Integrated Concepts How much time is needed for a surgical cauterizer to raise the temperature of 1.00 g of tissue from 37.0°C to 100°C and then boil away 0.500 g of water, if it puts out 2.00 mA at 15.0 kV? Ignore heat transfer to the surroundings.
A Pb wire wound in a tight solenoid of diameter of 4.0 mm is cooled to a temperature of 5.0 K. The wire is connected in series with a 50resistor and a variable source of emf. As the emf is increased, what value does it have when the superconductivity of the wire is destroyed?
Find the average energy of an electron in a Zn wire.
The Hall effect is to be used to find the sign of charge carries in a semiconductor sample. The probe is placed between Own poles of a magnet so that magnetic field Is pointed up. A current is passed through a rectangular sample placed horizizontally. As current is passed through the sample in the east direction, the north side of the sample is found to be at a higher potential than the south side. Decide if the number density of charge carriers is positively or negatively charged.
You are in charge of planning a physics magic show for an open house on your campus. You come up with the following plan for one trick. You will place a sphere on a rough inclined plane of angle , as shown in Figure P28.31, and it will not roll down the incline. Here is the secret that only you know: The sphere is nonconducting, has a mass of 80.0 g, and a radius 20.0 cm. A flat, compact coil of wire with five turns is wrapped tightly around it, with each turn concentric with the sphere. The sphere is placed on the incline so that the coil is parallel to the plane. You establish a uniform magnetic field of 0.350 T vertically upward in the region of the sphere. (a) What current in the coil do you need to make this trick work? (b) You explain the trick to a friend in confidence and he suggests lowering the angle of the plane to make the required current lower. How do you respond? Figure P28.31
If you pick up and shake a piece of metal that has electrons in it free to move as a current, no electrons fall out. Yet if you heat the metal, electrons can be boiled off. Explain both of these facts as they relate to the amount and distribution of energy involved with shaking the object as compared with heating it.
An X-ray tube at a dentists office produces X-rays by striking a metal plate with a beam of electrons in an evacuated tube. The electric field generated in an X-ray tube is approximately 5 106 V/m. What is the energy density stored in this electric field?
Integrated Concepts (a) Redo Exercise 20.25 taking into account the thermal expansion of the tungsten filament. You may assume a thermal expansion coefficient of 12 10-6/°C. (b) By what percentage does your answer differ from that in the example?
Thetha =46.45 and F = 981.3N
A. 14 Nm B. 34 Nm C. 24 Nm
It's saying the 0.0399 is incorrect. The units is g/mol. Thank you for your help.
