Carnot Air Conditioner Question.

AI Thread Summary
A Carnot air conditioner operating between 20C indoors and 39C outdoors requires 130J of energy to remove 2000J of heat from the house. One participant calculated 121J, leading to confusion over the correct answer. The discussion also raises a question about the Coefficient of Performance (COP) of the air conditioner. The COP is a crucial metric for evaluating the efficiency of cooling systems. Understanding these calculations is essential for optimizing energy use in air conditioning.

Q:

A Carnot air conditioner operates between an indoor temp of 20C and an outdoor temp of 39C, how much ENERGY does it need to remove 2000 J of heat from the interior of the house?

A: 130J

i got 121J

O.o?

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging 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...
