Determine the number of sig figs in the following numbers
I have counted and there are 25 people in a class. (Focus on the number 25 in this sentence.) How many sig figs are there?
Review the elevator question. You must be able to label why something is positive (applied force) and something is negative (Opposite direction of the applied force).
FNET= -960 N (The force is negative because it is in the opposite direction of the motion of the system. Think about this. The elevator is going up. The opposite of up is down. That is the same as 215 pounds!)
Explain what is wrong with the following sentence: A man walked at a velocity of 12 m/s.
There is no direction.
A girl participating in cross-country spends the afternoon practicing, and ends the practice completely tired from her hard work, despite the fact that her average velocity during the practice was 0.0 m/s. Explain how this situation is possible.
She ran back to where she started, so technically there was no displacement.
