Providing 1 mile is 5280 feet, then,
It will travel,
in 15 seconds.
Answer:
4 meters per second
Step-by-step explanation:
120 divided by 30 = 4
Answer:
1. Group A and B agree with each other.
2. Group A and C do not agree with each other.
Step-by-step explanation:
When we are analizing this problem, we will see what are the ranges of this measured times. Since we are taking into account the error we can see that :
- Group A varies from 7.34-0.05 to 7.34+0.05. So the limits are (7.29 ;7.39)
- Group B varies from 7.38-0.03 to 7.38+0.03. So the limits are (7.35; 7.41)
- Group C varies from 7.46-0.06 to 7.46+0.06. So the limits are (7.40; 7.52)
Question 1 is about the overlapping response in Group A and Group B. And yes, we have an overlap between 7.35 to 7.39. Among this times both group A and B are in agree with each other within the experimental uncertainty.
Question 2 is now referring to Group A and Group C. And no, there isn't any common time where both groups agree with each other.
\left[x _{4}\right] = \left[ \frac{z}{2}+i \,\sqrt{\frac{1}{2}}\,\sqrt{\left( \frac{3\,z^{2}}{2}+\sqrt{2}\,\sqrt{z^{4}}\right) }\right][x4]=[2z+i√21√(23z2+√2√z4)] totally answer
3.33 since we know 12 is for 40 we can set up an equation
