Prove that the potential (r) is a non-decreasing function of r in any spherical system. does the same conclusion hold in an axisymmetric razor-thin disk? if so, prove it; if not, find a counter-example

Heena wants to measure the volume of a ball that is 24 cm across. how should she set up her equation?

Un jugador de beisbol batea un foul recto en el aire.la pelota deja el bate con una rapidez de 120 km/h. en ausencia de resistencia del aire. ? cual sera la rapidez de la pelota cuando la atrape el catcher

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
