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.
Barium fluoride(BaF2) is a chemical compound of barium and fluorine and is a salt. It is a solid which can be a transparent crystal.
A speed does not involve the element of direction.
that is a prediction for a future experiment based on previous experiment results.
(guessing what will happen in the future experiment based on the results of the past experiments)
The focal length would likely decrease as the refractive index and the increase when the curvature radius of the lens increases. The decrease in focal length happens since a higher index of refraction would signify that the rays of the sun striking to an object would tend to bend more.
