Rounded to the nearest whole number, how many neutrons, on average, are in an atom of osmium?

Physics

Answer: 114

Explanation:

Osmium: It is hard, brittle transition metal.

Chemical symbol: Os

Atomic number, Z = 76

Number of protons = Atomic number = 76

Mass Number, A = 190.23 ≈ 190

Mass number = number of protons + number of neutrons

⇒190 = 76 + n

⇒n = 190 - 76

⇒n = 114

Thus, the atomic number of an atom of Osmium is 114.

Answer: 114

Explanation:

The mass number of an element gives the sum of the protons and the neutrons inside the nucleus of one atom of that element, while the atomic number of an element gives the number of protons inside one atom of that element.

We can infer the number of neutrons inside one atom of Osmium from its mass number and atomic number.

The atomic number of osmium is 76, so each atom of osmium has 76 protons

The (average) mass number of osmium is 190, so each atom of osmium has (on average) 190 protons+neutrons

So, in order to find the average number of neutrons, we can subtract the atomic number from the mass number:

N=A-Z=190-76=114

(c) Conservation of angular momentum

(d) Conservation of kinetic energy

(e) None of these

Conservation of angular momentum

Answer: Option C.

<u>Explanation:</u>

The law of conservation of angular momentum expresses that when no outer torque follows up on an article, no difference in precise force will happen.

The law of conservation of angular momentum expresses that the angular energy of a body that is the result of its snapshot of latency about the hub of revolution and its rakish speed about a similar pivot, can't change except if an outside torque follows up on the framework.

Identify forces between two objects which are inversely proportional to the square of the distance between them. i. nuclear forc
nikdorinn [45]
The force between two celestial bodies is a Newtonian gravitational force. 
It is also called Newton's law of universal gravitation. We can write it down mathematically in the following way:
F=G \frac{ m_{1} m_{2} }{ r^{2}}
We can see from this formula that gravitational force is <span>inversely proportional to the square of the distance between bodies.
The electrostatic force between two charges is Coulombs force. We can write it down like this: 
</span>F= k_{e} \frac{ q_{1} q_{2} }{ r^{2}}
This force is also inversely proportional to the square of the distance between interacting particles.
The nuclear force is a little bit more complicated. It can be expressed using the so-called Yukawa potential, which has the following form:
V_{y} =- g^{2} \frac{ e^{-ur} }{r}
This interaction does not follow the inverse-square law.
The final answer should be 8.

Answer: the potental with twice larger radius 0.5* Vo ( being Vo =100V)

Explanation: In order to solve this proble, we know that teh potential due to charged sphere relative V=0 at infinity,  we have

Vo=k*Q/R  where R is the sphere radius

if we enlarge the radius to 2R the

V= k*Q/2*R = Vo/2
