The model below shows a carbide ion. 8 light grey and 6 dark grey balls sit at the center with 2 concentric black rings around t

azamat

Answer:

This carbide ion change into a neutral carbon atom.

Explanation:

Given that,

Light grey balls = 8

dark grey balls = 6

medium grey balls = 2

Charge on dark grey ball = +1

Charge on light grey ball = 0

Charge on medium grey ball = -1

We need to change this carbide ion to a neutral carbon atom

Using given data

A dark grey ball has one positive charge. It means, it is a proton.

A light grey ball has has zero charge. It means, it is a neutron.

A medium grey ball has one negative charge.It means, it is a electron.

We know that,

The number of proton and number of electron is equal in a neutral atom.

So, No charge is present on the given model of atom.

Therefore, we can say that the atom is neutral.

We know that,

The sum of total number of protons presents in an atom it is called atomic number.

So, The total number of protons is 8, the total number of electrons is 8 and the total number of neutrons is 9 in given atom.

Hence, This carbide ion change into a neutral carbon atom.

A truck starts from rest with an acceleration of 0.3 m/ S^2 find its speed in km/h when it has moves through 150 m

Nadya [2.5K]

Answer:

9.5 m/s

Explanation:

Distance, S = 150m

Acceleration, a = 0.3 m/s^2

Initial velocity, u = 0 m/s

Final velocity, v

Use kinematics equation

v^2 - u^2 = 2aS

v^2 - 0 = 2*0.3*150 = 90

v = sqrt(90) = 9.49 m/s

How is a flywheel constructed to maximize its rotational inertia?

BigorU [14]

Answer:

It is constructed with a high mass and a high raidus.

Explanation:

The rotational inertia I for every object is calculated as:

cMR^2 = I

where c is a constant, M is the mass of the object and R the radius of the object.

So, for a flywheel, the rotational inertia is calculated as:

I = $\frac{1}{2}MR^2$

Then, for constructed a flywheel with the maximun rotational inertia we have to set the maximum mass and the maximun radius.

What two forces limit the height to which capillary action will take water up a tube?

Jobisdone [24]

Capillary action occurs when the adhesion to the walls is stronger than the cohesiveforces between the liquid molecules. The height to which capillary action will take water in a uniform circular tube (picture to left) is limited by surface tension and, of course, gravity.

Hope this helps. :)
