Heterogeneous mixture is a substance that does not have a chemical formula and has more than one fase and the examples are water and oil because of the two different colors of fases, italian dressing is also another example because it has more than one different colors of fases.
Answer:
L = 1.11 x m, is the length of piece of 20 cm wide Aluminum foil to make capacitor large enough to hold 52000 J of energy.
Explanation:
Solution:
Data Given:
Heat Energy = 52000 J
Dielectric Constant of the plastic Bag = 3.7 = K
Thickness = 2.6 x m =d
V = 610 volts
A = width x Length
width = 20 cm = 20 x m
Length = ?
So,
we know that,
U = 1/2 C Δ
U = 52000 J
C = ?
V = 610 volts'
So,
U = 1/2 C Δ
52000 J = (0.5) x (C) x ()
C = 0.28 F
And we also know that,
C =
E = 8.85 x
K = 3.7
A = 0.20 x L
d = 2.6 x m
Plugging in the values into the formula, we get:
0.28 =
Solving for L, we get:
L = 1.11 x m,
is the length of piece of 20 cm wide Aluminum foil to make capacitor large enough to hold 52000 J of energy.
Answer:
\Delta E=1.22\times 10^{-22}J
Explanation:
The energy of electron in any state is given by here h is planck's constant n is state of electron L is the infinte potential well m is the mass of electron
We know that
Potential well dimension =
Mass of electron
So energy required to electron to jump from ground state to 3rd state
