If two waves are traveling at the same speed, which statement will be true about their wavelengths? 1.the wave with higher frequency will have shorter wavelength. 2.the wave with lower frequency will have shorter wavelength.
3.the wave with higher frequency will have longer wavelength.

What is the coefficient of kinetic friction μk between the block and the tabletop?

What’s #16 asking me and how do i solve it?

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
