How do protons, neutrons, and electrons determine the properties of an atom?
( explain for someone who doesn't understand this stuff)

Number of protons = Number of electrons

Protons = positively charged atoms

Electrons = negatively charged atom

Neutrons = no charge atoms

The number of protons = electrons because the charge can cancel themselves out

Number of electrons = Determines boiling/ melting point

Lots of electrons = High boiling/ melting point

Low number of electrons = low boiling/ melting point

Explanation:

i don't understand. explain it clearly

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
