Answer:
A. 19.8 cm.
Explanation:
The apparent depth of the combination is
As it mentioned that the two clear but non-mixing liquid having depth of 15 cm that placed in a glass container together
Also the refractive indices would be 1.75 and 1.33
Based on the above information
As we know that
Refractive indices = real depth ÷ apparent depth
1.33 ÷ 1.75 = 15 ÷ apparent depth
So, it would be 19.736842 cm
Now the combination of apparent depth would be
= ( 19.736842 + 15) ÷ (1.75)
= 19.8 cm
hence, the correct option is A.
Hello,
To start off, Your answer is Refraction.Refraction is always accompanied by a wavelength. So that is why the wave moves from one medium to another.

The final velocity of the cart at the given mass is 4.36 m/s.
The given parameters;
- <em>mass of the cart, m = 1 kg</em>
- <em>work done on the cart, W = 5 J</em>
- <em>initial velocity of the cart, u = 3 m/s</em>
The distance traveled by the cart is calculated as follows;
Fd = W
mgh = W
The final velocity of the cart is calculated as follows;
Thus, the final velocity of the cart at the given mass is 4.36 m/s.
