Answer:
3
Explanation:
The mechanical advantage is the ratio of the output force to the input force.
MA = 156 / 52
MA = 3
Sound waves are known as longitudinal waves. Longitudinal waves are also known as compressional waves. These are waves that are made up of a series of compressions and rarefactions. In a longitudinal wave, the motion of the medium is parallel to the direction of the wave. While in transverse waves the motion of the medium is at right angles to the direction of the wave.
I’d love to help, but I can barely understand what you put
Answer:
The smallest integer is n = 4
Explanation:
Using the equation V= Sqrt(F/Linear density)
V= Sqrt(341/0.0120)
V= Sqrt(28416.7)
V= 168.57m/s
Path distance =[ (n +1)/2]lambda
But V= f(Lambda)
n lambda/2 =L
n = f2L/V
n = (20 × 2 × 16.86) / 168.57
n = 4.0007
The smallest integer is n= 4
