If you slosh the water back and forth in a bathtub at the correct frequency, the water rises first at one end and then at the other. Suppose you can make a standing wave in a 179 cm long tub with a frequency of 0.2058 Hz. What is the velocity of the water wave

0.37 m/s

Explanation:

Parameters given:

Wavelength of the wave = 179 cm = 1.79 m

Frequency = 0.2058 Hz

Speed of a wave is given as:

Speed = wavelength * frequency

Speed = 1.79 * 0.2058

Speed = 0.37 m/s

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

i think the answer is tomato juice? not entirely sure though
