The radius of a circle is the distance from the center of a circle to any point of a circle.
The given sentence best describes: b. Newton's second law, the law of acceleration.
Newton's Second Law of Motion is also referred to as the law of acceleration and it states that the acceleration of an object or body is directly proportional to the force acting on the object or body and inversely proportional to its mass.
Mathematically, Newton's Second Law of Motion is given by the formula;
In this scenario, as a result of the mass possessed by the iron man on the left, it took more force to accelerate him than it took to accelerate the iron man on the right. Hence, the above best describes Newton's Second Law of Motion, which is also referred to as the law of acceleration.

Answer:
D = 2.828 m
Explanation:
given,
distance of source of light = 1.24 m below surface of pool
refractive index of the water = n₁ = 1.33
refractive index of air = n₂ = 1
refraction angle be = 90°
let C be the critical angle
Radius = d tan C
d is the depth of the source
Using Snell's law
n₁ sin C = n₂ sin R
1.33 x sin C = 1 x sin 90°
C = 48.75°
hence,
R = 1.24 x tan 48.75°
R = 1.414 m
Diameter = 2 x R
D = 2 x 1.414
D = 2.828 m
Answer:
C.subscript
Explanation:
The number 3 is a subscript on the hydrogen atom in ammonia NH₃.
Subscript is a lower notation on a reference atom. It states the number of hydrogen atom covalently bonding with the single N atom.
The superscript is located up. For example P², the 2 is a superscript.
The coefficient is the number before a compound or atom e.g 2C represents two atoms of Carbon.
The numerator is the upper value in a fraction. The denominator is the one beneath.
A option will be the answer.
