From the law of atmosphere
Where
= constant and is number density where the height y = 0cm
= Number density at height y=3cm
Kb = Boltzmann constant
Re-arranging the equation to have the value of the gravity,
Since it is 30% of value above surface, therefore
Therefore the correct answer is C.
<h2>Answer:</h2>
The sun emits radiation in wavelengths of 10nm to 1mm.
<h3>Explanation:</h3>
The sun emits radiations of different types in electromagnetic spectrum.
99% of radiations are :
- Visible light: 400nm to 700nm
- Ultraviolet rays: 10nm to 400nm
- Infrared rays: 700nm to 1mm
C is the answer to this question. Hope this helps.!
1 watt means 1 joule of energy per second
The food processor uses 1,150 joules of energy per second.
The blade uses 950 joules per second to slice, dice, and puree.
The rest of the energy goes to heat the appliance's motor, or
overcome friction in the blade's bearings, etc. How much energy
does NOT go into slicing and pureeing ?
(1,150 watts) - (950 watts) = 200 joules per second
1 minute = 60 seconds
2 minutes = 120 seconds
Energy wasted in 2 minutes =
(200 joules/second) x (120 seconds) = <em>24,000 joules</em>
That's enough energy to operate a 34-watt CFL (curly) light bulb
for 11 minutes 46 seconds.
