Answer:

velocity of combined objects is 6 m/s

Explanation:

As per law of conservation of momentum

total momentum before collision = total momentum after collision

since the two objects sticks together after collision so we will have

$m_1v_{1i} + m_2v_{2i} = (m_1 + m_2) v$

Now plug in all values in it

$300(10) + 100(-6) = (300 + 100) v$

$3000 - 600 = 400(v)$

$2400 = 400 v$

$v = 6 m/s$

so the missing value in the table is velocity which is 6 m/s

An example of an atom that has no change is one that has A. 1 proton, 2 electrons, and 3 neutrons B. 3 protons,2 electrons, and

Vikki [24]

Your question asks which is an example of an atom that has no change, or charge.

Your answer would be C). 2 protons, 2 electrons, and 1 neutron

These atoms would be known as a neutral atom.

In order for an atom to be neutral, it must have the same amount of protons and electrons.

We know that Protons are positive

We also know that Electrons are negative

In order for the atom to be neutral, they must have an equal amount of protons and neutrons to "cancel out"

In answer choice C, you would see that there are 2 protons and 2 electrons.

2- 0 = 0, in which allows this atom to be neutral.

Therefore, answer choice C. 2 protons, 2 electrons, and 1 neutron would be your answer.

Which part of the electromagnetic spectrum is divided into seven ranges of wavelengths and is the part visible to the human eye

oksano4ka [1.4K]

In one of the most amazing coincidences in all of science,
the part of the electromagnetic spectrum that's visible to the
human eye is called "visible light".

Visible light is not 'divided' into anything. We mention the names
to seven of the colors in visible light. But all of the thousands of
OTHER colors that we can see are in there too, even though we
don't bother to list their names when we buzz through the rainbow
in the third grade.
