The wavelength of a sound in a certain material is 18 cm the frequency of a wave is 2000 Hy calculate the speed of the wave

Speed = 360m/s

Explanation:

Given the following data;

Wavelength = 18cm to meters = 18/100 = 0.18m

Frequency = 2000Hz

To find the speed;

Speed = frequency * wavelength

Speed = 2000 * 0.18

Speed = 360m/s

Therefore, the speed of the wave is 360 meters per seconds.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
