Part 1:

a strong lightning bolt transfers about 22.65 c to earth. how many electrons are transferred? the elemental charge is 1.602 x 10^ -19 c.

part 2:

the lightning bolt discharge lasts one millisecond. what is the average current flowing from the cloud to the ground? answer in units of a.

Brutus, the dog, is pulling a bone to the left with a force of 20 n. lassie, another dog, is pulling a bone to the right with a force of 18n. what is the net force? a. b. c.

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
