A500 turn circular-loop coil 16.0 cm in diameter is initially aligned so that its axis is parallel to the earth's magnetic field. in 2.89 ms, the coil is flipped so that its axis is perpendicular to the earth's magnetic field. if an average voltage of 0.170 v is thereby induced in the coil, what is the value of the earth's magnetic field at that location? bearth = 1 µt

The air that we breath is made mostly of which gaseous molecule

The star betelgeuse is about 600 light-years away. if it explodes tonight, a. we'll know because debris from the explosion will rain down on us from space. b. we'll know it immediately because it will be brighter than the full moon in the sky. c. we won't know about it until 600 years from now. d. none of the above.

An engine undergoes a cycle as shown in the diagram. during a complete cycle the work done by the gas is 28.5×103 j and the energy transferred thermally out is 99.4×103 j. there are 1.5×1024 gas molecules and they have three active degrees of freedom. 6. (6 pts) during which process(es) is energy transferred thermally into the gas? a. 1→2 b. 2→3 c. 4→1 d. 1→2 and 4→1 e. none of the above
