large solar panels are expensive
the energy it collects is 100% clean and renewable
doesn't create energy under certain weather conditions
Explanation:
The process by which atoms are arranged to form a material with a crystal shape is called crystallization.
With the help of crystallization process we can purify a solid compound.
For example, ice and snowflakes occur due to crystallization of water.
In this process, small quantity of desired solvent is added into the impure solid. Then it is heated to let the solid dissolve and after that it is cooled down so that crystals are formed. Then with the help of vacuum filtration pure solid is extracted.
Answer:
Crystallization is the correct answer.
Explanation:
B. Alfred Wegener
C. Charles Richter
D. Abraham Ortelius
Answer:
The answer should be 0.825
Explanation:
I took like 20 mins to figure this out lol
212*f....... as that kid tried to explain the combustion process, and failed... the process isn't exactly the same for all heat engines... therefore, there has to be a universal heat that of in which has a standard heat of 212 degrees fahrenheit
Answer:
Two tunnig fork of frequency 520 Hz and 524Hz are vibrated together. It means beats form due to it .
f₁ = 524 Hz
f₂ = 520 Hz
Beat period = 1/number of Bea are formed per unit time
= 1/(f₁ - f₂)
= 1/(524 - 520)
= 1/4 sec
Now, time inveral between successive maximum and minimum intensities = beat period= 1/4 sec
Explanation:
b. be 870 mm higher in the arm connected to the gas cylinder.
c. be 118 mm higher in the arm connected to the gas cylinder.
d. be 118 mm higher in the arm open to the atmosphere.
P = absolute pressure in gas container connected to open-end U-tube = 116 kPa = 116000 Pa
we know that, 1 atm = 101325 Pa and 1 atm = 760 mm of Hg , hence
P = 116000 Pa (1 atm/101325 Pa) (760 mm of Hg/1 atm)
P = (116000 x 760/101325) mm of Hg
P = 870.07 mm of Hg
P₀ = atmospheric pressure = 752 mm Hg
Level of mercury is given as
P' = P - P₀
inserting the values
P' = 870.07 - 752
P' = 118 mm
so correct choice is
d. be 118 mm higher in the arm open to the atmosphere.
The level of mercury in the tube would be 118 mm higher in the arm connected to the gas cylinder, as determined by converting kPa to mm Hg and calculating the pressure difference between the gas pressure and atmospheric pressure.
In order to solve this problem, we need to convert all units to the metric units system for consistency. First, let's convert the pressure of the atmosphere from mm Hg to kilopascals (kPa), knowing that one atmosphere which equals 760 mm Hg is approximately 101.3 kPa.
So, the atmospheric pressure is (752 mm Hg / 760 mm Hg) * 101.3 kPa ≈ 100.4 kPa.
The difference between the gas pressure and the atmospheric pressure gives the pressure of the mercury in the tube, since pressures are additive. So, the pressure difference is 116 kPa - 100.4 kPa = 15.6 kPa.
Finally, we convert this pressure in kPa back to mm Hg to get the height difference. By doing the inverse conversion, we get 15.6 kPa * (760 mm Hg / 101.3 kPa) ≈ 118 mm Hg. Therefore, the level of mercury in the tube will be 118 mm higher in the arm connected to the gas cylinder, corresponding to the option
c. be 118 mm higher in the arm connected to the gas cylinder.
