2 mA
2. A 75-W light bulb operates with 220 Volts (AC).What is the current through the light bulb?
3. Find the energy of a single photon of frequency 4.5 x 10^14Hz.
4. Shrinking Loop. A circular loop of flexible iron wire has an initial circumference of 163 cm , but its circumference is decreasing at a constant rate of 11.0 cm/s due to a tangential pull on the wire. The loop is in a constant uniform magnetic field of magnitude 0.600 T , which is oriented perpendicular to the plane of the loop. Assume that you are facing the loop and that the magnetic field points into the loop.
Part A Find the magnitude of the emf E induced in the loop after exactly time 9.00 s has passed since the circumference of the loop started to decrease.
Please I need the correct answer!!
5. Three point charges are placed as indicated in the figure below.
a)Make a diagram with the xy-coordinate axes and indicate the direction of forces acting on the charge located at the bottom right corner (i.e., on -3mC charge). Indicate the approximate direction of the net force acting on -3mC charge in the figure.
b) Calculate the x-component of the net force acting on -3mC charge.
c) Calculate the y-component of the net force acting on -3mC charge.
d) Calculate the net force acting on -3mC charge.
e) Determine the direction of the net force acting on -3mC charge (find the angle between the net force and the x-axis).
