Which of the three subatomic particles is responsible for determining the reactivity of an element?

The three subatomic particles are the electron, proton and neutron

Explanation:

There are three subatomic particles in an element which are responsible to determine their reactivity are called as electrons, protons and neutrons. These three particles have different charges associated with them like electron are negatively charged,  protons are positively charged and neutrons are neutrally charged  (i.e) no net electric charge is associated with them. The nucleus is the center of the atom.

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff

explanation:

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
