Which air mass provides the moisture that produces the clouds and precipitation?
Andreas93 [3]
The MT is the air mass that provides the moisture that produces the clouds and precipitation. An air mass is a volume of air that is defined by its temperature and water vapor or moisture content .  MT is the abbreviation of marine time air mass. Air masses can control the weather for a relatively long time period from a period of days, to months, Most weather occurs along the periphery of these air masses at boundaries called fronts.

Assuming that the smallest measurable wavelength in an experiment is 0.950 fm , what is the maximum mass of an object traveling
Arada [10]

Answer:

The maximum mass is 2.89x10^{-21}Kg

Explanation:

The wavelength of the electron can be determined by means of the De Broglie equation.

\lambda = \frac{h}{p} (1)

Where h is the Planck's constant and p is the momentum.

\lambda = \frac{h}{mv}  

m = \frac{h}{\lambda v}  (2)

Where m is the mass and v is the velocity.

Before using equation 2 it is necessary to express the wavelength from femtometers to meters.

\lambda = 0.950fm .\frac{1m}{1x10^{15}fm} -- 9.5x10^{-16}m

Finally, equation 2 can be used.

m = \frac{6.624x10^{-34} J.s}{(9.5x10^{-16}m)(241m/s)}

But 1J = Kg.m^{2}/s^{2}

m = \frac{6.624x10^{-34} Kg.m^{2}/s^{2}.s}{(9.5x10^{-16}m)(241m/s)}

m = 2.89x10^{-21}Kg    

Hence, the maximum mass is 2.89x10^{-21}Kg
