Energy transfer from cool part to hot part(q38)

AI Thread Summary
Refrigerators operate by transferring heat from the cooler interior to the warmer exterior, contrary to the natural flow of heat from hot to cold. This process involves removing heat from the food placed inside and expelling it outside, effectively cooling the interior. The discussion highlights confusion regarding the mechanism, emphasizing that while heat typically moves from hot to cold, refrigerators use energy to reverse this flow. The correct answer to the posed question is identified as option b, referring to the refrigerator's function. Understanding this principle clarifies how refrigerators maintain a cool environment for food storage.

the answer is c.

Can anybody kindly explain how this is achieve by refrigerator?
Because according for what I study so far , the energy is transfer from hot part to cool part...

you said c, but the answer refrigerator is answer b.

Refrigerators remove heat from the inside of it and pump it to the outside of it, the inside is usually cooler, so when you put your leftovers in it, the fridge pumps the heat from the food out of the 'cool' part (the inside of it) and takes it to the outside of it (the warm part).
 
Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
