a sample of gas has a volume of 140000cm^3 at a pressure of 8.5 atm. if the pressure was lowered to 4.7 atm, what would the pressure be

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

What was the first instrument to ever record an earthquake?

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
