In Europe, the standard voltage is 240 V (rms), AC, and 50 cycles/s. Suppose you take your 5.00 W electric razor to Rome and plug it into the receptacle (with an adapter to fit the receptacle but not to change the voltage).
(a) What power will it draw in Rome?
(b) What rms current will run through the razor in the United States and in Rome? Is the razor in danger of being damaged by using it in Rome without a voltage adapter?
(c) If you want to use the razor in Rome without damaging it, what type of transformer would you need? Be as quantitative as you can.
(d) What is the resistance of your razor?
An electron moves in the positive x-direction a distance of 2.31 m in 2.85·10-8 s, bounces off a moving proton, and then moves in the opposite direction a distance of 1.53 m in 3.33·10-8 s.
The resolving power of a microscope depends on the wavelength used. If you wanted to "see" an atom, a wavelength of approximately 1 × 10-11 m would be required.
An ambulance with a siren emitting a whine at 1200 Hz overtakes and passes a cyclist pedaling a bike at 2.44 m/s, How fast is the ambulance moving
Two circular disks spaced 0.50 mm apart form a parallel-plate capacitor. Transferring 1.50 ×109electrons from one disk to the other causes the electric field strength to be 2.90 ×105N/C
A glass rod that has been charged to + 17.0nC touches a metal sphere. Afterward, the rod's charge is + 9.0nC
Two particles, with charges of q1 = 60.0nC and q2 = 60.0nC, are placed at the points with coordinates (0, 12.00 cm) and (0, 12.00 cm). A particle with charge q3 = 30.0 nC is located at the origin.(a) Find the electric potential energy of the confi..

An electron moves at a speed of 15000 m/s in a circular path of radius 2.2 cm. Find the strength of the magnetic field inside the solieod
In the figure particles with charges q1 = +5e and q2 = -13e are fixed in place with a separation of d = 21.3 cm, what are the finite positive and negative values of x
A 60 kg woman stands on a very light, rigid board that rests on the bathroom scale at each end. She is 1.5m away from one side and 0.5 m from the other.
At a dock, a crane lifts a 1200 kg container 30 m, swings it out over the deck of a frieghter, and lowers the container into the hold of the freighter, which is 10 m below the level of the dock. The acceleration of gravity is 9.8 m/s2. Neglect fri..
Find out the magnitude of the acceleration (in m/s2) for an alpha particle in a uniform electric field with a magnitude of 100 N/C
