The purpose is to refresh your memory on force diagrams and Newton's laws and to generate ideas about fluids. Activity 1 Suppose that you carefully inject some oil into the middle of a beaker of water that is at rest on a table. As you may know from experience, the oil subsequently rises to the top of the water. Individually or with a partner, as directed by your instructor, do the following, in order to explain why the oil rises:...

Activity 2 You have made some conclusions about the water pressure at various points int water. Do the following to test these conclusions: he beaker of a. Consider a container of water at rest. b. Imagine a cylindrical column of the water from the top of the water to a depth h below the top of the water; assume that the cross-sectional area is A. Draw all forces acting c the column of water. You may assume that the forces...

A: Applying Newton's laws to interacting objects which velocity are moving with a constant A factory worker is pushing two touching crates across the floor. The crates move at a constant velocity since there is kinetic friction between each crate and the floor. You may assume that the coefficient of kinetic friction between each crate and the floor is the same. 3M M on M to that on 3M. Explain your ans Compare the net force (magnitude and direction) 1....

Mech Newton's second and third laws HW-40 2. Two crates, A and B, are in an elevator as shown. The mass of crate A is Cable greater than the mass of crate B. a. The elevator moves downward at constant speed. Elevator i. How does the acceleration of crate A compare to that of crate B? Explain. A MA Constant ii. In the spaces provided below, draw and label separate free-body speed diagrams for the crates. Free-body diagram for Free-body...

1. Starting with one of Newton's laws and your free body
diagram, derive an expression for the normal force exerted on the
block by floor.
- Assess you answer in the following way: If you
let \(\theta\) = 0, what does your
solution predict for the normal force? Does this make physical
sense?
2. Starting with one of Newton's laws and your free body
diagram, derive an expression for the coefficient of kinetic
friction \(\mu_{k}\) between the
block and the...

You have learned that Newton's 3rd Law states that when one mass exerts a force on another mass, there will be equal but opposite forces between then. If you recall, this is what allows us to jump UP off the ground, even though we press DOWN with our legs into the Earth. But... what about the following scenario? A tractor is hooked to a trailer full of horses. Once the tractor begins pulling the trailer forward on a level surface,...

understanding newton's law 1. An object cannot remain at rest unless which of the following holds? a. The net force acting on it is zero. b. The net force acting on it is constant and nonzero. c. There are no forces at all acting on it. d. There is only one force acting on it. which one is the answer? there can be more than one answer.... 2. If a block is moving to the left at a constant velocity,...
