Light passes from a material A, which has an index of refraction of 4/3, into material B, which has an index of refraction of 5/

katrin2010 [14]

Answer:

(b) 32.2°

Explanation:

Using Snell's law as:

$n_i\times {sin\theta_i}={n_r}\times{sin\theta_r}$

Where,

${\theta_i}$ is the angle of incidence ( 30.0° )

${\theta_r}$ is the angle of refraction ( ? )

${n_r}$ is the refractive index of the refraction medium (Material B, n=5 / 4)

${n_i}$ is the refractive index of the incidence medium (Material A, n=4 / 3)

Hence,

${\frac {4}{3}}\times {sin30.0^0}={\frac {5}{4}}\times{sin\theta_r}$

Angle of refraction = $sin^{-1}0.5333$ = 32.2°

And electromagnet is in temporary magnet made by Coiling wire around an iron core which becomes a magnet win and electric curren

Bad White [126]

Answer:

We can increase the strength by increasing current in the wire or increasing the number of turns of the coil around an iron core .

Explanation:

The magnetic strength due to current carrying conductor carrying current I and having N number of turns is given by

B = $\mu _{0}\times N\times I$

$\mu_{O}$ is vacuum permeability .and its value is equal to $4\pi\times10^{-7} \frac{H}{m}$

.so from the above equation we can see that magnetic strength is directly proportional to the current through wire and no. of turns .

Identify the arrows that show input force

satela [25.4K]

The answer is that the reverse arrows pointing to the left needs to release energy. The molecules in the gas state are free such that they can travel from one point to another easily. They have the highest amount of energy. So, if you want the molecules to come closer together, you need to remove the energy to keep them in place. Therefore, the arrows pointing to the right require removal of energy.

A new planet is discovered that has twice the Earth's mass and twice the Earth's radius. On the surface of this new planet a per

kirza4 [7]

Answer:

option B

Explanation:

Radius of new planet,R' = 2R

Mass of the earth, M' = 2 M

R and M is the Radius and Mass of the earth.

Weight of the person on earth = 500 N

Weight of the person in the new planet = ?

We know acceleration due to gravity is calculated by using formula

$g = \dfrac{GM}{R^2}$

now, acceleration due to gravity on the new planet

$g' = \dfrac{GM'}{R'^2}$

$g' = \dfrac{G(2M)}{(2R)^2}$

$g' =\dfrac{1}{2} \dfrac{GM}{R^2}$

$g' =\dfrac{g}{2}$

here acceleration due to gravity is half in new planet, so weight will also be half on the new planet.

Weight on the new plane is equal to $\dfrac{500}{2}$ = 250 N

correct answer is option B

I put +40 points!!!

Aleonysh [2.5K]

Answer:We can solve this using the Law of Conservation of Momentum. If both marbles are in our system, the initial momentum should equal the final momentum.

The initial momentum can be solved for as so:

* + =

(0.06)(0.7) + (0.03)(0) = 0.042 [kg * m/s]

So if the system has an initial momentum of 0.042, it should have the same final momentum.

(0.06)(-0.2) + (0.03)() = 0.042

(0.03)() = 0.54

() = 18 [m/s]
