A situation known as ( blank) occurs when astronauts and
their surroundings all accelerate at the same rate.

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?

For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up
