In a uniform circular motion map, what is always true? check all that apply.

a. the dots are different distances apart.
b. acceleration vectors point in the direction of motion.
c. velocity vectors are always perpendicular to the circle.
d. acceleration vectors point toward the center of the circle.
e. velocity vectors are the same length.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
