Explanation:
The given data is as follows.
= 400 K, = 500 K,
= 25 kJ = 25000 J (as 1 kJ = 1000 J)
Now, we will calculate the change in entropy as follows.
Putting the given values into the above formula as follows.
=
= 250 J/K
Hence, we can conclude that change in entropy is 250 J/K.
The acceleration of the object which moves from an initial step to a full halt given the distance traveled can be calculated through the equation,
d = v² / 2a
where d is distance, v is the velocity, and a is acceleration
Substituting the known values,
180 = (22.2 m/s)² / 2(a)
The value of a is equal to 1.369 m/s²
The force needed for the object to be stopped is equal to the product of the mass and the acceleration.
F = (1300 kg)(1.369 m/s²)
F = 1779.7 N
Bohrs atomic model only explains the atomic structure in which electrons travel around the nucleus in well-defined orbits determined by quantum conditions. A transition from a higher orbit to a lower orbit will release quantized energies of light, which would explain the light spectrum emitted by an element.
I think the correct answer from the choices listed above is option B. If asked to describe a wave, you could say waves are the continuous transmission of energy from one location to the next. <span>In physics, a </span>wave<span> is an oscillation accompanied by a transfer of energy that travels through a medium. Hope this helps.</span>
