The speed of the wave with the given frequency and wavelength is 1.2m/s.
Given the data in the question;
- Wavelength of the wave;

- Frequency;

- Speed of the wave;

<h3>
Wavelength</h3>
Wavelength is the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.
It is expressed as;

Where v is velocity/speed and f is frequency.
Now, we can easily get the speed of the wave by substituting our given values into the expression above.

Therefore, the speed of the wave with the given frequency and wavelength is 1.2m/s.

the answer is the first one because neutrons and protons are in the middle of an atom. plz give me brainliest
Answer:
Explanation:
decrease in energy of the transferred charge
= Voltage x charge
= 2.86 x 10⁹ x 23.1
= 66.067 x 10⁹ J
the final speed of the automobile be V
1/2 m v² = 66.067 x 10⁹
v² = 66.067 x 10⁹ x 2 / 1519
= .08698 x10⁹
= 87 x 10⁶
v = 9.32 x 10³ m / s
