Emf e = 11
r 1 = 3.0
r 2 = 3.0
r 3 = ?

The two in parallel are equivalent to 3 • 3/6 = 1.5 Ω
To have 2.4 volts across them, the current is I = 2.4/1.5 = 1.6 amps. and the unknown R = (11–2.4) / 1.6 = 5.375 Ω or 5.4 Ω

A piston-cylinder device initially contains 0.3 kg of nitrogen gas at 160 kPa and 140oC. The nitrogen is now expanded isothermal

irakobra [83]

Answer:

<h2>Work done by the gas is given as</h2><h2> $W = 1.72 \times 10^4 J$ </h2>

Explanation:

As we know that the process is isothermal so here work done is given as

$W = nRTln(\frac{P_1}{P_2})$

here we know that

$n = \frac{w}{M}$

$n = \frac{300}{28} = 10.7 moles$

now we have

$W = 10.7 (8.31)(273 + 140) ln(\frac{160}{100})$

so we have

$W = 1.72 \times 10^4 J$
