By definition, refractive index is the ratio of the velocity of light in vacuum to the velocity of light in a specified medium. The medium here is the liquid. The speed of light through the liquid also depends on the temperature and pressure. At sea level, the liquid is higher in temperature and pressure. So, the speed is gonna be relatively slower because of the movement of atoms. At high altitude, the liquid is at a lower temperature and pressure. The movements of the molecules are lesser, thus, light can move much faster. So, yes, it would be different. The refractive index would be closer to 1 at high altitude, and greater than 1 at sea level.
B.false......absolute magnitude
<span>Measure of the amount of light a star actually gives off.....thats the definition....hop this is helpful</span>

Answer:
a) increases
Explanation:
The increase in temperature causes the particles to move much faster. This in turn effects the collision rate of the particle which causes the chemical reaction. Thus the rate of chemical reaction increases.
So, we conclude that the rate of a chemical reaction is directly related to temperature. With increase in temperature there is an increase in the reaction rate and vice versa.

In the absence of a net force, an object can be at rest or in motion with a constant velocity.
<h3>What is Newton's first law of motion?</h3>
Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that path <u>unless acted upon</u> by an external force.
This law is also called the law of inertia because it depends on mass.
F(net) = ma
when, F(net) = 0, acceleration will be zero and velocity will be constant.
Thus, in the absence of a net force, an object can be at rest or in motion with a constant velocity.
