Can Two Batteries Power a Lunar Roving Vehicle Without Exceeding 9 Volts?

AI Thread Summary
Two batteries can power a lunar roving vehicle without exceeding 9 volts if they are connected in parallel rather than in series. When connected in parallel, the voltage remains at 9 volts, while the capacity increases. This configuration allows for separate power distribution to components like the front wheels. If the batteries were connected in series, the voltage would double to 18 volts, which is not permissible in this design. Therefore, the teacher's assertion about maintaining the voltage at 9 volts is correct.

I must design a lunar roving vehicle. One of the criteria is that the electric power cannot exceed 9 volts. My teacher said that is I have 2 batteries powering the front wheels separately then the power remains at 9 volts and not at 18 volts. Is this true?

Thanks!

Unless the batteries are connected in series, it is true.
 
Great thanks!
 

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...
