We are asked to solve for the arc length of the intercepted arc and the formula is shown below:
Arc length = 2*pi*r(central angle/360°)
r = 5 feet
central angle = 10°
Solving for the arc length, we have:
Arc length = 2*3.14*5 (10/360)
Arc length = 0.872 feet
The arc length is 0.872 feet.

Answer:Hence, the name of the NaOH is Sodium hydroxide.
Explanation:
In strong base NaOH is made up of three element sodium , oxygen and hydrogen.
NaOH dissociates is into cation and anion in its aqueous solution:
While naming the ternary compound:
- First write the name of cation present, here the cation is of sodium that
. - followed by space then write name of the anion , here anion present in a polyatomic anion that
, the name of this polyatomic anion is hydroxide.
Hence, the name of the NaOH is Sodium hydroxide.
Its atomic radius increases because there is less electron shielding after the sodium loses one e-. Sodium is a nonmetal which means it forms an anion. Anions always increase from their original atomic radius
The answer is going to be C) because
A)If u add something then the whole project will be messed up
B)If you don't control the variable then you will keep messing up
d)When you know the measurements for the experiment you should make sure you have them correct when measured
Hopes This Helps:)
