Suppose that we repeat the experiment shown in the video, but we replace one of the cylinders with a cylinder that has twice the radius (and use larger containers of water). If the height of the original cylinder is \rm h, how deeply must we submerge the new cylinder to get th...

A key falls from a bridge that is 45 m above the water. The key falls straight down and lands in a model boat traveling at a constant velocity of 3.5 m/s. Calculate the distance the boat was from the point of impact when the key was released. Answer d= 10.6 m

A ball is dropped from the top of a building. The balls fall 3 times farther during its last second of freefall than it did during its third second of freefall. The ball fell 4.9 meters during its first second, how tall is the building and how much time is the ball in the air?...

Evaluate the integral using any method: (Integral)sec^3x/tanx dx I started it out and got secx(1tan^2x)/tanx. I know I just have to continue simplifying and finding the integral, but I'm stuck on the next couple of steps. Also, I have another question witht he same directi...

just get the molar mass and use multiplication by one, meaning it would be mol/1 x grams(from molar mass)/moles(1)of the compound.
