Answer: The volume of an ideal gas will triple in value if the pressure is reduced to one-third of its initial value
Explanation:
We can determine this from the gas laws. Using Boyle's law, which states that "the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature"
Mathematically, P ∝ (1/V)
Since P ∝ (1/V), we can then write that
P = k(1/V)
Where P is the pressure, V is the volume and k is the proportionality constant
PV = k
We can then write that
P1V1 = P2V2 = P3V3 = ...
Hence, P1V1 = P2V2
Where P1 is the initial pressure of the gas
P2 is the final pressure of the gas
V1 is the initial volume of the gas
and V2 is the final volume of the gas
From the question, we want to determine what will make the new volume be thrice the initial volume.
Hence,
P1 = P
V1 = V
P2= ??
V2 = 3V
Therefore,
P × V = P2 × (3V)
P2 = PV/3V
P2 = P/3 = 1/3(P)
This means the volume of an ideal gas will triple in value if the pressure is reduced to one-third of its initial value
At the "very top" of the ball's path, there's a tiny instant when the ball
is changing from "going up" to "going down". At that exact tiny instant,
its vertical speed is zero.
You can't go from "rising" to "falling" without passing through "zero vertical
speed", at least for an instant. It makes sense, and it feels right, but that's
not good enough in real Math. There's a big, serious, important formal law
in Calculus that says it. I think Newton may have been the one to prove it,
and it's named for him.
By the way ... it doesn't matter what the football's launch angle was,
or how hard it was kicked, or what its speed was off the punter's toe,
or how high it went, or what color it is, or who it belongs to, or even
whether it's full to the correct regulation air pressure. Its vertical speed
is still zero at the very top of its path, as it's turning around and starting
to fall.
Answer:
Explanation:
given,
speed of the car = 46.4 m/s
Radius of the curve = 52.3 m
banked at an angle = θ = ?
now car is moving in the circular path
so,

Available Options Are:
A.SALT
B.STONE
C.GHEE
D.SPONGE
Answer:
Option A. Salt
Explanation:
The reason is that the all of the grains of salt are not in a unified shape. Some of these have large shape, some has small shape and the best think is that their shape doesn't resemble with each other. This is also because that the salt includes many other ingrediants that form part of the grain. Hence Salt is the correct Option.
Stone has a unified pattern shape hence it doesn't have irregular pattern.
Ghee also has unified shape pattern due to one compound existence and also because of liquid particles that has highest rate of reqular patterns.
Sponge is a compound product and has one compound existence thus the pattern of the particles will be regular.
