Let , radius of sphere 1 is r .
So , radius of sphere 2 is 6r .
Surface area of sphere is given by :

So ,

Volume is given by :

Ratio of sphere 2 by sphere 1 is given by :

Therefore , the ratio of area and volume is 36 and 216 respectively .
Hence , this is the required solution .
I believe the answer is: B (oxygen and carbon dioxide)
I am not for sure, but good luck!
It would be the 2nd one because the higher the farther away from the equator. <span />
Answer:
The speed of cart B is 11.21 m/s.
Explanation:
Given that,
Speed of cart A = 9.25 m/s
Speed of cart B = 7.15 m/s
Mass of cart A = 72.0 kg
Mass of cart B = 55.0 kg
Speed of card A after collision = 6.15 m/s
We need to calculate the speed of cart B
Using conservation of momentum

Put the value into the formula



Hence, The speed of cart B is 11.21 m/s.
Answer:
The energy carried by an electromagnetic wave is proportional to the frequency of the wave. The wavelength and frequency of the wave are connected via the speed of light: Electromagnetic waves are split into different categories based on their frequency (or, equivalently, on their wavelength).
