Answer:
below
Explanation:
Ice melts, meaning it has a watery layer upon its surface. This allows things to be moving like they are on a liquid but it has the solidity of a solid. The thin metal of the ice skates also decrease the surface area meaning it exerts more force but in turn, it allows you to move faster and further reduces friction.
Answer:

Explanation:
From the question we are told that:
Water index of refraction 
Glass index of refraction 
Generally the equation for Brewster's law is mathematically given by



Therefore Angle of incident to plane \mu (normal at 90 degree to the surface)



Explanation:
Filtration is used to separate mixtures containing materials of relative size differences.
They are typically used to separate solid-liquid mixtures.
- The filter system must have been used in the experiment to separate filtrates and collect them in the reaction.
- The liquid passes through the filter and leaves behind the solute or suspension in the filter.
- The fluid that passes through the filter is the filtrate.
- This is a separation technique used for most solid - liquid mixtures in which the solid is not soluble.
- An example is sand and water mixture.
