Calculate the speed of a proton in (m/s) that is accelerated from rest through an electric potential difference of 119 V. m e^ - =9.11*10^ -31 kg; m e^ + =1.66*10^ -27 kg; 9 e^ + =q e^ - =1.6*10^ -19 c

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

Awoman holds a book by placing it between her hands such that she presses at right angles to the front and back covers. the book has a mass of m = 1.8 kg and the coefficient of static friction between her hand and the book is μs = 0.67. no attempt 50% part (a) what is the weight of the book, fgb in newtons?

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.)
