AI Thread Summary
Signal and time displays in everyday devices include televisions, which receive signals over time to produce images, and thermostats that display ambient temperature based on received signals. Ovens also fit this category as they register and display temperature readings. Additionally, any device that can be powered on or off with a switch completes a circuit, highlighting the time aspect of signal processing. Clarification on the specific types of signals and their display mechanisms would enhance understanding of these devices. Overall, the discussion emphasizes the various ways devices interpret and display signals over time.

Question:
What signal (voltage or otherwise) vs time displays do you have in your house?

Answer?
I am a little confused as to what exactly this question is asking. My initial suspicions say that a TV because they receive a signal over time and display that as picture on the screen. Also I think that a thermostat would receive a signal of the ambient temperature and display that the temperature and by similar reasoning a oven. And lastly would any device to which the power can be turned on and off with a switch, by the rational that they complete a circuit and it takes time to charge the circuit

Any advice on the correct rational for the solutions are greatly appreciated!

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'

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...
