What happens after sound waves reach the ear drum? A. The mechanical energy of the sound is turned into electrochemical energy of the nerve.
B. They are converted to mechanical waves that travel through the bones of the middle ear.
C. They are detected by the auditory nerve, which sends information about the sound to the brain.
D. The fluid in the cochlea moves back and forth, disrupting the hair cells in the ear.

Which statement is true? a. kepler's laws apply only to the motion of earth. b. kepler's laws can be used to predict eclipses. c. kepler's laws are true for a central force that is directly proportional to distance. d. kepler's laws can be deduced from newton's laws of motion and gravity.

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
