Here is the comparison of the properties of electrons, neutrons and protons:
<span>Electrons are negatively-charged particles and are found outside the nucleus of the atom, They interact with other electrons of other atoms that result to different properties of atoms. They also determine the charge of the atom, or more preferably, the ion. For a neutral atom, they have the same number as that of the protons. Protons are positively-charged particles and are found inside the nucleus along with the neutrons. Protons and neutrons are collectively called nucleons. Protons determine the atomic number of the atom. Neutrons, on the other hand, are neutrally-charged particles and are found inside the nucleus. Along with the proton, they constitute the mass of the whole atom. Atoms of the same element but with a different number of neutrons are called isotopes.</span>

A uniform rod is 2.0 m long. The rod is pivoted about a horizontal, frictionless pin through one end. The moment of inertia of t
emmasim [6.3K]

Answer:

Angular acceleration = 6.37rad/sec²

Approximately, Angular acceleration =

6.4 rad/sec²

Explanation:

Length of the rod = 2.0m long

Inclination of the rod (horizontal) = 30°

Mass of the rod is not given so we would refer to it as = M

Rotational Inertia of the Rod(I) = 1/3ML²

Angular Acceleration = ?

There is an equation that shows us the relationship between Torque and Angular acceleration.

The equation is :

Torque(T) = Inertia × Angular Acceleration

Angular acceleration = Torque ÷ Inertia

Where:

Torque = L/2(MgCosθ)

Where M = Mass

L = Length = 2.0m

θ = Inclination of the rod (horizontal) = 30°

g = Acceleration due to gravity = 9.81m/s²

Inertia = 1/3ML²

Angular Acceleration =  (Mass × g × Cos (30°) × (L÷2)) ÷ 1/3ML²

Angular Acceleration =

(3 × g × cos 30°) ÷ 2× L

Angular Acceleration = (3 × 9.81m/s² × cos 30°) ÷ 2× L

Angular Acceleration = 3 × 9.81m/s² × cos 30°) ÷ 2× 2.0m

Angular Acceleration = 6.37rad/sec²

Approximately Angular Acceleration =

6.4rad/sec²
