Denise is conducting a physics experiment to measure the acceleration of a falling object when it slows down and comes to a stop. she drops a wooden block with a mass od 0.5 kilograms on a sensor on the floor. the sensor measures the force of the impact as 4.9 newtons. whats the acceleration of the wooden block wgen it hits the sensor

How will the system respond to a temperature increase?

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?
