The atomic number, or number, is the described as the number of in the nucleus of an chemical element. a) proton, protons b) photon, photons c) neutron, neutrons d) electron, electrons

Option (A) is the correct answer.

Explanation:

Atomic number is defined as the sum of total number of protons present in an atom. Each element has different atomic number.

And, atomic mass is the summation of total number of protons and electrons present in the nucleus of an atom.

For example, atomic number of fluorine is 9 which also means that a fluorine atom contains 9 protons.

Thus, we can conclude that the atomic number, or proton number, is the described as the number of protons in the nucleus of a chemical element.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
