Explanation:
When a solution is saturated it means, No more solute can dissolve in solvent
Answer:
Explanation: Becouse she was no longer attractive thus the reason
If we consider Boyles law for gases, it states the following equation,
PV/T =k
where k is a constant
P-pressure, T- temperature and V -volume
the volume is constant at both situations as its a rigid tank as mentioned in the questions.
Therefore we consider Volume to be constant , then equation is
P/T = kV
kV = c (new constant)
P/T = c
P = cT
Therefore pressure is inversely proportional to temperature, whatever change in pressure would cause the same kind of change in temperature as well.
therefore when T decreases, P also decreases.
Answer is B
Answer:
takes longer than 365 days to orbit the sun
has seasons because of a tilted axis
Note: We see 365 days for a year - from an external point of view, a year would take 366 days to orbit the sun - this is because it takes slightly less than 24 hours from sunrise to sunrise because of the rotation of the earth about the sun (a sidereal year is 366 days as compared to 365 days observed on earth)
Answer:
Explanation: Two possible solutions
in the absence of friction
mgh = ½mv²
h = v²/2g = 24.4²(2(9.81) = 30.344... = 30.3 m
if enough rolling friction exists to keep the ball from sliding, but ignoring air resistance and assuming the ball is already rolling smoothly at the start
mgh = ½mv² + ½Iω²
mgh = ½mv² + ½((2/3)mR²)(v/R)²
2gh = v² + (2/3)v²
2gh = (5/3)v²
h = (5/6)v²/g
h = (5/6)24.4²/9.81 = 50.5742 = 50.6 m
