As the wavelength increases, the frequency select one: a. decreases and energy decreases. b. increases and energy increases. c. decreases and energy increases. d. increases and energy decreases.

Aball is thrown straight up into the air with a speed of 21 m/s. if the ball has a mass of 0.1 kg, how high does the ball go? acceleration due to gravity is g = 9.8 m/s^2. a. 22.5 m b. 20.0 m c. 25.0 m d. 17.5 m

An ionic compound can conduct electricity when a it is dissolved in water b its crystals are ground into powder c it is in solid form d it is heated to just below its melting point

Aball is thrown horizontally from a cliff at 8m/s .in what direction is the ball moving 2s later?
