A reaction taking place in a container with a piston-cylinder assembly absorbs 4850. J of heat and has a change in the internal
Maslowich

Answer:

V_f = 16.3 Ltr

Explanation:

As per first law of thermodynamics we know that

heat absorbed = change in internal energy + Work done

so we have

Heat = 4850 J

\Delta U = 1618.5 J

so work done is given as

4850 = 1618.5 + W

W = 3231.5 J

now we know that at constant pressure the work done is given as

W = P\Delta V

3231.5 = P(V_f - V_i)

3231.5 = 5.5 \times 1.01 \times 10^5(V_f - 10.5 \times 10^{-3})

V_f = 16.3 \times 10^{-3} m^3

or we have

V_f = 16.3 Ltr

Which one of the following statements best illustrates implicit memory?
Temka [501]
I believe the answer is A. <span>At age 40, after 15 years, George got on his old bike and found he could still ride it without falling on his face.
Implicit memory is the type of memory that we've acquired in the past and often used automatically/subconsciously.
Other examples of implicit memory is when we could do a certain task that we're used to do even without paying any attention.</span>

A rotating space station is said to create "artificial gravity" - a loosely-defined term used for an acceleration that would be
FrozenT [24]

Answer:

\omega=0.31\frac{rad}{s}

Explanation:

The artificial gravity generated by the rotating space station is the same centripetal acceleration due to the rotational motion of the station, which is given by:

a_c=\frac{v^2}{r}(1)

Here, r is the radius and v is the tangential speed, which is given by:

v=\omega r(2)

Here \omega is the angular velocity, we replace (2) in (1):

a_c=\frac{(\omega r)^2}{r}\\\\a_c=\omega^2r

Recall that r=\frac{d}{2}=\frac{200m}{2}=100m.

Solving for \omega:

\omega=\sqrt{\frac{a_c}{r}}\\\omega=\sqrt{\frac{9.8\frac{m}{s^2}}{100m}}\\\omega=0.31\frac{rad}{s}

Particle A has very little mass in comparison to Particle B. Both particles are in the same atom. Which is the best conclusion a
ollegr [7]
Particle-A is an electron, racing around in a cloud that's far from the nucleus.

Particle-B is either a proton or a neutron, in the nucleus.

The big clue is where you said that particle-A has very little mass
compared to particle-B.  Protons and neutrons have almost identical
masses, but it's the same mass as more than 1,800 electrons !
