Which of these is not true about the proton

a. protons exist within the nuclei of atoms

b. electrons surrounding atoms get pulled into the nucleus by protons

Option (B).

Explanation:

Atoms consist three subatomic particles that are electron, proton and neutron. Electrons participates in the formation of ions and has the ability to gain or lose the electrons.

Electron revolves around the nucleus whereas protons and neutrons are present inside the nucleus. Protons are positively charged and their number can not be changed inside the atom. Protons does not have the ability to push the electrons. Electron revolve in the fixed orbit and cannot fall down in the nucleus.

Thus, the correct answer is option (B).

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
