The intersection angle of a 3 degree curve is 45.2 degrees. What is the length of the curve? of Select one: O a. 455 m O b.573 m
ValentinkaMS [17]

Explanation:

Relation between length of a curve and angle is as follows.

               l = R \times \Theta

where,   R = radius of curve

         \Theta = angle in radians

Also,     l = R \times \Theta \times \frac{\pi}{180}  .......... (1)

If curve has a degree of curvature D_{a} for standard length s, then

               R = \frac{s}{D_{a}} \times \frac{180}{\pi}   ........... (2)

Now, substitute the value of R from equation (2) into equation (1) as follows.

               l = \frac{s \times \Theta}{D_{a}}  

If s = 30 m, then calculate the value of l as follows.

                 l = \frac{s \times \Theta}{D_{a}}  

                   = 30 \times \frac{45.2}{3}              

                   = 452 m

thus, we can conclude that the length of the curve is 452 m.

What is the type of weak bond between the hydrogen of one molecule and the nitrogen of another molecule, where the two don't act
Aliun [14]
<h2>Hydrogen Bonding</h2>

Explanation:

  • Hydrogen bonding is a type of weak bond.
  • Hydrogen Bonding occurs when the hydrogen atom of one molecule is bonded with a molecule of high electronegativity element like nitrogen of another molecule.
  • It is a type of dipole-dipole interations.
  • The nitrogen is a highly electronegative element that forms a weak bond with the hydrogen atom of another molecule with dipole-dipole interaction.
  • Hydrogen bonds are weaker than covalent and ionic bonds.
  • Therefore the type of bond is Hydrogen bond.
