We wrap a light, nonstretching cable around a 8.00 kg solid cylinder with diameter of 30.0 cm. the cylinder rotates with negligible friction about a stationary horizontal axis. we tie the free end of the cable to a 13.0 kg block and release the block from rest. as the block falls, the cable unwinds without stretching or slipping. how far will the mass have to descend to give the cylinder 510 j of kinetic energy?

In which situation has the independent variable for the experiment been changed? check all that apply. changed from counting the number of duckweed at day 0 and day 14 to counting them every day changed from testing duckweed growth in beakers to testing duckweed growth in large outdoor tanks changed from testing the effect of ph on duckweed growth to testing the effect of light levels on duckweed growth changed from testing the effect of acid ph on duckweed growth to testing the effect of basic ph on duckweed growth

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination.at the turning point, how far is the second student from the destination?
