Answer:

The measurement of the reflected ray will be 110 degrees.

Explanation:

It is given that, a light ray strikes the shiny surface at 70 degrees.

From the given figure, the angle between the incident ray and the surface is 70°. So, the angle between the incident ray and the normal will be 90° - 70° = 20°.

From the laws of reflection, the angle of incidence is equal to the angle of reflection.

So, the angle between the normal and the reflected ray will be 20°. Hence, the measurement of the reflected ray will be 110°.

Hence, the correct option is (B) " 110 degrees ".

Answer:

The magnitude of the electric field is $5.1 \times 10^{11} \frac{N}{C}$

Explanation:

Given:

Charge of electron $q = 1.6 \times 10^{-19}$ C

Separation between two charges $r = 5.3 \times 10^{-11}$ m

For finding the magnitude of the electric field,

$E= \frac{kq}{r^{2} }$

Where $k = 9 \times 10^{9}$

$E = \frac{9 \times 10^{9} \times 1.6 \times 10^{-19} }{(5.3 \times 10^{-11} )^{2} }$

$E = 5.1 \times 10^{11}$ $\frac{N}{C}$

Therefore, the magnitude of the electric field is $5.1 \times 10^{11} \frac{N}{C}$

A student places his hand in front of a plane mirror as shown in

NARA [144]

Answer:

Explanation:

Plane mirrors always form virtual images meaning although the object appears to be in the other side of the mirror the light rays actually originate in front of it. The image is inverted meaning that when you lift your right hand it shows your left hand rising. and with true orientation.
