Answer:
George
Explanation:
George is correct because no matter the mass all objects will hit the ground at once because each has a certain amount of gravity needing them to pull it down for example your weight the bigger the person the heavier.
Answer:
Total magnification is the amount of magnification that can be achieved when all the optics involved in the magnification by the apparatus being used is taken into account.
Explanation:
Total magnification is the amount of magnification that can be achieved when all the optics involved in the magnification by the apparatus being used is taken into account. For example when an object is viewed under a microscope with just ocular and objective lenses, the object is magnified to it maximum magnification using both the ocular lens and objective lens and the total magnification can be calculated by multiplying the power of the objective lens and the power of the eye piece.
Total magnification = power of objective lens x power of eyepiece
If the machine works at a 70% efficiency it must complete 14,000 work out of the 20,000

Answer:
Vector Quantities Increase/Decrease in Temperature - The measurement of the medium's temperature is a scalar quantity; the measurement of the increase or decrease in the medium's temperature is a vector quantity. Velocity - The measurement of the rate at which an object changes position is a vector quantity.
