a reaction occurs in which carbon combines with sulfur to form carbon disulfide is this a chemical reaction or a nuclear reactio

romanna [79]

Answer:

a chemical reaction where electrons mix.

Explanation:

A nuclear reaction is when atomic nuclei combine, forming a new chemical element

A chemical reaction occurs when electrons from the last layer of atoms mix, forming molecules that have the same chemical elements as the reactants.

According to these definitions

C + 2 S → CS2

in a chemical reaction where electrons mix.

Where would you except to find the center of gravity of a plastic ruler

VARVARA [1.3K]

You would expect to find the center of gravity in a ruler in the middle because if you were to cut a ruler in half, depending on the center of gravity, you would have two equal pieces, which mean there is equal weight, meaning the middle is the center of gravity

Answer:

The new period is approximately 3.93 × 10⁻⁷ h

Explanation:

The radius of the planet = 5 × 10⁶ m

The acceleration due to gravity on the planet, a = 10 m/s²

The period of the planet = 25 h

The centripetal force, $F_c$ , is given by the following equation;

$F_c = \dfrac{m \cdot v^2}{r}$

Where;

v = The linear speed

r = The radius

Therefore, for the apparent weight, W, of an object to be zero, we have;

The weight of the object = The centripetal force of the object

W = Mass, m × Acceleration due to gravity, a

∴ W = $F_c$

Which gives;

$m \times a = \dfrac{m \cdot v^2}{r}$

$a = \dfrac{v^2}{r}$

∵ r = The radius of the planet

We have;

$10 = \dfrac{v^2}{5 \times 10^6}$

v² = 10 × 5 × 10⁶

v = √(10 × 5 × 10⁶) ≈ 7071.07 m/s

The new frequency = Radius of the planet/(Linear speed component of rotation)

∴ The new frequency = 5 × 10⁶/(7071.07) = 707.107 revolutions per second

The new frequency = 707.107 × 60 × 60 = 2545585.2 revolutions per second

The new period = 1/Frequency ≈ 3.93 × 10⁻⁷ hour.
