No, options are given but I believe the answer would be
In a water cycle Solid state of matter has the particles closest together.
Answer:
The bending of light as it passes from one medium to another is called refraction. The angle and wavelength at which the light enters a substance and the density of that substance determine how much the light is refracted. The bending occurs because light travels more slowly in a denser medium.
hope this helped :))
Answer:
Explanation: When a body covers unequal distances in equal intervals of time in a specified direction, the body is said to be moving with a variable velocity. Example: A rotating fan at a constant speed has variable velocity, because of continuous change in direction.
Explanation:
It is given that,
A particle starts from rest and has an acceleration function as :
(a) Since, 
v = velocity
(b) 
x = position
(c) Velocity function is given by :
t = 1 seconds
So, at t = 1 second the velocity of the particle is zero.
