Answer:
D. TA < TB
Explanation:
From general gas equation, we know that:
PV = nRT
PV/R = nT
where,
P = pressure of gas
V = volume of gas
R = General gas constant
T = temperature of gas
n = no. of moles of gas
<u>FOR CYLINDER A</u>:
PV/R = (nA)(TA) _____ eqn (1)
<u>FOR CYLINDER B</u>:
PV/R = (nB)(TB) _____ eqn (2)
Because, Pressure, Volume are constant for both cylinders.
Comparing eqn (1) and (2)
(nA)(TA) = (nB)(TB)
It is given that the amount of gas in cylinder A is twice as much as the gas in cylinder B. This means the number moles in cylinder A are twice as much as no. of moles in cylinder B.
nA = 2(nB)
using this in eqn:
2(nB)(TA) = (nB)(TB)
TA = (1/2)(TB)
<u>TA = 0.5 TB</u>
Therefore it is clear that the correct option is:
<u>D. TA<TB</u>
Answer:
A theory is a system of ideas intended to explain something, and a hypothesis is an educated guess.
Explanation: Hope this Helps! :)
The speed of the wave is given by Distance divided by time.
Speed = 10.9/5.1
= 2.14 m/s
But; speed is also given by frequency multiplied by wavelength
Wavelength is 4 m( distance between two successive crests)
thus; 2.14 = 4 × f
f = 2.14/4
= 0.535 Hz
