Answer:
It is sometimes called the factor label approach because units are treated as a factor (along with a numeric factor) in a quantity like 25 g, allowing us to subject the unit to algebraic operations as if they were variables.
Explanation:
It is sometimes called the factor label approach because we can treat a quantity like 25g as a product of a numerical factor and a unit factor, allowing us to subject the unit to arithmetic operations as if they were variables. Dimensional analysis can be most helpful when helping to set up a problem involving multiplication or division, but it is not limited to multiplication and division: Adding or subtracting quantities, for example, requires they have the same unit, just like adding algebraic terms 5x and 6x, and this rule can be used to help set up or check a calculation.
Answer: A minimum of $242.60 and a maximum of $1,100 per month.
Explanation:
Answer:
A machine consumes energy whereas an engine produces energy. Engine converts heat energy to Mechanical Energy but machine converts all forms of energy to mechanical energy except heat energy. A engine runs a machine,without a engine a machine can't run.
Explanation:
Incomplete question. The remaining part of the question read;
How did the potential energy of the two vehicles change? Did the potential energy of one vehicle change more than the other? Why do you think so?
<u>Explanation:</u>
1. The potential energy of the two vehicles increased because we could observe that they have unlike poles moving towards the center of the magnet. So the magnet field would be repealing both toy vehicles.
2. The <u>potential energy of </u><u>the pink vehicle</u><u> change more than </u><u>the purple vehicle.</u> This is evident as we notice the pink vehicle is closer to the center of the magnet than the other.
3. The reason for this is because Lucia exerts more force (potential energy) on the pink vehicle to fight the repelling effect of the magnet
