A 1200 kg bus moving at 20 m/s takes a turn around a circle with a radius of 20 m. Determine the net force acting upon the bus.

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )

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.
