What is the frequency of a wave with a wavelength of 0.5 m and speed of 50 m/s

25 m/s

Explanation:

To calculate the speed of a wave, simply multiply its wavelength and its frequency (given that you are provided with the two variables).

This makes sense, since the unit for speed (m/s) matches that of the product of wavelength (m) and frequency (Hz). Keep in mind that one Hz is equivalent to one inverse second (

s

−

1

or

1

s

).

If you multiply m (the unit for wavelength) with

1

s

(the unit for frequency), you will get m/s, the unit for speed.

Now multiply!

.5 m * 50 Hz = 25 m/s

25 m/s is your final answer!

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.

explanation:

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?
