Answer:
The centripetal acceleration acting on the ball is 10.24 m/s²
Explanation:
Given;
mass of the ball, m = 3 kg
radius of the swing arm, r = 1 m
speed of the ball, v = 3.2 m/s
centripetal acceleration is given by;
a = v² / r
a = (3.2)² / 1
a = 10.24 m/s²
Therefore, the centripetal acceleration acting on the ball is 10.24 m/s²

Answer:
a. Chemical formula
Explanation:
A notation that shows which elements, and how many of each type a compound contains is a chemical formula.
Basically, a chemical formula helps scientists to show or illustrate the type and number of atoms present in a particular molecule or compound by using numerical subscript, ions and atomic symbol of a chemical element.
This ultimately implies that, a chemical formula is used to describe or denote the exact amount of atoms that make up a molecule or compound.
<em>Some examples of a chemical formula are;</em>
Water =
Sodium Hydroxide =
Hydrochloric acid =
Carbon II oxide =
B because it conducts electricity which means it contains a metal hope this helps
