<h3><u>Answer;</u></h3>
  • Diffraction
  • interference
<h3><u>Explanation;</u></h3>
  • Light may have both <u><em>wave or particle properties.</em></u>
  • <u><em>According to wave theory of light, light behaves like a wave</em></u>. Light is an electromagnetic wave which means it does not require a material medium for transmission. Just like electromagnetic waves light possess both magnetic field and electric fields.
  • <em><u>Light waves displays a transverse type of a wave</u></em> in which it oscillates in a similar direction as that of the wave travel. Due to these characteristics of a wave light can undergo <em><u>diffraction and also interference</u></em>.

Answer:

Diffraction and interference    

Explanation:

Light has a property that it exhibit both wave like and particle like behavior. It is an electromagnetic wave. It do not require any medium for its propagation.

Light shows diffraction and interference both. In interference of light wave, two waves combine to form an interference pattern. While in diffraction of light light bends through the obstacles.

So, the correct options are "diffraction and interference".

Brums [2.3K]

Answer:

a) according to Faraday's law , b) creating a faster movement, placing more turns on coil

Explanation:

a) The voltage is induced in the coil by the relative movement between it and the magnet, therefore according to Faraday's law

           E = - d (B A) / dt

In this case, the magnet is involved, so the value of the magnetic field varies with time, since the number of lines that pass through the loop changes with movement.

This voltage creates a current that charges the battery

b) There are several ways to increase the voltage

* creating a faster movement, can be done by the user

* placing more turns on the coil, must be done by the manufacturer

7. PE=0.5×700n/m×0.9m^2
0.9^2=0.81m
0.5×700×0.81= 283.5J

8. 2000=0.5×(x)×1.5m^2
1.5^2= 0.25
0.25×0.5=0.125
2000=0.125 (x)
2000/0.125=x

Using the given equation you get:

E = 1.99x10^-25 / 9.0x10^-6

Divide 1.99 by 9.0: 1.99/9.0 = 0.22

For the scientific notation, when dividing subtract the two exponents:

25 -6 = 19

So you now have 0.22 x 10^-19

Now you need to change the 0.22 to be in scientific notation form:

2.2 x 10^-20

The answer is B.
