Ablow-dryer and a vacuum cleaner each operate with a voltage of 120 v. the current rating of the blow-dryer is 10 a, and that of the vacuum cleaner is 4.0 a.
(a) determine the power consumed by the blow-dryer.
w
(b) determine the power consumed by the vacuum (c) determine the ratio of the energy used by the blow-dryer in 11 minutes to the energy used by the vacuum cleaner in one-half hour. ebd / evc =

How have the competing explanations' experiments on atoms affected the development of the atomic model?

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
