Is this argument valid or invalid? Why? What did you consider when determining whether this argument uses proper reasoning? If students earn college degrees, they tend to make more money. Chris earned a college degree.

Calculate the buoyant force (in N) on a 1.0 m^3 chunk of brass submerged in a bath of mercury.

A man wishes to pull a crate 15m across a rough floor by exerting a force of 100 N. The coefficient of kinetic friction is 0.25. For the man to do the least work, the angle between the force and the horizontal should be: A. 0 B. 14? C. 43? D. 66? E.

Contrast balanced and unbalanced forces.

A wave will travel only as long as it has energy

a box sliding on a frictionless surface when it suddenly begins to rain heavily. if the downpour of rainfall falls vertically into the box, gradually filling it, what would happen to the speed of the box

Which would fall with a greater acceleration in a vacuum-a leaf or a stone?

A force acts on a 5kg object at rest. How fast will the object accelerate on a frictionless surface? A.) 4 m/s^2 B.) 15 m/s^2 C.) 25 m/s^2 D.) 100 m/s^2
