A sound wave has a speed of 345 m/s and a wavelength of 4.15 meters. What is the frequency of this wave?
Debora [2.8K]

Answer:

83 hertz

OPTION A

Explanation:

wavelength =  \frac{speed}{frequency}

Given

wavelength=4.15m

speed=345 m/s

frequency =  \frac{speed}{wavelength} =  \frac{345}{4.15}

frequency = 83 \: hertz

An 80 N force causes a spring to compress 0.15 m. What is the spring constant? What is the potential energy of the spring?
Anni [7]
Force = -kx
80N=0.15m * -k
K=-80/0.15=533.333. Spring constant
Energy=1/2kx^2
1/2*(-80/0.15)*80^2=Energy
