Answer:

The correct option is (E) "Second law of thermodynamics"

Explanation:

The Second law of Thermodynamics states that<em> In the absence of reversibility of the processes which an isolated system undergoes, the total entropy or "disorder" of a system increases</em>.

  • An Energy transformation (Process which the system undergoes) that may be Work done on the system or heat flow to or from the system (e.g. Piston cylinder assembly bearing a gas) being irreversible processes occurring between the system and its boundary will always increase the disorder of the system. Increasing its Entropy or Disorder.

Answer:

(E) Second law of thermodynamics

Explanation:

The second law of thermodynamics can be understood according to Clausius' words: In an isolated system, no process can occur if a decrease in the total entropy of the system is associated with it. These processes are associated with energy transformations, in which a variable is introduced, called entropy that indicates the notion of disorder. Therefore, in any isolated process, the disorder can only grow.

How many miles between a point 60 ° north latitude and 30 ° west longitude and a point 60 ° north latitude and 60 ° east longitu
kramer

-- We're pretty sure that this question is based on an assumption of EARTH, so we know that we're dealing with a sphere of roughly 3.950 miles radius.

-- The distance on the sphere between 30° west and 60° east is 90° of longitude.  That's 1/4 of the total circumference of the circle.  

-- BUT ..... Way up here at 60° N latitude, the circle is not as big as the equator.  It's radius/diameter/circumference is only cos(60°) = 0.5 of the Earth's total.

-- So the length of our quarter-circle arc is about

(1/4) x (2 · π · 3,950 miles) x (0.5) =

(1/4) x (3,950 π miles) =

988 π miles = 3,104 miles

A car moves with a speed of 72 km/h for 15 minutes and then with a speed of 80 km/h for the next 12 minutes. The total distance
sukhopar [10]

Answer:

The total distance covered by the car is 3,810.08 m

Explanation:

Given;

initial speed of the car, u = 72 km/hr = 20 m/s

initial time, t₁ = 15 minutes = 900 s

final speed of the car, v = 80 km/hr = 22.22 m/s

final time, t₂ = 12 minutes = 720 s

The acceleration of the car is given as;

a = \frac{v-u}{t_2 -t_1} \\\\a = \frac{22.22-20}{900-720}\\\\a = 0.0123 \ m/s^2

The total distance covered by the car is given as;

v² = u² + 2as

where;

s is the total distance covered by the car

22.22² = 20² + 2(0.0123)s

22.22²  - 20² = 2(0.0123)s

93.728 = 0.0246s

s = 93.728 / 0.0246

s = 3,810.08 m

Therefore, the total distance covered by the car is 3,810.08 m

. A magnetic field has a magnitude of 0.078 T and is uniform over a circular surface whose radius is 0.10 m. The field is orient
Dmitriy789 [7]

Answer:

The magnetic flux through surface is 2.22 \times 10^{-3} Wb

Explanation:

Given :

Magnitude of magnetic field B = 0.078 T

Radius of circle r = 0.10 m

Angle between field and surface normal \theta = 25°

From the formula of flux,

\phi = B.A

\phi = BA\cos \theta

Where \theta = angle between magnetic field line and surface normal, A = area of circular surface.

A = \pi r^{2}

A = 3.14 \times (0.10) ^{2}

A = 0.0314 m^{2}

Magnetic flux is given by,

\phi = 0.078 \times 0.0314 \times \cos 25

\phi = 2.22 \times 10^{-3} Wb

Therefore, the magnetic flux through surface is 2.22 \times 10^{-3} Wb
