A group of students is observing if a changing magnetic field will produce an electric current. They have a closed circuit containing a coil of wire and a galvanometer to measure current. Which steps would allow student to observe an induced electric current in the circuit? Select two steps that the students can take.

A. Rest the bar magnet in the coil.
B. Spin the bar magnet near the coil.
C. Move the bar magnet through the coil.
D. Add the bar magnet into the circuit with the coil.

The earth remains in orbit around the sun due to the force of gravity. how does the force of gravity exerted by the sun on the earth compare to the force of gravity exerted by the earth on the sun?

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
