Answer:
C.Supersaturated
Explanation:
There are three types of solution:
<u>SATURATED SOLUTION</u>:
It is the solution that contains maximum amount of solute dissolved in a solution in normal conditions.
<u>UNSATURATED SOLUTION</u>:
It is the solution that contains less than the maximum amount of solute dissolved in a solution in normal conditions. It has space for more solute to be dissolved in it.
<u>SUPERSATURATED SOLUTION:</u>
It contains more than the maximum amount of solute dissolved in it. Such a solution has no capacity to dissolve any more solute under any conditions.
Since the sugar is no more dissolving in the tea and has settled down. Therefore, the solution is:
<u>C.Supersaturated</u>
Answer:
253 years
Explanation:
a = Distance in Astronomical units from the sun = 40 AU
P = Orbital period in years
From Kepler's law we have
The orbital period of the Kuiper belt object is 253 years.
The solution for this problem is:
v = sqrt(T/µ) where T = m*g = 4*g and µ = 0.0055/2.5 = 0.0022kg/m
Now L = 2 m
For a string the frequencies are n*v/2L
so n*v/2L = 64 and (n+1)*v/2L = 80
Now eqn 2 divided by eqn 1 yields (n + 1)/n = 80/64 = 1.25
=> 1.25 n = n + 1 or .25n = 1 or n = 4
now subbing back into eqn 1 we have 4*v/2L = 64 or v = 32*L = 32*1.9 = 60.8
So 60.8= sqrt(1.1*g/0.0022)
so 1.1*g = 60.8^2*0.0022 = > g = 60.8^2*0.0022/1.1 = 7.39 m/s^2
Indications of a possible volcanic eruption are visible gases, ground deformation and tremors.
The energy in a firecracker is completely chemical energy, in the gunpowder
or whatever else it's loaded with. When that powder burns, the smoke and hot
gas creates high pressure inside the can, which eventually blows the can open,
blowing out all the little burning grains of powder, and sending a shock wave out
through the surrounding air to make the 'POP'. So you have the chemical energy
released as heat, kinetic energy of all the fragments that fly out, and electromagnetic
energy of the heat and the visible light. That looks like Choice-'D'.
