Which statement correctly describes the movement of thermal energy according to the second law of thermodynamics? The natural te

ndency of systems is for heat to flow from a cooler object to a warmer one. The natural tendency of systems is to evenly distribute energy until the objects are the same temperature. The natural tendency of systems is for heat to flow continuously between objects of the same temperature.

Answer:

The correct answer is:

The natural tendency of systems is to evenly distribute energy until the objects are the same.

Explanation:

Thermal equilibrium

When ever two bodies differing in temperatures comes in contact with each other heat flow takes place from hotter body to cooler body in order to establish an equilibrium in which temperature of both the bodies becomes constant.

According to second law of thermodynamics:

When the energy of the system increases, matter moves more freely and change in entropy that is disorderliness of the system increases.

This increase in entropy is due to the energy possessed by the matter particles which has resulted in their motion or movement

With this increase in entropy of system, system will start interacting with its surroundings .And this interaction will results in evenly distribution of energy in its surroundings.

A sample of n2 gas occupies a volume of 746 ml at stp. What volume would n2 gas occupy at 155 ◦c at a pressure of 368 torr?
musickatia [10]

Answer:

2.41 L

Explanation:

We can solve the problem by using the ideal gas equation, which can be rewritten as:

\frac{p_1 V_1}{T_1}=\frac{p_2 V_2}{T_2}

where we have:

p_1 = 1.01\cdot 10^5 Pa (initial pressure is stp pressure)

V_1 = 746 mL = 0.746 L = 7.46\cdot 10^{-4}m^3 is the initial volume

T_1 = 0^{\circ}=273 K is the initial temperature (stp temperature)

p_2 = 368 torr = 4.9\cdot 10^4 Pa is the final pressure

V_2 = ? is the final volume

T=155^{\circ}=428 K is the final temperature

By substituting the numbers inside the formula and solving for V2, we find the final volume:

V_2 = \frac{p_1 V_1 T_2}{T_1 p_2}=\frac{(1.01\cdot 10^5 Pa)(7.46\cdot 10^{-4} m^3)(428 K)}{(273 K)(4.9\cdot 10^4 Pa)}=2.41\cdot 10^{-3} m^3

which corresponds to 2.41 L.

Julie drives 100 mi to Grandmother's house. On the way to Grandmother's, Julie drives half the distance at 44.0mph and half the
sashaice [31]

Answer:

52.47706 mph

54.5 mph

Explanation:

The average speed is given by

V_{av}=\dfrac{Distance}{Time}

V_{av}=\dfrac{100}{\dfrac{50}{44}+\dfrac{50}{65}}\\\Rightarrow V_{av}=52.47706\ mph

Julie's average speed on the way to Grandmother's house is 52.47706 mph

V_{av}=\dfrac{44+65}{2}\\\Rightarrow V_{av}=54.5\ mph

Average speed on the return trip is 54.5 mph

The figure shows five electric charges. Four charges with the magnitude of the charge 2.0 nC form a square with the size a = 4.0
bearhunter [10]

Considering the four electric charges forming a square with magnitude of charge of 2.0 nC on each. :

A) Magnitude of the force on the 5.5 nC charge in the middle of the figure = 3.48 * 10^-4 N

B) Direction of the force on the 5.5 nC charge in the middle of the figure = Leftward ( negative x -axis )

Using the given data :

size of square = 4 cm

magnitudes of four charges = 2.0 nC

<u> a) </u><u>magnitude</u><u> of the force on the center charge </u>

Electric force between two point charges = F = \frac{1}{4\pi *E_{o} } \frac{q1q2}{r^2} ----- ( 1 )

where ; \frac{1}{4\pi E_{o} } = 9 * 10^9 Nm^2/C^2

step 1 ; find r ( distance between charges )

r² = ( 2 )² + ( 2 )² = 8 cm²  

back to equation 1

F = 9 * 10⁹ * \frac{2 * 10^{-9} *  (5.5 * 10^{-9})  }{8*10^{-4} } =  1.23 * 10^-4  N

∴ magnitude of the force on the center charge ( Fnet )= 4F cos 45°

        = 4 * ( 1.23 * 10^-4 ) * \frac{1}{\sqrt{2} }  = 3.48 * 10^-4 N

b) The direction of the force at the center is along the negative x-axis ( leftward )

<em>Answer: </em>

1. The <em>"contour interval'</em> identifies the standard difference in elevation on a topography graph. It shows the difference in elevation of highest and lowest points on a topography map.   In topographic map every fifth contour line is drawn, wider than the contour lines, called as contour index.


2. Geologist usually study all the materials that make up the earth. He can focus on different rock samples from earth's surface. the geologist works to understand history of the planet where we live on, to predict the future by explaining current occurrences.


3. The difference between the top of the plateau and the lowest point in the area of 250 m measurement is called <em>elevation. </em><em>Elevation is the highest point in the area.</em>


<em>4. </em>Damage from earthquakes is determined by <em>"Ritcher scale"</em>. Seismic waves are the vibrations occurs from earthquakes that can travel through the earth. These vibrations can be detected by the Ritcher scale.
