PLEASE ANSWER CORRECTLY! Suppose you are using a system of units based on the centimeter (cm) for length, the gram (g) for mass, and the second (s) for time.

The kinetic energy that an object has because of its motion is equal to half its mass times its speed squared, or KE = 1/2 mv2.

In this system of units, what units would be used to express KE?

A. g. cm/s
B. g. cm/s
C. kg. cm² /s^2
D. g. cm² /s^2​

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
