Officials are looking into three different ski accidents. The accidents happened when three skiers (all with the same mass) were skiing across flat, snowy ground. They were each bumped by another skier, but not all from the same direction. These skiers changed speed as a result of being bumped. Use the information in the diagram to answer. Which skier(s) experienced the strongest force when bumped? How do you know? A. The skiers in the yellow and purple sweaters; they both gained the same force as they sped up, but the skier in the red sweater lost force and slowed down.

B. The skier in the yellow sweater experienced the strongest force because he has the fastest ending speed.

C. All three skiers experienced the same strength force because they changed speed by the same amount.

D. The skier in the red sweater because it takes a stronger force to slow something down than to speed it up.

b would be the right answer

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
