Aphysics student gets her car stuck in a snow drift. as shown below, she attaches one end of a stout inextensible rope to the bumper of her car and the other end (with a small amount of slack) to a nearby tree at about the same height as where the rope is attached to the bumper. if she then leans on the rope applying a horizontal force of 456 n, determine the force on the car.

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
