The speed of light is 299,792,458 meters per second in vacuum,
somewhat less in any material. How much less depends on the material.
Answer:
when all forces acting on an object remain the same
It appears to be a <span>spiral shape. </span>
The acceleration of the mass down the plane is determined as (4mg sinθ)/(3mr²).
<h3>Conservation of angular momentum</h3>
The acceleration of the mass down the plane is determined by applying the principle of conservation of angular momentum.
Fr = Iα
where;
- F is weight of the object parallel to the plane
- r is the radius of the flywheel
- I is moment of inertia
- α is angular acceleration
(mg sinθ)r = Iα
(mg sinθ)r = I(ar)
(mg sinθ) = I(a)
Thus, the acceleration of the mass down the plane is determined as (4mg sinθ)/(3mr²).

Answer:
vector with direction equal to the axis X.
Explanation:
We use the Gauss Law and the superposition law in order to solve this problem.
<u>Superposition Law:</u> the Total Electric field is the sum of the electric field of the first infinite sheet and the Electric field of the second infinite sheet:
<u>Thanks Gauss Law</u> we know that the electric field of a infinite sheet with density of charge σ is:
Then:
This electric field has a direction in the axis perpendicular to the sheets, that means it has the same direction as the axis X.
