Answer:

V = 0.248 L

Explanation:

To do this, use the following equation:

P1*V1/T1 = P2*V2/T2

This equation is used to find a relation between two differents conditions of a same gas, which is this case. From this equation we can solve for V2.

Solving for V2:

V2 = P1*V1*T2/T1*P2

Temperature must be at Kelvin, so, we have to sum the temperature 273 to convert it in K.

Replacing the data we have:

V2 = 1 * 4.91 * (-196+273) / 5.2 * (20+273)

V2 = 378.07 / 1523.6

V2 = 0.248 L

What us a magnetic domain?​
julsineya [31]

magnetic domain is a region within a magnetic material in which the magnetization is in a uniform direction. This means that the individual magnetic moments of the atoms are aligned with one another and they point in the same direction.

The diagram shows a positive charge moving in a magnetic field. a field of circles labeled b. there is a positively charged part
lesya692 [45]

The magnetic force will be point upwards in perpendicular direction to the field.

<h3>What is the direction of magnetic force?</h3>

The direction of the magnetic force on negative charge occurs in the opposite direction while it is directed to the positive charge direction.

From the given image and description, the positively charged particle with a velocity vector, v is pointing left, thus we can conclude that the magnetic force will be point upwards in perpendicular direction to the field.

Explain Quantum physics in a summarised, simple way. Thanks!
Nimfa-mama [501]

Answer:

Quantum mechanics was one of the two great revolutions in modern physics. The first, or Einstein's relativity, was in fact the pinnacle of classical physics. But quantum mechanics and related theories completely changed the world of science and philosophy, and it was the end of classical physics.

Like Einstein relativity, we all use quantum mechanics on a daily basis, but its mathematical principles are very complex and beyond the reach of ordinary people without a degree in physics or mathematics.

In this post, I have tried to make this theory more accessible to all interested loved ones by stating the quantum theory and its consequences for the public.

An electric field of 260000 N/C points due west at a certain spot. What is the magnitude of the force that acts on a charge of -
olga55 [171]

Answer:

Electric force on the charge will be equal to -1742000 N

Explanation:

We have given electric field at a point is E = 260000 N/C

And charge q = -6.7 C

We have to find the force on that charge

Force on the charge is equal to Force = charge × electric field ( multiplication of electric field and charge )

So force will be equal to F=260000\times -6.7=-1742000N

So electric force on the charge will be equal to -1742000 N
