2 atoms of P (phosphorus) and 5 atoms of O (oxygen)
Explanation:
The chemical formula of a generic compound is written as

where
A and B are the symbols of the elements contained in the compound
n and m are the number of atoms of each element, A and B respectively
In this problem, the compound given is

where:
- P is the symbol of the chemical element phosphorus
- O is the symbol of the chemical element oxygen
We see that the number following P is 2, so there are 2 atoms of phosphorus, while the number following O is 5, so there are 5 atoms of oxygen.

It's true charged particles are always acted on by an electric field.when the velocity of the electron is parallel to the magnetic field, the magnetic force vanishes.
50N.
The magnitude of the reaction to any force is equal to the magnitude of the first force. (See Newton #3.)
Mechanical advantage (MA = slope/height)
here length of slope = 9Hheight = H so mechanical advantage = ---- 9H/H= 9
