Wavelength =(speed)/(frequency)
Wavelength =(20 m/s) / (20/s)
Wavelength = 1 meter
Answer:
because gas molecules have more kinetic energy and are smaller than liquid molecules. diffusion in liquids is slower because the particles in a liquid move more slowly. it happens faster if the temperature is increased

Answer: A loss of oxygen
Explanation: There wasn’t enough reliable oxygen for the researchers to inhale
Answer:
Solon,
total mass (kg)= 100kg
height (h)= 25m
acceleration due to gravity = 9.8m/s²
so,
work done =m*g*h
= 100*9.8*25
= 24,500 joule
