One major difference between osmosis and diffusion is that diffusion
does not need a semipermeable membrane
does not take place in living tissues
takes place only in a liquid medium
takes place only in a gaseous medium
cannot be demonstrated experimentally

13.9 Ω
8.9 Ω
6.8 Ω
3.2 Ω
1.8 Ω
Correct answer is C
\(\frac{\theta}{100} = \frac{R_ {\theta} - R_0}{R_{100} - R_0}\)
\(\frac{45}{100} = \frac{R_{\theta} - 5}{9 - 5}\)
\(45 \times 4 = 100(R_{\theta} - 5)\)
\(180 = 100R_{\theta} - 500\)
\(180 + 500 = 100R_{\theta}\)
\(R_{\theta} = \frac{680}{100}\)
\(R_{\theta} = 6.8 \Omega\)

Correct answer is C
where f = \(\frac{oscillations}{time}\)
period = 1/ f or \(\frac{time}{oscillations}\)
For pendulum x:
where period = 1.5 and oscillation = 400
time = oscillations X 1.5 = 600s
For pendulum y:
\(\frac{time}{oscillations}\) → 600/500
period for y = 1.2s
period =
