Answer from: wiredq2049

Speed=0.3*100=30m/s

speed=0.1*50=5m/s

frequency=20/0,5=40HZ

frequency=80/0.2=400HZ

frequency=120/0.4=300HZ

wavelength=340/440=0.77m

wavelength=340/880=0.39m

wavelength=250/400=0.63m

speed=2*50=100m/s

speed=0.5*100=50m/s

frequency = 20/0,5 = 40Hz

What is the frequency of a wave that has a wave speed of 80 m/s and a wavelength of 0.20 m?

frequency = 80/0.2 = 400Hz

What is the frequency of a wave that has a wave speed of 120 m/s and a wavelength of 0.40 m?

frequency = 120/0.4 = 300Hz

What is the wavelength of a sound wave that has a speed of 340 m/s and a frequency of 440 Hz?

wavelength = 340/440 = 0.7727m

What is the wavelength of a sound wave that has a speed of 340 m/s and a frequency of 880 Hz?

wavelength = 340/880 = 0.3864m

What is the wavelength of a sound wave that has a speed of 250 m/s and a frequency of 400 Hz?

wavelength = 250/400 = 0.625m

What is the wave speed of a wave that has a frequency of 50 Hz and a wavelength of 2.0 m?

speed = 2*50 = 100m/s

What is the wave speed of a wave that has a frequency of 100 Hz and a wavelength of 0.50 m?
speed = 0.5*100 = 50m/s

Answer from: Quest

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

Look at the pendulum diagram between which points does the pendulum’s potential energy increase most

Answer from: Quest

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow
