You are on top on the school building with a snowball. You see your favorite Physics teacher walking by about 120 m away from you. How fast must you throw the snow ball to hit her (assume you hit her on the foot and you throw the snow ball horizontally from a height of 13.5 m).

Immediately upon reaching its lowest point, a falling pendulum bob has its greatest amount of energy, which is the initial amount of potential energy. a. heat; less than b. heat; more than c. kinetic; less than d. kinetic; more than

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

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.
