Conceptual Physics 12
If you exert a horizontal force of 200 N to slide a crate across a factory floor at constant velocity, how much friction is exerted by the floor on the crate? Is the force of friction equal and oppositely directed to your 200-N push? If the force of friction isnt the reaction force to your push, what

Problem 6E Two small spheres spaced 20.0 cm apart have equal charge. How many excess electrons must be present on each sphere if the magnitude of the force of repulsion between them is 4.57 10?21 N?

Probability and Statistical Inference 9
A random sample X1, X2, ... , Xn of size n is taken from a Poisson distribution with a mean of , 0 << . (a) Show that the maximum likelihood estimator for is 6 = X. (b) Let X equal the number of flaws per 100 feet of a used computer tape. Assume that X has a Poisson distribution with a mean of . If
