You have designed a rocket to be used to sample the local atmosphere for pollution. it is fired vertically with a constant upward acceleration of 19 m/s2. after 20 s, the engine shuts off and the rocket continues rising (in freefall) for a while. (neglect any effects due to air resistance.) the rocket eventually stops rising and then falls back to the ground. you want to get a sample of air that is 14 km above the ground. (a) what is the highest point your rocket reaches?

Six solutions are made, each with a y concentration of 1.0 μm and varying concentrations of ab as shown below. based on the concentrations, rank the solutions in decreasing order of reaction rate.

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o

Aleaky 10-kg bucket is lifted from the ground to a height of 15 m at a constant speed with a rope that weighs 0.7 kg/m. initially the bucket contains 45 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 15-m level. find the work done. (use 9.8 m/s2 for g.) show how to approximate the required work by a riemann sum. (let x be the height in meters above the ground. enter xi* as xi.) lim n → ∞ n (9.8)(45−3 xi) i = 1 δx express the work as an integral. 0 dx evaluate the integral. (round your answer to the nearest integer.) j
