Because quantum mechanics is physics that describes the interactions of very small objects (i. e. molecules, atoms, and electrons), this week you will need to know how to multiply very small numbers. remember that scientific notation writes very small or large number in terms of powers of 10. for example, .0008 can be written in scientific notation as 8 x 10-4 or as 8e-4. the power of 10 (-4 in this case) tells you to take the number 8.0 and move the decimal 4 places to the left giving us .0008. which is a correct representation of .000025 in scientific notation?

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
