A quantity y is to be determined from the equation y=(px)/q^2

What is the effect of the following change on the volume of 1 mol of an ideal gas? The initial pressure is 722 torr, the final p

Ray Of Light [21]

Answer:

A. Volume is unchanged

Explanation:

$P_{i}$ = initial pressure of the gas = 722 torr = 96258.7 pa

$P_{f}$ = final pressure of the gas = 0.950 atm = 96258.75 pa

$T_{i}$ = initial temperature = 32 °F = 272.15 K

$T_{f}$ = final temperature = 273 K

$V_{i}$ = initial volume

$V_{f}$ = final volume

Using the Equation

$\frac{P_{i} V_{i}}{T_{i}} = \frac{P_{f} V_{f}}{T_{f}}$

Inserting the values

$\frac{(96958.7) V_{i}}{272.15} = \frac{(96958.75) V_{f}}{273}$

$V_{f} = (1.00312) V_{i}$

Hence the volume is unchanged.

A 20 watt lightbulb uses 20 Joules of energy every second.A person expends 50 watts of energy per stair when climbing up stairs.

Pachacha [2.7K]

20W = 20 J/s

Energy expended during climbing stairs = 50 W of energy/stair = 50J/stair

For 20 stairs, Total energy = 50x20 = 1000 J

This can light bulbs for, T= 1000J/20 J/s =50 seconds

Two resistors of 5.0 and 9.0 ohm are connected in parallel. A 4.0 ohm resistor is then connected in series with the parallel com

rewona [7]

Answer:

I1 = 0.772 A

Explanation:

Given: R1 = 5.0 ohm, R2 = 9.0 ohm, R3 = 4.0 ohm, V = 6.0 Volts

To find: current I = ? A

Solution:

Ohm's law V= I R

⇒ I = V / R

In order to find R (total) we first find R (p) fro parallel combination. so

1 / R (p) = 1 / R1 + 1/ R2 ∴(P) stand for parallel

R (p) = R1R2 / ( R1 + R2)

R (p) = (5.0 × 9.0) / (5.0 + 9.0)

R (p) = 3.214 ohm

Now R (total) = R (p) + R3 (as R3 is connected in series)

R (total) = 3.214 ohm + 4.0 Ohm

R (total) = 7.214 ohm

now I (total) = 7.214 ohm / 6.0 Volts

I (total) = 1.202 A

This the total current supplied by 6 volts battery.

as voltage drop across R (p) = V = R (p) × I (total)

V (p) = 3.214 ohm × 1.202 A = 3.864 volts

Now current through 5 ohms resister is I1 = V (P) / R1

I1 = 3.864 volts / 5 ohm

I1 = 0.772 A
