In the nucleus of all atoms are sub-atomic particles called protons and neutrons. all protons have a positive charge. since all

like-charged particles repel each other, you would logically conclude that protons could not stay in close proximity to each other in an atom's nucleus. how do you explain the fact that protons stay close together in the nucleus?

Protons stay close together in the nucleus because the strong nuclear force.


There are four natural elemental forces: 1) gravity, 2) electromagnetic force, 3) weak nuclear force, and 4) strong nuclear force.


Gravity is an attractive force. It acts at long distance and is proportion to the product of the masses. It is not relevant in the nucleous of an atoms because the masses are tiny.


Electrotmagnetic force may be attractive or repulsive. Indeed, as stated since the protons have all positive charge, this force is repulsive, and you could expect that they the protons cannot stand so close to each other in the nucleous.


Strong nuclear force is the strongest of the four forces in nature and acts only to very short distances. It is the atractive force between the partilces in the atom nuclei. This force overcomes the electromagnetic repulsion between the protons. This force is responsible for keeping the protons and the neutrons together in the nuclei.

The radiations detected by Arno Penzias and Robert Wilson
were the original heat from the Big Bang.

Today, we call those waves the "Cosmic Microwave Background".

I'm not sure, but I think those guys were awarded a Nobel Prize in Physics
for that discovery.

A small electric motor produces a force of 5 N that moves a remote-control car 5 m every second. How much power does the motor p
kati45 [8]

Answer:

Explanation:

Given:

Force, f = 5 N

Velocity, v = 5 m/s

Power, p = energy/time

Energy = mass × acceleration × distance

Poer, p = force × velocity

= 5 × 5

= 25 W.

Note 1 watt = 0.00134 horsepower

But 25 watt,

0.00134 hp/1 watt × 25 watt

= 0.0335 hp.

When you lift an object, you add the energy of lifting to the object.<br> Tor F
PtichkaEL [24]

It's true, when we lift an object we add energy to it.

because, when we lift an object by applying force , the object attains a height and hence the energy gets stored in it, in the form gravitational potential energy .
