Explanation:
I don't really know how to explain it, but this helped hopefully! :) Have a bless day
Answer: false
Explanation: the longer the period, the less thef= frequency
The water cycle is all about storing water and moving water on, in, and above the Earth. Although the atmosphere may not be a great storehouse of water, it is the superhighway used to move water around the globe. Evaporation and transpiration change liquid water into vapor, which ascends into the atmosphere due to rising air currents. Cooler temperatures aloft allow the vapor to condense into clouds and strong winds move the clouds around the world until the water falls as precipitation to replenish the earthbound parts of the water cycle. About 90 percent of water in the atmosphere is produced by evaporation from water bodies, while the other 10 percent comes from transpiration from plants.
There is always water in the atmosphere. Clouds are, of course, the most visible manifestation of atmospheric water, but even clear air contains water—water in particles that are too small to be seen. One estimate of the volume of water in the atmosphere at any one time is about 3,100 cubic miles (mi3) or 12,900 cubic kilometers (km3). That may sound like a lot, but it is only about 0.001 percent of the total Earth's water volume of about 332,500,000 mi3 (1,385,000,000 km3), If all of the water in the atmosphere rained down at once, it would only cover the globe to a depth of 2.5 centimeters, about 1 inch.
Answer:
Q = 2.95*10^5 kJ
Explanation:
In order to calculate the energy required to melt the cooper, you first calculate the energy required to reach the boiling temperature. You use the following formula:
(1)
m: mass of cooper = 540 kg
c: specific heat of cooper = 390 J/kg°C
Tb: boiling temperature of cooper = 1080°C
T1: initial temperature of cooper = 20°C
You replace the values of the parameters in the equation (1):
![Q_1=(540kg)(390\frac{J}{kg.\°C})(1080\°C-20\°C)=2.23*10^8J](https://tex.z-dn.net/?f=Q_1%3D%28540kg%29%28390%5Cfrac%7BJ%7D%7Bkg.%5C%C2%B0C%7D%29%281080%5C%C2%B0C-20%5C%C2%B0C%29%3D2.23%2A10%5E8J)
Next, you calculate the energy required to melt the cooper by using the following formula:
(2)
Lf: melting constant of cooper = 134000J/kg
![Q_2=(540kg)(134000\frac{J}{kg})=7.24*10^7J](https://tex.z-dn.net/?f=Q_2%3D%28540kg%29%28134000%5Cfrac%7BJ%7D%7Bkg%7D%29%3D7.24%2A10%5E7J)
Finally, the total amount of energy required to melt the cooper from a temperature of 20°C is the sum of Q1 and Q2:
![Q=Q_1+Q_2=2.23*10^8J+7.24*10^7J=2.95*10^8J=2.95*10^5kJ](https://tex.z-dn.net/?f=Q%3DQ_1%2BQ_2%3D2.23%2A10%5E8J%2B7.24%2A10%5E7J%3D2.95%2A10%5E8J%3D2.95%2A10%5E5kJ)
The total energy required is 2.95*10^5 kJ
When two or more waves combine to produce a new wave, that's 'interference'.
-- If the new wave has larger displacements (amplitude), then it's <em>CON</em>structive interference.
-- If the new wave has smaller displacements (amplitude), then it's DEstructive interference.
