A glass plate whose index of refraction is 1.66 is immersed in a liquid. The surface of the glass is inclined at an angle of 44º
Anna35 [415]

Answer:

C. 1.15

Explanation:

The formula for the critical angle is:

{sin\theta_{critical}}=\frac {n_r}{n_i}

Where,  

{\theta_{critical}} is the critical angle

n_r is the refractive index of the refractive medium.  ( Alcohol , ? )

n_i is the refractive index of the incident medium.  ( Glass, 1.66 )

<u>Critical angle =  44º</u>

Applying in the formula as:

{sin\theta_{critical}}=\frac {1}{1.523}

{sin\ 44^0}=\frac {n_r}{1.66}

{n_r}=1.15

How does the structure of the stigma aid in pollination
natali 33 [55]
<span>Pollination is the process by which pollen is transferred to the female part of a plant. The stigma is the central part of the flower, that is supported by a style and is part of the female reproductive organ within plants. Its structure is optimised to promote pollination by having hairs, sticky surfaces and three-dimensional sculptures that capture and trap pollen.</span>

What type of force cause an object to accelerate??
Olin [163]
ANY force causes an object to accelerate, just as long as there are not
some other forces on the object that cancel out the first one.

Are you looking for the answer ... an "UNBALANCED" force ?
That's a very poor way to describe it, because there's no such thing
as a balanced or unbalanced force.  The thing that's balanced or
unbalanced is a GROUP of forces, not a single force.
