Use the EE or EXP key on that calculator. You will have one or the other, but not both. This key has been designed to enter numbers in scientific notation. If you are using the 10x key, then you should stop because that key was not designed for scientific notation. **To enter 3.0 x 108, all you have to type in is ** ...
Using Time and Displacement to Calculate the Velocity of a Ball Rolling Down a 41.8 cm Board Sami S. Wright **Introduction** Calculating an object’s average velocity is important because it is applicable to real-life situations, such as how fast a car is going over a period of time. In this experiment, the amount o...
You did not square the radius term on the bottom of the equation. The gravitational force depends on the inverse of the radius SQUARED. When you square the radius and then divide, you get 4.5×108. ...

The printing number will be listed one of two ways: “1st printing, February 2004” or “10 9 8 7 6 5 4 3 2 1.” If your textbo...
The editors of the dictionary do not understand physics! There is no such thing as centrifugal force. For a force to occur, an equal and opposite force must exist as well (Newton’s Third Law). There is no equal and opposite force for “centrifugal force,” since it does not exist. ...
A figure within a number is significant if it is there to indicate precision. If, instead, it is there just to indicate the size of the number, it is not significant. Thus, a zero to the right of the decimal at the end must always be significant, because that zero does nothing to indicate the size of the number. The nu...
You must be forgetting to SQUARE the speed or you are making some other mistake, because the book is correct. If you take 6.67×10-11 and multiply by 5.98×1024, you get 3.98866…x1014. Then, if you take that number and divide by 6.6×103 squared, you get 9.156703…x106, which rounds to 9.2×106. ...
Significant figures rules are only used for measurements, not constants. You should not have to worry about the number of digits for constants and neither should that affect your significant digit calculations. The rules listed on pages 21-25 of the Chemistry textbook state that they are for measurements only. ...
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...
**Set up the equation:** (1.00) x sin(34.5) = (1.5) x sin (Theta2) **Then, you rearrange the equation by dividing both sides by 1.5:** (1.00) x sin(34.5)/1.5 = sin (Theta2) **Now, you evaluate everything on the left.** As long as your calculator is in degrees mode, when you use it to calculate the sin of 34.5, y...
