Which two particles in an atom are equal in number

Answers

If you mean in mass, then the mass of one proton is approximately equal to the mass on one neutron. If you mean how many of each, then the number of protons is equal to the number of electrons. If the number of electrons was different from the number of protons, then you'd have an ion. An ion with a positive charge is a cation, and an ion with a negative charge is an anion.

Protons and electrons are the two equally abundant particles in an atom.

The atom's nucleus contains protons, which are subatomic particles with a positive charge. A +1 positive electric charge permeates each proton.

An atom's nucleus is surrounded by electrons, which are subatomic particles with a negative charge. An electric charge of -1 is carried by each electron.

The number of protons in the nucleus of a neutral atom is equal to the number of electrons encircling the nucleus. The atom becomes electrically neutral when the balance of positive and negative charges results in a net electric charge of zero.

An atom with the atomic number 6 for carbon, for instance, contains six protons and six electrons. Similar to this, an atom of sodium, which has an atomic number of 11, contains 11 protons and 11 electrons.

An atom is stable and maintains its distinctive chemical properties because it has an equal number of protons and electrons.

An optical fiber can make a light beam travel in a path that is curved or twisted? True or False

Answers

Answer:

True

Explanation:

An optical fiber is like a glass tube with very small radius. The light travels through these fiber following Total Internal Reflection principle. The movement of the light is not affected by the external factor or the shape of the fiber as long as it is intact. Even if it is twisted or curved, the light will travel as long as the fiber is not damaged physically.

hello their

If a car can go from 0 to 60 mi/hr in 8.0 seconds, what would be its final speed after 5.0 seconds if its starting speed were 50 mi/hr?

Answers

$a= (V)/(t) \ \ \ \Rightarrow\ \ a= (60\ [mi/hr])/(8\ [s]) \n \nthe\ final\ speed\ after\ 5.0\ seconds\n \nV=50\ [mi/hr]+5\ [s]\ \cdot (60\ [mi/hr])/(8\ [s])=50\ [mi/hr] + (5)/(8) \cdot 60\ [mi/hr]=\n \n=50\ [mi/hr]+37.5\ [mi/hr]=87.5\ [mi/hr]$

$v_1=60\ (mi)/(h)\n\nt_1=8.0\ s=(8)/(3600)\ h=(1)/(450)\ h\n--------------\na=(v)/(t)\n\na=(60)/((1)/(450))\ (mi)/(h^2)=27000\ (mi)/(h^2)\n--------------\nv_o=50\ (mi)/(h)\n\nt=5.0\ s=(5)/(3600)\ h=(1)/(720)\ h\n--------------$

$v=v_o+at\n\n\nv=50\ (mi)/(h)+27000\ (mi)/(h^2)\cdot(1)/(720)\ h=50\ (mi)/(h)+37.5\ (mi)/(h)=87.5\ (mi)/(h)\leftarrow Answer$
