3 0

Answer:

orbital 3 also called orbital f

Explanation:

In the resolution of the Schrödinger equation for the three-dimensional hydrogen atom with spherical coordinates three constants appear, which are related, these constants are called quantum numbers.

The first one is the number n called the main quantum number and its value ranges from to infinity

The second number is called the orbital quantum number (l) and has values from zero to n-1

The third number corresponds to the magnetic orbital quantum number and thymus values from –l to l

Let us apply to our case, state (5, 3, 0) corresponds to a state in period 5 of

the quantum number, with orbital 3 also called orbital f and with magnetic number 0 that e spherical

f a car is speeding down a road at 40 miles/hour (mph), how long is the stopping distance D40 compared to the stopping distance

Oksana_A [137]

Answer:

D40 = 2.56 × D25

so number is 2.56 multiple of stopping distance @ 25 mph

Explanation:

given data

speed = 40 miles / hour

distance = D40

speed limit = 25 miles / hour

distance = D25

to find out

express number a multiple of stopping distance @ 25 mph

solution

we know here stopping distance is directly proportional to (speed)²

so here speed ratio is

initial speed = $\frac{40}{25}$

so initial speed = 1.6

stopping distance increase = (1.6)²

$\frac{D40}{D25}$ = (1.6)²

$\frac{D40}{D25}$ = 2.56

so here

D40 = 2.56 × D25

so number is 2.56 multiple of stopping distance @ 25 mph

List the charge, location, and mass of a proton, a neutron,<br> and an electron.

Atoms consist of protons, neutrons and electrons

Explanation:

There are three particles in an atom:

Proton: it is located in the nucleus. Its mass is $m_p = 1.6726\cdot 10^{-27}kg$ , and it is positively charged (its electric charge is $+1.6\cdot 10^{-19}C$ , also called fundamental charge)
Neutron: it is also located in the nucleus. Its mass is slightly larger than the proton ( $m_n = 1.6749\cdot 10^{-27}kg$ ), and it has no electric charge. Protons and neutrons are held together inside the nucleus by the strong nuclear interaction
Electron: it is located outside the nucleus, in a region called "electron cloud". According to quantum mechanics, its exact position cannot be determined, but it can only be described by a "wave function" which gives the probability of finding the electron at a certain position. Its mass is much smaller than the proton ( $m_e = 9.11\cdot 10^{-31} kg$ ) and it is negatively charged (its charge is the opposite of that of the proton: $-1.6\cdot 10^{-19}C$ ).
