7.4= not 740,000 mg because 7400,000 mg are in 7.4 kilograms. not 740 grams because there is 7,400 grams in 7.4 kilograms. not 74,000 cg because there is .74 cg in 7.4 kilograms. so the answer is 7.4kg=74hg Hope it helps!

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 ο΄10-19 c ο΄1 v = 1.6 ο΄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
Isuck at math ; ^; m a student solved this problem and said the answer is 3 feet. chase had a roll of ribbon that contained 7 7/8β feet of ribbon. he cut off one piece that was 3 5/8β feet long and another piece that was 1 1/4β feet from the roll. how much ribbon was left on the roll? is the student's answer reasonable? yes, the answer is reasonable. no, the answer is not reasonable. it should be about 2 feet. no, the answer is not reasonable. it should be about 13 feet. no, the answer is not reasonable. it should be about 4 feet.
Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x β 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, β8) included in the solution area for the system? justify your answer mathematically. (4 points)
