Answer:

Angle of refraction in the glass is 32 degrees

Explanation:

It is given that,

Maurice directs a beam of light on a sheet of glass at an angle, θ₁ = 51°

The refractive index of the glass is, n₂ = 1.46

We know that the refractive index of the air is, n₁ = 1

We have to find angle of refraction in glass i.e. θ₂

According to Snell's law :

\dfrac{n_1}{n_2}=\dfrac{sin\ \theta_2}{sin\ \theta_1}

Putting all the values we get :

\dfrac{1}{1.46}=\dfrac{sin\ \theta_2}{sin51}  

\theta_2=sin^{-1}(\dfrac{sin(51)}{1.46})

\theta_2=32\ ^0

Hence, the correct option is (c) " 32 degrees ".

Mary pushes a crate by applying force of 18 newtons. Unable to push it alone, she gets help from her friend, Anne. Together they
maw [93]
 <span>This problem is relatively simple, in order to solve this problem the only formula you need to know is the formula for friction, which is: 

Ff = UsN 

where Us is the coefficient of static friction and N is the normal force. 

In order to get the crate moving you must first apply enough force to overcome the static friction: 

Fapplied = Ff 

Since Fapplied = 43 Newtons: 

Fapplied = Ff = 43 = UsN 

and it was given that Us = 0.11, so all you have to do is isolate N by dividing both sides by 0.11 

43/0.11 = N = 390.9 which is approximately 391 or C. 3.9x10^2</span>
