Need answer now..need correct answer will mark brainliest..each year, the department of water works measures the chloride concentration level in the water. the first year, they found the chloride concentration changed by −1 3/5 mg/l . it is estimated that the chloride concentration will change −2 1/15 mg/l the next year. what is the total change that will likely occur in 2 years? enter your answer as a simplified mixed number in the box. mg/l

-1 3/5 + -2 1/ 15

get a common denominator or 15

 - 1 9/15 + -2 1 /15

-3 10/15

-3 2/3 mg/L

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
