What is the total charge of a nucleus of a nitrogen atom?

2 answers:

8 0

<span>The charge of every atom is neutral. This is because the positively charged protons are cancelled out by the negatively charged electrons.</span>

<span>Every atom has the same number of electrons as there are protons, thus making every atom neutrally charged. Therefore, there is no charge in a nitrogen atom, or any atom to begin with. The only possibly charged things are ions.</span>

1) One piece of science equipment that you might not have been introduced to is the graduated cylinder. measure volume of a liquid.
2) Although you need to be careful when using a Bunsen burner, I think it is one of the most interesting lab tools to use. A Bunsen burner is a heat source used to raise the temperature.

That's

1 mmHg $\cong$ 0.0013 atm

So we have

If 1 mmHg $\cong$ 0.0013 atm

Then 732 mmHg will be

732 × 0.0013 atm

We have the final answer as

what is the change in the velocity of the biker below as he travels from point b to point c ? ..... What is his acceleration fro

Furkat [3]

The change in the velocity = 4 m/s

Acceleration = 4 m/s²

<h3>Further explanation</h3>

Given

vo = initial velocity = 4 m/s

vf = final velocity = 8 m/s

t = 1 s

Required

The change in the velocity

Acceleration

Solution

the change in velocity =

$\tt vf-vo=8-4=4~m/s$

Acceleration = ratio of a change in velocity and the time

$\tt a=\dfrac{\Delta v}{t}= \dfrac{vf-vo}{t}$

Input the value :

$\tt a=\dfrac{4~m/s}{1~s}=4~m/s^2$
