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:
Low power
Explanation:
Low power would allow for the full image of the red blood cells and would appear as small circles.
Answer:
2-chloro-4-methylpentanal.
Explanation:
Hello there!
In this case, according to the chemical compound:
CH3-CH-CH2-CH-CHO
| |
CH3 Cl
We can see the main functional group is an starting carbonyl, which means this is an aldehyde. Moreover, we can see a Cl-substituent on the second carbon and a methyl substituent on the fourth carbon. Therefore, the IUPAC name turns out: 2-chloro-4-methylpentanal.
Best regards!
From Avogadro we obtained a physical constant of matter which is Avogadro's number, and from both scientists we understand that elementary gases such as hydrogen, nitrogen, and oxygen were composed of two atoms.
<h3>What is Avogadro's number?</h3>
Avogadro's number, or Avogadro's constant, is the number of particles found in one mole of a substance.
The Avogadro's number is given as 6.02 x 10²³.
Summary of Josef Loschmidt and Amedeo Avogadro Contribution to chemistry.
- Equal volumes of gas contain equal numbers of molecules,
- Elementary gases such as hydrogen, nitrogen, and oxygen were composed of two atoms.
Thus, from Avogadro we obtained a physical constant of matter which is Avogadro's number, and from both scientists we understand that elementary gases such as hydrogen, nitrogen, and oxygen were composed of two atoms.
