The driver of a car traveling at 21 m/s applies the brakes and decelerates at the rate of -3.8 m/s. (a) How long does it take to bring the car to a stop?

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?

The radius of a sphere is increasing at a rate of 9 cm/ sec. find the radius of the sphere when the volume and the radius of the sphere are increasing at the same numerical rate.
