The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

Kathy tests her new sports car by racing with stan, an experienced racer. both start from rest, but kathy leaves the starting line 1.00 s after stan does. stan moves with a constant acceleration of 3.9 m/s2 while kathy maintains an acceleration of 4.95 m/s^2. a) find the time at which kathy overtakes stan. b) find the distance she travels before she meets stan. c) find the speeds of both cars at the instant she overtakes him. (of kathy and stan)

Consider the periodic signal x(t) = cos(2�0t) + 2 cos(�0t), −∞ < t < ∞, and�0 = π. the frequencies of the two sinusoids are said to be harmonically related. (a) determine the period t0 of x(t). compute the power px of x(t) and verify that the power px is the sum of the power p1 of x1(t) = cos(2πt) and the power p2 of x2(t) = 2cos(πt). (b) suppose that y(t) = cos(t) + cos(πt), where the frequencies are not harmonically related. find out whether y(t) is periodic or not. indicate how you would fnd the power py of y(t). would py = p 1 + p2 where p1 is t
