Answer:

Facilitated diffusion.

Explanation:

Facilitated diffusion is the movement of molecules across a biological cell membrane by the use of a membrane protein.

It is a spontaneous passive movement and it can also be reffered to as FACILITATED TRANSPORT or PASSIVE-MEDIATED TRANSPORT.

A gas undergoes two processes. In the first, the volume remains constant at 0.170 m3 and the pressure increases from 1.50×105 Pa

Mnenie [13.5K]

Answer:

$W_{T} = - 24 kJ$

Explanation:

The work (W) done by the gas can be calculated using the following equation:

$W = p*\Delta V = p*(V_{f} - V_{i})$

Where:

p: is the pressure

[tex}V_{f}[/tex]: is the final volume

[tex}V_{i}[/tex]: is the initial volume

In the first process, the work done by the gas is:

$W_{1} = p*\Delta V = p*0 = 0$

Since the volume remains constant, the total work done by the gas is equal to zero.

In the second process, the work done by the gas is:

$W_{2} = p*(V_{f} - V_{i}) = 6.00 \cdot 10^{5} Pa*(0.130 m^{3} - 0.170 m^{3}) = -24 kJ$

Now, the total work done by the gas during both processes is:

$W_{T} = W_{1} + W_{2} = 0 + (-24 kJ) = - 24 kJ$

Therefore, the total work done by the gas during both processes is - 24 kJ.

I hope it helps you!

A compass originally points North; at this location the horizontal component of the Earth's magnetic field has a magnitude of 2e

astraxan [27]

Answer:

μ =5.40 A-m²

Explanation:

The components of the net magnetic field are the magnetic field of the dipole and the magnetic field of Earth, then from the right triangle, the deflection angle is computed by

tan θ = Bdipole / Bearth ⇒ Bdipole = Bearth* tan θ

Bdipole = 2e-5 T*tan 70° = 5.49e-5 T

The magnetic field at the location of the compass due to the dipole has a magnitude

Bdipole = (μ₀/4π)(2μ/r³) ⇒ μ = Bdipole r³ / 2(μ₀/4π)

μ = (5.49e-5 T)(0.27m)³ / 2(1 × 10−7 T m² /(C m/s)) = 5.40 A-m²
