Answer:
Step-by-step explanation:
<h3>Given</h3>
- Θ= 168°
- t = 0.28 sec
- r = 3 mm
<h3>To find </h3>
<h3>Solution</h3>
<em>Formula for linear velocity</em>
<u>Converting the angle measure from degrees to radians</u>
- 168° = 168*π/180 = 168*3.14/180 = 2.93
<u>Substituting values</u>
- v = 2.93*3/0.28 mm/sec =
- 31.39 mm/sec =
- 0.03 m/sec rounded to nearest hundredths
4.36 for number 8 and 9 is 6.19
Answer:
Step-by-step explanation:
hen molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide. These two processes are represented by the two chemical equations shown at right.
SLOPE OF THE LINE:- (y2-y1)/(x2-x1)
here x1= 0 , y1 = 3 , x2 = -1 , y2= 4
Now Slope :- (4-3)/(-1-0)
Slope :- -1
