how much time is needed for a car to accelerate from 6.5 m/s to a speed of 22 m/s if the acceleration is 3.0 m/s/s?

If you put one whole and put it next to 1/5 then it would be bigger,so it would be 1 whole and 1/5 is greater than 1/4.

find the geometric mean of 275 and 11 275/x=x/11 x^2= 3025 x=sq rt 3025 now I'm not sure what to do.

If i have three resistors in parallel and series, then the first resistor (series) and the second resistor (parallel) should have the same average of the total voltage? is this true? i think it should

Can someone explain how you get the answer b/15. Given the proportion a/b=8/15, what ratio completes the equivalent proportion a/8=?/?. I'm not sure if there is an equation or step you use to get the answer.

suppose that resting on your non-conducting desktop is a tiny piece of paper (m=0.08g) that has a charge of 4x10^-10C. You bring your comb 3 cm away from it and the paper jumps up to the comb. Give an approximate value for the charge of the comb. Does the comb carry an excess ...
