PLEASE HURRY IM BEING TIMED Sphere A is located 120 cm away from sphere B. If sphere A
has a charge of +2.0x10-6 C and sphere B has a charge of -3.6x10-6C,
determine the type of the electric force between the two sphere and the
magnitude of the elecfric force.

Animals respond in various ways to stimuli detected through their senses. some of these responses are stimulated by the presence of danger. which of these animal responses is the best example of a response to an immediate threat? a) a rooster crows every morning at the first sign of light. b) as something approaches an octopus, it shoots a cloud of ink. c) from late fall until spring, bears hibernate to preserve energy. reactivate d) a dog is getting hot in the sunlight, so he moves to a shaded area.

Which of the following are considered noble gases? a. bromine b. neon c. argon d. chlorine

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
