Answer:
a new chromebook for you and you will get to know the other one that
The subatomic particles that acts like a mini-magnet is electron. Electrons are negatively charged sub atomic particles in an atom. The electron spin is a property of an electron that makes it behave like it's spinning; a spinning electron produces a magnetic field that makes it behave like a tiny magnet in an atom.
Answer:
C) Pressure will compress a gas, reducing its volume and giving it a greater density and concentration of particles.
Explanation:
At constant temperature, pressure and volume are inversely related.
P V = constant

As the pressure increases, the gas compresses, the particles come closer reducing the volume of gas.
As we know, with decrease in volume, density increases.


Thus, the pressure of a gas is directly related to concentration of particles. Increase in pressure causes increase in concentration of the particles.
I think the answer is CuF2
Answer:
46.22 cm
Explanation:
The focal refraction, fr is given by
The focal red light is given by


and making fr the subject we obtain

fv = 0.945455* 16.70886 cm = 15.79747 cm

Therefore, violet image is approximately 46.22 cm
