    B Can we use temperature differences for power generation?

    What I meant is collecting energy from air like 10 unit of 25°c air -> 9 unit of 20°c air + 1 unit of air which is hot enough to run the generator

    B Can we use temperature differences for power generation?

    Wouldn't it be wonderful if we can "collect" the thermal energy and turn it into electricity😂😂 Such a shame that we can't make this feasible (yet?) 😂😂

    B Can we use temperature differences for power generation?

    I remember that the definition of temperature is the average kinetic energy. Then how about if I keep shaking a box, wouldn't the kinetic energy of the box increase and thus the temperature of it increase? (neglecting the thermal energy gain from friction) Also, is it possible to use...

    Calculating Period of Transverse Wave from Photo: A or B?

    Homework Statement The problem is shown on the photo. And the actual answer is A. 0.5s, and I thought it would be B. 1.0s Homework EquationsThe Attempt at a Solution Here is my thought, The journey from A to B is just a half period, then the whole period would be 4s, as a result, the time it...
