What roles do exchange particles play in an interaction?

Answers

Answer 1

Answer:

The exchange particles you are talking about are probably the gauge bosons. They are elementary bosons, meaning that they are elementary particles making part of the standard model and they have integer spin. There are four of them: The photon, the gluon, the W+ and W- bosons and the Z boson. The photon basically is the particle of light being an excitation, if you will, of the electromagnetic field so that is mediates the electromagnetic force. The only thing that differs from long range photons (light) is that they are what is called virtual photons but that is for another subject. Then you have the gluons that come in 8 varieties and their role is to interchange the color charge in between quarks so that it mediates the strong nuclear force, the force that keeps quarks bounded into protons. And then finally there are the W+, W- and Z bosons that mediates this time, the weak nulear force, the force that allows protons to coexist in the nucleus of atoms with neutrons. I hope that helped you, but as i usually do, i tried to simplify my answer beacause i could have written a lot mor about that!

a stone is dropped from the top of 50 m high tower simultaneously another stone is thrown upward with a speed of 20 m/s . calculate the time at which both the stones cross each other

Answers

'H' = height at any time
'T' = time after both actions
'G' = acceleration of gravity
'S' = speed at the beginning of time
Let's call 'up' the positive direction.
Let's assume that the tossed stone is tossed from the ground, not from the tower.

For the stone dropped from the 50m tower:

H = +50 - (1/2) G T²

For the stone tossed upward from the ground:

H = +20T - (1/2) G T²

When the stones' paths cross, their Heights are equal.

50 - (1/2) G T² = 20T - (1/2) G T²

Wow ! Look at that ! Add (1/2) G T² to each side of that equation,
and all we have left is:

50 = 20T Isn't that incredible ? ! ?

Divide each side by 20 :

2.5 = T

The stones meet in the air 2.5 seconds after the drop/toss.

I want to see something:
What is their height, and what is the tossed stone doing, when they meet ?

Their height is +50 - (1/2) G T² = 19.375 meters

The speed of the tossed stone is +20 - (1/2) G T = +7.75 m/s ... still moving up.
I wanted to see whether the tossed stone had reached the peak of the toss,
and was falling when the dropped stone overtook it. The answer is no ... the
dropped stone was still moving up at 7.75 m/s when it met the dropped one.

A 12 volt car battery produces more current than a 1.5 volt battery for a TV remote because...A. the tv remote has more kinetic energy.
B. the tv remote has a greater difference in electric potential energy.
C. the car bettery has a greater difference in electric potential energy.
D. the car bettery has more kinetic energy.

Answers

This question is loaded with misleading, marginally meaningful phrases.

A 12V battery produces more current than a 1.5V battery produces,
through the same device, because the potential difference between
the terminals of the 12V battery is 8 times the potential difference
between the terminals of the 1.5V battery.

Of the choices offered, choice 'C' is the closest. But it should say
"electrical potential", NOT "potential energy".

Final answer:

A 12-volt car battery produces more current than a 1.5-volt TV remote battery because it has a greater difference in electric potential energy, resulting in a larger 'push' of electrons and therefore a larger current.

Explanation:

A 12-volt car battery produces more current than a 1.5 volt battery for a TV remote because the car battery has a greater difference in electric potential energy. The electric potential energy is related to the voltage of the battery, or the 'push' it provides to move electrons through a circuit. A higher voltage means a greater 'push' and thus, more current. This is evidenced by the fact that car batteries are designed to start cars, which requires a larger current than operating a TV remote.

Which particles make up the nucleus of an atom?

Answers

The particles that make up the nucleus of an atom are protons and neutrons.

The nucleus of an atom is composed of two main types of subatomic particles: protons and neutrons. Protons have a positive electric charge, while neutrons have no electric charge, making them neutral. These particles are relatively heavy compared to electrons, which orbit the nucleus.

The protons and neutrons are held together tightly in the nucleus by a strong force called the nuclear force or strong nuclear force. This force overcomes the repulsive force between positively charged protons, keeping the nucleus stable.

The number of protons in the nucleus determines the element's identity. For example, if an atom has one proton, it's hydrogen; if it has six protons, it's carbon, and so on. This number is called the atomic number. The sum of protons and neutrons in the nucleus is called the mass number.

Which one of the following accurately describes the force of gravity

Answers

The force of gravity, also called gravitational force, is the force exerted by the gravity of one object to another object near it. This is dependent on factors like mass of the two objects measured between their centers.
