A beam of light traveling through a liquid (of index of refraction n1 = 1.47) is incident on a surface at an angle of θ1 = 49° w

dsp73

Answer:

a) n2=(n1sin1)(sin2)

b) 1.18

c) 201081632.7m/s

d) 254237288.1m/s

Explanation:

a) We can calculate the index of refraction of the second material by using the Snell's law:

$n_1sin\theta_1=n_2sin\theta_2$

$n_2=\frac{n_1sin\theta_1}{sin\theta_2}$

b) By replacing in the equation of a) we obtain:

$n_2=\frac{(1,47)sin49\°}{sin69.5\°}=1.18$

c) light velocity in the medium is given by:

$v=\frac{c}{n_1}=\frac{3*10^{8}m/s}{1.47}=204081632.7\frac{m}{s}$

$v=\frac{c}{n_2}=\frac{3*10^{8}m/s}{1.18}=254237288.1\frac{m}{s}$

hope this helps!!

Calculate the power provided by a 12 volt car battery with a rating of 350 amperes.

mamaluj [8]

Answer:

Option D

4200 W

Explanation:

Power, P is also given as the product of voltage and current, expressed as P=VI

Here, P is power, V is voltage in the xircuit and I is current theough voltage.

Taking 12 V for voltage across and 350A for current across circuit then power will be

P=350*12=4200 W

Therefore, option D is correct.
