Light enters air from water. The angle of refraction will be A. less than the angle of incidence. B. greater than or equal to th
Rina8888 [55]

Answer:

E. greater than the angle of incidence.

Explanation:

Snell's law states that:

n_i sin \theta_i = n_r sin \theta_r (1)

where

n_i, n_r are the refractive index of the first and second medium

\theta_i, \theta_r are the angle of incidence and refraction, respectively

For light moving from water to air, we have:

n_i = 1.33 (index of refraction of water)

n_r = 1.00 (index of refraction of air)

Substituting into (1) and re-arranging the equation, we get

\sin \theta_r = \frac{n_i}{n_r} sin \theta_i = 1.33 sin \theta_i

which means that

\theta_r > \theta_i

so, the correct answer is

E. greater than the angle of incidence.

If the maximum tension in the simulation is 10.0 N, what is the linear mass density (m/L) of the string
vovikov84 [41]

Complete Question

The speed of a transverse wave on a string of length L and mass m under T is given by the formula

     v=\sqrt{\frac{T}{(m/l)}}

If the maximum tension in the simulation is 10.0 N, what is the linear mass density (m/L) of the string

Answer:

(m/l)=\frac{10}{V^2}

Explanation:

From the question we are told that

Speed of a transverse wave given by

v=\sqrt{\frac{T}{(m/l)}}

Maximum Tension is T=10.0N

Generally making (m/l) subject from the equation mathematically we have

v=\sqrt{\frac{T}{(m/l)}}

v^2=\frac{T}{(m/l)}

(m/l)=\frac{T}{V^2}

(m/l)=\frac{10}{V^2}

Therefore the Linear mass in terms of Velocity is given by

(m/l)=\frac{10}{V^2}

Iteru [2.4K]

Answer:

x=65.55m

Explanation:

Let x be the distance to the shore

From trigonometry properties:

tan(40^{o} )=\frac{55m}{x} \\x=\frac{55m}{tan(40^{o} )} \\x=65.55m
