Katie designed an experiment using a paint roller pan, sand, and water. the steps of the experiment are listed below. 1. put 3 inches of moist sand on a paint roller pan. 2.make a beach by scooping the sand towards the higher portion of the pan. 3.put some soil with very small plants growing on it on the sand. 4.pour water into the deeper end of the pan. 5.move the roller pan to create wave like motion in the water. 6.observe how the sand and plants are displaced by the waves. katie’s model most likely represents the interactions between the a. atmosphere, ocean and cryosphere b. geosphere, ocean, and biosphere c. atmosphere, ocean, and biosphere d. cryosphere, biosphere, and ocean

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
