EVERYTHING electrical that we do in the real world ... positive and negative electric charges, static electricity, positive and negative electric current, lightning traveling up or down ... is ALL done with particles of NEGATIVE charge, called electrons.

== When you pile on extra electrons, you have a negative static charge.

== When you strip electrons away, you leave a positive static charge.

== When you make electrons flow through something, you have electric current. If it flows one way, it's called positive current. If it flows the other way, it's called negative current. But it's always electrons (negative charges) that are flowing from place to place.

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 25 N force is used to push a box across a floor against a frictional force of 14 N. The box

Svetlanka [38]

Answer:

$m = 44~Kg$

Explanation:

<u>Net Force</u>

Newton's second law explains the dynamics principles when a number of forces are applied to an object.

The net force vector is the sum of the individual vector forces applied. The magnitude of the net force is related to the magnitude of the acceleration of the body as follows:

$Fn=m.a$

Furthermore, the acceleration can be calculated if we know the kinematic behavior of the body:

$\displaystyle a=\frac{v_f-v_o}{t}$

Where vf, vo, and t are the final speed, initial speed, and time, respectively.

The box is pushed across the floor with a force of 25 N against a frictional force of 14 N.

The net force applied to the box is:

$Fn = 25 N - 14 N = 11 N$

We also know the box is accelerated from rest (vo=0) to vf=4 m/s in t=16 seconds, thus:

$\displaystyle a=\frac{4-0}{16}$

$a = 0.25~m/s^2$

From the equation:

$Fn=m.a$

We solve for m:

$\displaystyle m=\frac{Fn}{a}=\frac{11~N}{0.25~m/s^2}$

$\mathbf{m = 44~Kg}$

1 1.1.2 Quiz: The Nature of Physics

Natasha2012 [34]

Answer: Theory (D.)

Explanation:

A theory is based on years of careful scientific study, observation, and experimentation.

On the other hand, a law describes a phenomena without explaining it. An observation is merely a documentation of a phenomena and may or may not be explained. An experiment is a procedure done to test the effect of a specific variable, but does not necessarily explain WHY something occurs.

A horizontal vinyl record of mass 0.10 kg and radius 0.10 m rotates freely about a vertical axis through its center with an angu

Tresset [83]

Answer:

The angular speed of the record is 3.36 rad/s.

Explanation:

Given that,

Mass of record= 0.10 kg

Radius = 0.10 m

Angular speed = 4.7 rad/s

Moment of inertia $I=5.0\times10^{-4}\ kgm^2$
