What is the wavelength of a wave that has a speed of 11 m/s and a frequency of 53? ? Show your work

0.2075 m

Explanation:

We are given;

Speed; v = 11 m/s

Frequency; f = 53 Hz

The wavelength (λ) is calculated from the equation;

λ = v/f

Thus;

λ = 11/53

λ = 0.2075 m

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

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.
