A carbon dioxide molecule in gravity free space may be viewed as three roughly equal masses with carbon in the middle and two oxygens in equilibrium on either side. Ignore the possible bending of the system in a transverse direction perpendicular to the line of the molecule. A) Assume vibrations along the line of the molecule and find the three normal modes (normal coordinates) and normal frequencies, assuming spring constants k and masses m.
B) Look up the values for the wavelengths of these frequencies and evaluate the spring constant (approximately) for your problem.

The answer is a.  i hope this

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.

What are your choices. i believe it might be mitochondria but i will know for sure when i see the choices. let me know okay i'm happy to answer
