Hot spots 4. A 955 kg car is moving at 25 m/s. The car brakes and comes to a stop. The
brakes are composed of 23.5 kg of iron which absorb 50.0% of the car's kinetic
energy. What is the increase in the temperature of the brakes? The Specific
Heat Capacity of iron is 470 J/(kg * Cº).

Study the diagram showing the range of temperature in the earth’s layers. which temperature most likely corresponds to the asthenosphere? 1,613°c 2,521°c 3,628°c 6,217°c

What is a good example of instantaneous speed

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.
