An opposite a positive charge qi = +1 cm, y2 0. for q = 2.00 c: charge q2 -q is at x2 a (30%) show in a vector diagram the direction of the net electric field e at the point p located at x = 2.00 cm, y = 1.00 cm find the distances and directions needed to calculate e. b (70%) find the magnitude of e at that point 6 2 x10 y -6 p 1 2 p m -c

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

Describe cytokinesis in plants and animals. in animals: in plants.

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
