Find the minimum uncertainty in the speed of a red blood cell having mass 1e-13 kg if we know the position of the red blood cell to within 8e-06 m, that is, to about its own size.

An object is moving east, and it’s velocity changes from 65m/s to 25m/s in 10 seconds. which describes the acceleration?

Which boundary is associated with the building of the himalaya mountains? convergent transform divergent hot spot

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
