Answer:
The speed of a wave would be 18 with a wavelength of 2 m and a frequency of 9 Hz.
Answer: 25 kg
Identify the given information.
f = 250 N
a = 10 m/s^2
Choose which formula you should use. In this case, you are finding the mass.
The formula for force is f = ma, so, using this, it is easy to find the mass.
f = ma Divide by a for both sides
m = f/a Formula for mass!
The formula for mass is m = f/a, where f is force and a is acceleration.
Substitute.
m = (250 N)/(10 m/s^2)
m = 25 kg
As you inhale, your ribs move up and out decreasing the internal pressure and increasing the volume of the lungs forcing air into the lungs from an area of externally high pressure in comparison to the low internal pressure.
