The water of a 14' x 48' metal frame pool can drain from the pool through an opening at the side of the pool. the opening is about h = 1.08 m below the water level. the capacity of the pool is v= 3760 gallons, the pool can be drained in t 9.9 mins. po is the pressure of the atmosphere. e is the density of the water

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?

If forces acting on an object are unbalanced. true or false
