The table below shows the speed of sound waves from musical sound sources at 20°C. Which conclusion can be made based on the inf
ormation in the table? Wave speed and wavelengths can vary inversely to produce the same frequency. Frequency and wave speed can vary directly to produce the same wavelength. Wavelengths and frequency can vary inversely to produce the same wave speed. Frequency and wavelengths can vary directly to produce the same wave speed. Mark this and return
First we write the corresponding kinematics equations: a = -g v = -g * t + vo y = -g * ((t ^ 2) / 2) + vo * t + yo Substituting the values: y = - (9.81) * (((0.50) ^ 2) / 2) + (19) * (0.50) + (0) = 8.27m answer: the displacement at the time of 0.50s is 8.27m
That's called a prototype, mainly used to save resources of the company or inventor. And used to look for flaws and perfect them to make the product more safe and efficient.
