You need to think through what the problem is telling you. Remember, you have three heats: qcalorimeter qwater qmetal Each one of these q’s is determined by the equation q = (m) x (c) x (deltaT) When you are given the mass of the calorimeter, that’s the “m” in the equation for qcalorimeter. When you are give...
While we have designed each level of Apologia elementary math to share some aspect of a design theme with a title from the Apologia’s science Young Explorer Series, each math and science course can be completed separately. None of the courses are dependent on the other. For example, Level 1 mathematics has an astronomy...
Here is the pattern we try to follow on all of our solutions. If all of the math operations are the same, i.e. all multiplication/division or all addition/subtraction, then we will not round until the very end of the calculations. If the math operations switch, i.e. switches from multiplication to addition, then we wil...
Usually, the decision about whether or not to use scientific notation is up to you. An answer of 1.2×103 is equivalent in EVERY WAY to 1200. Thus, you can answer either way. But be sure to check to see if the question states how the answer needs to be given. There is one condition under which scientific notation MUST...
YES!! You should definitely use a calculator with our courses. Please see our Calculator Buying Guide attached below. There are several recommended, but please note that the calculator must be a SCIENTIFIC calculator. There are two important reasons for this: **Scientific calculators allow you to enter numbers in s...
Students can enroll in the [ Significant Figures and Precision ][1]Self-Paced Course taught by Live Classes teacher, Mr. Dan Martin. [1]: https://online.apologia.com/courses/significant-figures-precision-self-paced ...
You have to set the gravitational force equal to the centripetal force to understand the relationship between the two satellites. After all, the gravitational force IS the centripetal force: Fc = (msat)x(v)2/r Fg = Gx(mearth)x(msat)/r2 Gx(mearth)x(msat)/r2= (msat)x(v)2/r Gx(mearth)/r = v2 v = square root (Gx(meart...

You have to remember that the rules for addition and subtraction are totally different than the rules for multiplication and division (see pp. 25-26). In addition and subtraction, you DO NOT count significant figures. Yes, each of those numbers has two significant figures, but that is not relevant to addition and subtr...
In the first part of this example, you have (6.63 x 10-34 J/Hz) x (2.3 x 1016 Hz) You multiply the numbers: 6.63 x 2.3 = 15 then the exponents. Since you are multiplying, you add the exponents: (10-34) x (1016) = 10(-34 +16) = 10-18 Thus, the answer is 15 x 10-18, but that is not standard. To make it standard, yo...
