There is a vector A with magnitude 5 units pointing toward west, and a vector B with magnitude 3 units pointing toward south. Using vector
addition, what is the magnitude of the resultant vector?

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
