Part 1- An ideal gas, initially at a volume of 1.71429 L and pressure of 7 kPa, undergoes isothermal expansion until its volume
Musya8 [376]

Part 1- The work done by the gas during this process will be 5.65 ×10⁻³ kJ.

Part 2-The heat added to the gas during this process will be 5.65 ×10×10⁻³ kJ.

<h3>What is work done by the gas?</h3>

Work is the product of pressure p and volumes V during a volume change for such a gas. The work seems to be the area under the curve that indicates how the state changes.

The work done under the isothermal process is;

\rm W= P_1V_1 log_e(\frac{P_1}{P_2} )\\\\ W= 7 \times 1.71429  \times 10^{-3} log_e(\frac{7 }{2} )\\\\\ W= 0.0044 \  kJ

For the isothermal process;

ΔU=0

\rm \triangle Q = \triangle E + \triangle W \\\\ Q =  0 + 5.65 \times 10^{-3}\\\\ Q = 5.65 \TIMES 10^{-3} \ kJ

Hence, the work done, and the heat added by the gas during this process will be 5.65 ×10⁻³ kJ and 5.65 ×10×10⁻³ kJ respectively.

Cuántas veces es mayor la masa del protón que la del electrón?
viktelen [127]

Answer:

Un protón es aproximadamente 1835 veces más masivo que un electrón. Si está preguntando acerca de sus dimensiones físicas, nadie lo sabe. Los científicos actualmente no saben qué tan pequeños son los electrones. ¡Son más pequeños de lo que podemos medir actualmente y pueden no tener un tamaño en absoluto!

If a teacher had 48 red pens and the ratio of red to blue pens she owns is 6:1, she will have a total of 56 pens

Let the number of red pens be R and the number of blue pens be B.

R = 48

R / B = 6 / 1

48 / B = 6 / 1

B = 48 / 6

B = 8

Total number of pens = Number of red pens + Number of blue pens

Total number of pens = R + B

Total number of pens = 48 + 8

Total number of pens = 56 pens

Therefore, she has a total of 56 pens

A light platform is suspended from the ceiling by a spring. A student with a mass of 90 kg climbs onto the platform. When it sto
Ilya [14]
Refer to the diagram shown.

When the student climbs onto the platform, the spring stretches by 0.82 m to reach the equilibrium position.
The mass of the student is m = 90 kg, so his weight is
mg = (90 kg)*(9.8 m/s²) = 882 N

By definition, the spring constant is
k = (882 N)/(0.82 m) = 1075.6 N/m

When the spring is stretched by x from the equilibrium position, the restoring force is
F = - k*x.

If damping is ignored, the equation of motion is
F = m * acceleration
or
m \frac{d^{2}x}{dt^{2}} = -kx \\ \frac{d^{2}x}{dt^{2}} + \frac{k}{m} x = 0

Define ω² = k/m = 11.751 => ω = 3.457.
Then the solution of the ODE is
x(t) = c₁ cos(ωt) + c₂ sin(ωt)

x'(t) = -c₁ω sin(ωwt) + c₂ω cos(ωt)
When t=0, x' =0, therefore c₂ = 0

The solution is of the form
x(t) = c₁ cos(ωt)
When t = 0, x = 0.32 m. Therefore c₁ = 0.32

The motion is
x(t) = 0.32 cos(3.457t)
The single amplitude is 0.32 m, and the double amplitude is 0.64 m.

Answer: 
0.32 m (single amplitude), or
0.64 m (double amplitude)
