Answer:
Similarities:
Both are based on developments in quantum mechanics, both involve a centrally located mass of protons and neutrons (nucleus)
Differences:
nucleus: Electrons distinct and follow a definite orbit around nucleus
Cloud: No definite orbit for electrons around nucleus, only probability distributions of where electron is likely to be.
Answer:
55,42 J
Explanation:
Since the height of the room is 3.45 m (distance between the floor and the ceiling) the difference between this value and the length of the rope 1.19 m; it will be equal to (3.45-1.19) =2.26 m. If we take as a reference point (Ep=0) the floor of the room, then the potential energy will be equal to Ep = M * g * h, replacing values in this equation (2.5 kg * 9.81 m/s2 * 2.26 m) will be 55,42 (N * m) or Jules.
Answer:
I) You walk barefoot on the hot street and it burns your toes.
II) When you get into a car with hot black leather in the middle of the summer and your skin starts to get burned.
Explanation:
In conduction mode of heat transfer we know that the energy is transferred from one system to other system due to direct contact of two bodies
Here due to this direct contact the energy is transferred via a given solid or liquid medium
In this type of heat transfer medium particles will remain in its own position only the energy is transferred.
So here we can say the correct answer will be
I) You walk barefoot on the hot street and it burns your toes.
II) When you get into a car with hot black leather in the middle of the summer and your skin starts to get burned.

There are warnings about using your cell phone while pumping gas because cell phone batteries can explode.
<h3>What is pumping gas?</h3>
When the vehicle is not having enough fuel to drive more miles, it needs to be fueled by petrol, diesel or natural gas. This is called pumping gas.
According to the rules of National Fire Protection Association, No one is allowed to use any type of electronic items while pumping gas. So, the cell phone is not allowed.
Phones develop static charge. It is believed that cell phone batteries can explode while pumping gas. It would be a real danger.
Thus, there are warnings about using your cell phone while pumping gas because cell phone batteries can explode.
