"did you press the switch?"
Yes carbon dioxide is needed for photosynthesis while cellular respiration needs oxygen and dispurses carbon dioxide
Answer:

Explanation:
The kinetic energy of a rigid body that travels at a speed v is given by the expression:

The equivalence between mass and energy established by the theory of relativity is given by:

This formula states that the equivalent energy
can be calculated as the mass
multiplied by the speed of light
squared.
Where
is approximately 
Hence:


Therefore, the ratio of the person's relativistic kinetic energy to the person's classical kinetic energy is:

Answer:
A. 340 meters/second
I think this is the right answer.
