Physics
1 answer:
prisoha [69]3 years ago
8 0

Answer:

A positive ion is formed by the removal of electron(s) from an atom or group of atoms.

A negative ion is formed by the addition of electron(s) to an atom or group of atoms.

Explanation:

A positive ion, also known as cation is formed by the removal of electron(s) from an atom or group of atoms until there are fewer electrons than protons. It positive ion because it contains more proton than electron.

A negative ion, also known as anion is formed when an atom or group of atoms gains electron(s) until there are more electrons than protons. It negative ion because it contains more electron than proton.

sashaice [31]

Answer:

22.36 rad

Explanation:

Applying,

ω = θ/t.............. Equation 1

Where ω  = angular velocity, θ = angular displacement of the baseball, t = time

make θ the subject of the equation

θ = ωt............... Equation 2

From the question,

Given: ω = 350 rev/min = 350(0.10472) = 36.652 rad/s, t = 0.61 s

Substitute these values into equation 1

θ = 0.61(36.652)

θ = 22.36 rad

Hence the angular displacement of the baseball is  22.36 rad
