1 atm=1.013×103 N/m2 An ideal gas goes through the process shown in the figure. During the B to C the process 345 kJ of energy enter the system by heat. From C to D the process is isothermal. The change in the internal energy experienced by the gas in the BCD process is: none of the other answers is correct 439 kJ (0ks) 345 kJ 251
The tungsten filament of a lightbulb radiates 2.00 W of light. The filament has a surface area of 0.300 mm2 and an emissivity of 0.950. Find the filament's temperature. (The melting point for tungsten is 3683 K and Stephan Boltzmann constant is σ=5.67×10−8 W⋅m−2⋅K−4 ) 3.34×103 K none of the other answers is correct 105 K 378 K
The electric potential in a region in space is given by V(x,y,z)=10x+20xy2−15z V. The the y-component (in N/C ) of the electric field at a point P that has the coordinates (−1,−1,−2)m is: −40 V/m none of the other answers is correct 20 V/m −20 V/m 40 V/m
A variable magnetic field B(t)=(4t−t2) Tesla is directed out of the plane of the page and perpendicular to it, as shown in the figure. A wire loop in the plane of the page has constant area 0.020 m2. What is the value of the induced emf at t=1.00 s, and the direction of the induced current? 0.040 V, clockwise 0.020 V, clockwise 0.020 V, counterclockwise 0.040 V, counterclockwise. none of the other answers is correct
An ideal voltmeter is (incorrectly) inserted into a circuit as shown in the figure. The current in the circuit is: close to 9.0 A nearly zero extremely large close to 0.90 A more information is needed to work out the answer
