Explanation:

I don't know what values you have measured, or what <em>Ladybug Revolution</em> is, but I can show you the equations for rotational motion.

Angular displacement is:

Δθ = ω₀ t + ½ αt²

where ω₀ is the initial angular velocity, α is the angular acceleration, and t is time.

Assuming the radius is constant, the arc length is radius times angular displacement.

s = rΔθ

Using the equation for angular displacement, we can see that if two points have the same angular velocity and same angular acceleration, then they also have the same angular displacement.

What is the critical angle for the interface between water and light flint? nflint= 1.58, nwater=1.33?

Angelina_Jolie [31]

When light crosses the interface between a medium with higher refractive index and a medium with lower refractive index, there is a maximum value of the angle of incidence after which there is no refraction, but all the light is reflected, and this maximum value is called critical angle.

The critical angle is given by
$\theta_C = \arcsin ( \frac{n_2}{n_1} )$
where n1 is the refractive index of the first medium while n2 is the refractive index of the second medium. In our problem, n1=1.33 and n2=1.58, so the critical angle is
$\theta_C = \arcsin ( \frac{1.33}{1.58} )=57.3 ^{\circ}$

What is the law of inertia for rotating systems in terms of angular momentum?

saw5 [17]

Answer:

Explanation:

The law of inertia states that if an object is in motion will remain in motion unless an external force is applied to it.

law of inertia for the rotating system in terms of angular momentum states that the angular momentum of a system will remain the same unless an external torque is applied to the system.

External Torque either increases or decreases the angular velocity thus changing angular momentum.

IN THIS FORMULA FOR WATER WHAT DOES THE SUBSCRIPT 2 INDICATE

masha68 [24]

The chemical formular for water is H2O.
The H aspect of the formula stands for hydrogen gas and the subscript 2 which is attached to the H symbol signifies that two atoms of hydrogen are joined together, that is two atom of hydrogen are present.
The chemical formula of water indicates that, two atom of hydrogen react with one atom of oxygen to form one molecule of water.
In chemical formulae, subscripts are normally used to indicate the number of atoms that are present in a molecule.
