This is not really a physics question but I can still help. It’s easier if you make a table. I hope this helped.
Complete question is;
Marie observed people at a store. Which is a qualitative observation she may have made?
A. Twenty people walked into the store.
B. The store sells clothes.
C. It was 1:00 P.M.
D. all of the above
Answer:
Option B:The store sells clothes.
Explanation:
We want to find the one that is a qualitative observation;
Looking at the options;
A. Twenty people walked into the store. This denotes a quantitative measure because of the number 20.
B. The store sells clothes. This denotes a qualitative measure because it describes what she sells.
C. This is a quantitative measure because it deals with time of 1 pm which is quantitative.
Therefore, the correct answer is Option B
Answer:
The frequency of the wheel is the number of revolutions per second:
f= \frac{N_{rev}}{t}= \frac{10}{1 s}=10 Hz
And now we can calculate the angular speed, which is given by:
\omega = 2 \pi f=2 \pi (10 Hz)=62.8 rad/s in the clockwise direction.
Explanation:
Answer:
A) 29.4 m 17.0 m; B) 2 m
Explanation:
If a vector is 34.0 m in length and is directed 60.0° east of north (which means 30.0° over the horizontal), then its coordinates will be:
Horizontal: (34.0 m)cos(30.0°)=29.4 m
Vertical: (34.0 m)sin(30.0°)=17 m
If one person walks 8.0 meters in a straight line and then walks 5.0 meters in another straight line, then the minimum displacement would be to go back over his tracks, displacing himself 8m-5m=3m, while the maximum displacement would be going straight ahead, displacing himself 8m+5m=13m. Any answer outside this interval is impossible (2m).
