A wave is traveling with a wavelength of 200 m at a frequency of 20 Hz what is the speed of the wave

The speed of the wave is .

Explanation:

We are given that a wave has a wavelength of 200 meters and a frequency of 20 Hz.

The equation that relates the speed, wavelength, and frequency is

Luckily, instead of having to make a calculation, the speed of a wave is a constant. This is the speed of light constant, where .

Therefore, instead of having to solve, we can now determine that the speed of the wave is .

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
