1 point 1. A child falls sideways off a sled while sledding on friction-less ice. What
happens to the velocity of the sled? *
a) It increases.
O b) It remains the same.
d) cannot be determined from the information given
c) It decreases.

c) It decreases.

Explanation:

If you treat this as a case of momentum of the sled while sledding on a friction-less ice, then mass and velocity are directly proportional. This means increasing either mass or velocity , the momentum of the object increases proportionally.

In this question, when the child falls sideways off the sled, the mass reduces, the velocity experiences the same causing a decrease in momentum .

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )
