AI Thread Summary

To determine the number of excess or deficit electrons in a ping-pong ball with a charge of 3.2x10^-5C, the calculation involves dividing the charge by the fundamental charge of an electron (1.6x10^-19C). The result of this division yields approximately 2.0x10^14 electrons. The terms "too many" or "too few" refer to whether the ball has an excess or deficit of electrons compared to a neutral state. A positive charge indicates the ball has too few electrons. The final calculation confirms the number of electrons related to the given charge.

Homework Statement

If a ping-pong ball has a charge of 3.2x10-5C, how many too many or to few electrons does it have

Homework Equations

# of electrons=charge/fundamental charge

The Attempt at a Solution

3.2X10-5C/1.6X10-19=

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
