Coal plants use a boiler to produce steam.
Answer:
0.16Hz
Explanation:
wavelength (λ) = 125 meters
speed (V) = 20 m/s
frequency (F) = ?
Recall that frequency is the number of cycles the wave complete in one
second. And its value depends on the wavelength and speed of the wave.
So, apply the formula V = F λ
Make F the subject formula
F = V / λ
F = 20 m/s / 125 meters
F = 0.16 Hz
Answer:
Explanation:
Given data:
vapor pressure P_1 = 0.6 L
Volume = 2L
Temperature remain constant
No change in vapor pressure. This is because vapor pressure is calculated from the temperature of the liquid and not the volume of the container. Since the temperature is constant therefore vapor pressure remian constant..
