Ascientist hypothesizes that the temperature at which an alligator's egg is incubated will determine whether the alligator will be male or female. the independent variable is (a) the temperature (b) the gender of the alligator (c) the incubator (d) the male alligators.

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?

The electric field inside a cell membrane is 8.0mn/c. what's the force on a singly charged ion in this field?
