Answer:
A small positively charged nucleus surrounded by revolving negatively charged electrons in fixed orbits
Answer:
B
Explanation:
it is B because in order to have kinetic energy the object has to be in motion, because if it wasnt in motion and sitting on the hill then it has potentail energy, hope this helps
Answer:
R aluminium = 2.63x10^-6 Ω*cm
Rcopper = 1.7 x10^-6 Ω*cm
I would use Cu as interconnections in advanced CMOS nodes.
Explanation:
the conductivity formula equals:
σ = n*g*u
n = carrier concentration
u = mobility
g = charge of carrier
The resistivity is equal to:
R = 1/σ
For the aluminium, we have:
g = 1.602x10^-19 C
R = 1/(1.98x10^23 * 1.602x10^-19 * 12 = 2.63x10^-6 Ω*cm
For copper:
R = 1/(8.5x10^22 * 1.602x10^-19 * 43.2) = 1.7 x10^-6 Ω*cm
According to the calculations found for both resistivities, I would use Cu as interconnections in advanced CMOS nodes, since copper has a lower resistivity and therefore, copper conducts electricity better.
Answer:
If two forces act on an object in the same direction, the net force is equal to the sum of the two forces. This always results in a stronger force than either of the individual forces alone
<span>Colloid is a type of mixture that scatters light and cannot be filtered. Colloids are heterogeneous mixtures with a particle size between that of the solutions and that of the suspensions: the size of the particles of a colloid is bigger than the molecules or ions of a solution and smaller than the particles of a suspension. Due to the small size of the particles in the colloids, the diluted colloids seem homogeneous, but those particles are big enough to produce the Tyndall effect, which is the dispersion of the light. Solutions do not show Tyndall effect.</span>
