Explanation:
Q=mc(T2-T1)
or
q = mcΔT ,
where m is the mass of the sample,
c is the specific heat,
and ΔT is the temperature change.
Q=2.0 × 2000 × 5
Q=20000J⋅kg −1 ⋅K −1
I hoped I helped pls rate as brainliest
Answer:
Condensation
Explanation:
Increased pressure is called condensation or compressions because they are regions of high air pressure whilst rarefractions are low air pressure.
Answer:
relates the electric field at points on a closed surface to the net charge enclosed by that surface.
Explanation:
Gauss Law states that overall electric flux of a closed surface is equivalent right to charge enclosed which is divided by the permittivity. In other words Gauss Law stress that
net electric flux that pass through an hypothetical closed surface is equivalent to overall electric charge present within that closed surface.
The Gauss law can be expressed mathematically as
ϕ = (Q/ϵ0)
Q = total charge within the surface,
ε0 = the electric constant
Answer:
λ = h/p
<u>
</u>
This energy is equivalent to E=150.44eV
Explanation:
<u>de Broglie Equation:</u>
λ = h/p
h=6.63×10-34 m2 kg / s Planck's constant
so: p=h/λ
On the other hand, an atomic distance, an angstrom, is equal:
, λ should be similar to this distance.
<u>Kinetics Energy of a electron, m=9.11×10−31 kg</u>
<u>
</u>
<u>Number of volts needed to accelerate that electron from rest to this energy:</u>
So, this energy is equivalent to E=150.44eV
This high-voltage device is called: particles accelerator
