Answer:
I think the answer is y-z>0
Explanation:
Relation between length of a curve and angle is as follows.
l = 
where, R = radius of curve
= angle in radians
Also, l =
.......... (1)
If curve has a degree of curvature
for standard length s, then
R =
........... (2)
Now, substitute the value of R from equation (2) into equation (1) as follows.
l =
If s = 30 m, then calculate the value of l as follows.
l =
=
= 452 m
thus, we can conclude that the length of the curve is 452 m.
Answer:
U-235 is an isotope of uranium
Explanation:
The most stable form of uranium isotopes is 235. (0.7198–0.7202%)
Answer:
a) The functional group that will be evident in the IR spectrum is the OH group.
b) OH group appears between 3200-3600 cm⁻¹
c) An important impurity that have the same functional group is water.
Explanation:
Eugenol is a chemical substance that consist in a benzene that have in 1 an alcohol, in position 2 a methyl ether and in position 4 an 1-propene bonded by the terminal alkyl carbon.
a) Having this in mind, the functional group that will be evident in the IR spectrum is the OH group.
b) This OH group appears between 3200-3600 cm⁻¹
c) An important impurity that have the same functional group is water. When you have water in your sample a big signal will appear in this zone and it is possible that overlapes the OH signal of eugenol.
I hope it helps!
