Answer:
The change in internal energy is zero.
(a) is correct option
Explanation:
Given that,
Work done W = -400 J
The First law of thermodynamics is law conservation of energy
Law of conservation energy is defined the total amount of energy is constant in isolated system.
The energy can not be created and destroyed but the energy can be changed from one form to other form.
The First law of thermodynamics is given by
Where,
W = work done by the system or on the system
= Total internal energy
Q = heat
In isothermal process, the temperature is constant
The energy can not be change and the internal energy is the function of temperature.
So, The internal energy will be zero .
Hence, The change in internal energy is zero.
<span>So we want to know what does occur when light is refracted from a rough and unpolished surface. The correct answer is A. the original pattern of the light is distorted because rough and unpolished surfaces dissipate light in all directions so we cant get a clear image.</span>
Answer:
kinetic energy; total energy
Explanation:
Equation: PE+KE=TE
Hope this helps!
Answer:
The planes´s horizontal distance is DH = 13845 meters
Explanation:
We need to get the vector components because we already know the distance and the angle so using the trigonometric identity of Cos(Ф) we can get the horizontal component and if we get the component on x axle like 22000 (m)*Cos(51°) = x so we can find that x = 13845.05 meters
