What is the net force when forces applied are 300 N to the right and 100 N to the right
labwork [276]

Answer:

400 Newtons to the right.

Explanation:

You have 300 Newtons that are being applied to the right and you also 100 Newtons to the right. When calculating net force with the forces that go the same direction, you add them. 300 plus 100 is 400. Therefore, it is 400 Newtons or N to the right. Hope this helps!

If you add 1 proton to Carbon, it will no longer be Carbon, it will be ________________.
Whitepunk [10]

Nitrogen

Explanation:

Adding one proton to a carbon atom makes Nitrogen.

A quick introspection on atoms:

  • An atom is made up of three fundamental particles.
  • They are protons, neutrons and electrons.
  • The protons are positively charged and the neutrons do not carry any charges.
  • Electrons are negatively charged.

The difference between an atom and another is the number of protons in them. This is the atomic number.

The periodic table of element is a list of elements arranged based on the number of protons they have. Every element on the table has unique number of protons which makes it differ from another.

  • Atoms do not readily lose their protons because they are held by nuclear forces in the nucleus of an atom.

When an element gains a proton, it becomes another element.

    Carbon has proton number of 6

 If a proton is added to it, it becomes 7

This is the proton or atomic number of nitrogen.
