Answer:

When reviewing the results, the correct one is C

Explanation:

The right hand rule is widely useful in knowing the direction of force in a maganto field,

The ruler sets the thumb in the direction of the positive particle, the fingers extended in the direction of the magnetic field, and the palm in the direction of the force.

Let's apply this to our exercise.

The thumb that is the speed goes in the negative direction of the axis,

The two extended that the magnetic field look negative x,

The span points entered the dear sheet the negative the Z axis

When reviewing the results, the correct one is C

Determine e when I = 0.50 A and R = 12 W.

sammy [17]

Answer:

The correct answer is "24 V".

Explanation:

The given values are:

Current,

I = 0.50 A

Resistance,

R = 12 W

As we know,

⇒ $I = 0.5\times (\frac{E}{2R})$

On substituting the given values, we get

⇒ $0.5= (\frac{E}{4\times 12} )$

⇒ $0.5= (\frac{E}{48} )$

⇒ $E=24 \ V$

Which ray diagram correctly illustrates what happens when light is incident from the air onto a flat glass surface? The dotted l

prohojiy [21]

Answer:

When light incident at angle more than critical angle then whole beam of light will get reflected at same angle into the same medium

So correct answer is

Option D

Explanation:

Critical angle is the maximum angle of incidence for which light shows the phenomenon of refraction of light

Here light bends at 90 degree angle when light incident at critical angle

Now if the incident light is more than the critical angle then light will follow the rules of reflection and all light rays will get reflected at same angle as that of angle of incidence

So here we can say that correct answer is

Option D

A laser beam enters a 16.5 cm thick glass window at an angle of 58.0° from the normal. The index of refraction of the glass is 1

ivann1987 [24]

Answer:

using Snells law

Oi = angle of incidence = 58.0°

ni = index of refraction of air = 1.0003

nr = index of refraction of glass = 1.47

c = speed of light in vacuum = 3 x 10^8 m/s
