Aboat has a speed of 15 mph in still water. it travels downstream from greentown to glenavon in g hours. it then goes back upstream from glenavon to cambria, which is 2 miles downstream from greentown, in g hours. find the rate of the current.

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2

When does your body conduct current more readily?

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?
