Answer:
63.8 kJ
Explanation:
The net work output per cycle is the difference in heat input and heat output. The heat input and heat output are expressed as a function of volume ratios, while volume is expressed as a function of pressure and pressure as a function of temperature.
R = 287 J/kg.K, k = 1.4
Hence the net work input (W) is given as:
Since you already give the equation, we simply identify the given.
With do = 50.0cm and f = 25.0cm, so
di = (50*25)/(50-25) = 50 cm
The answer is A.
Answer:
B
Explanation:
You would have rain. You would have clouds, precipitation, and strong winds.
Answer:
(C) increase the distance between the slits in the diffraction grating
Explanation:
This light always form constructive interference, the difference in distance is given λn.
where;
λ is the wavelength
n is the nth maxima
At center fringe, n = 0; the difference is 0
for the first maximum, n= 1, the difference is λ
for second maximum, n = 2, the difference is 2λ
for third maximum, n = 3, the difference is 3λ
From the above illustrations, the wavelength is constant, but the distances between the slits increases, resulting in a higher difference.
Therefore, Option C is the correct answer: increase the distance between the slits in the diffraction grating
Answer:
Informal education is important because it can help individual to learn how to react and control situations.
It help individual to improve on its existing knowledge, new skills or ideas. This kind of education can happen any where and it can add values to the learner.
