Clara made a chart to summarize some of the evidence that supports the big bang theory. which best describes clara’s error? during redshift, the light source and observer move closer together, not farther apart. the cmb is blue-shifted, not red-shifted, to the microwave region. the temperature of the cmb is cooler, not hotter, than at the time of the big bang. the redshift indicates approaching, not receding, galaxies.

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?

Does current flow through or across a resistor?

What is the difference between mass density and weight density?
