltage and EMF?
Andreas93 [3]
There may be an esoteric technical shade or nuance of difference.  But I've been an electrical engineer for 40 years now, and have always used them interchangeably.

(I would have answered your question by saying "No.", but this website won't accept an answer that's less than 200 characters long.)

Is there a way to see the color of cosmic rays the human eye can't see
KATRIN_1 [288]
You would have to use a machine to convert the colors to one visible by humans or become some other species of animal with a larger light spectrum.

Lori wants to send a box of oranges to a friend by mail. The box of oranges cannot exceed a mass of 10.222 Kg. If each orange ha
Sergeu [11.5K]

Explanation:

Given that,

The box of oranges cannot exceed a mass of 10.222 Kg if we are sending to a friend by mail.

The mass of each orange is 198 g

We know that,

1 kg = 1000 g

10.222 kg = 10.222×1000 g

Let there are n number of oranges. So,

n=\dfrac{10.222\times 1000\ g}{198\ g}\\\\n=51.92\approx 52\ \text{oranges}

It means she can send 52 oranges and it is maximum quantity.
