1. What is the wave speed of a wave that has a frequency of 50 Hz and a wavelength of 0.20 m?

2. What is the frequency of a wave that has a wave speed of 100 m/s and a wavelength of 0.20 m?

3. What is the wavelength of a sound wave that has a speed of 340 m/s and a frequency of 420 Hz? (Round your answer to the nearest hundredth)

4. What is the wavelength of a sound wave that has a speed of 270 m/s and a frequency of 400 Hz?

5. What is the wave speed of a wave that has a frequency of 100 Hz and a wavelength of 0.25 m?

1. 10m/so

2. 500Hz

3. 0.81m

4. 0.675m

5. 25m/s

Explanation:

Speed = wavelength * frequency

1. Speed = 50×0.2 = 10m/s

2. Frequency = 100/0.2 = 500Hz

3. Wavelength = 340/420 = 0.81m

4. Wavelength = 270/400 =0.675m

5. Speed = 100×0.25 = 25m/s

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
