Answer:
8672
Explanation:
multiply the length value by 100
Answer b protons and electrons
Work done = force * distance
work done = 200 * 20
work done = 4000J
Answer:
Wavelength of the sound wave that reaches your ear is 1.15 m
Explanation:
The speed of the wave in string is

where T= 200 N is tension in the string ,
=1.0 g/m is the linear mass density


Wavelength of the wave in the string is

The frequency is
