How Much Does Temperature Increase When Drilling Copper?

AI Thread Summary
The discussion focuses on calculating the temperature increase of a copper piece when drilled with a 40 W electric drill over 30 seconds. The user applies the formula Q = mcT, where Q represents heat energy, m is mass, and c is specific heat capacity. They calculate the energy produced by the drill as 1200 J and rearrange the formula to find the temperature change, resulting in a ΔT of 31.01 degrees Celsius. The calculations are confirmed as correct by another participant. The thread effectively demonstrates the application of thermal energy equations in practical scenarios.

[SOLVED] Find Change in Temperature

Homework Statement



An electric drill bores through a .100 kg piece of copper in 30 s. Find the increase in the temperature of the copper if the drill operates at 40 W. Assume that the drill does not increase in temperature.

Homework Equations



Q = mcT

The Attempt at a Solution



Can someone check to see if I'm doing this right?
I know the P = W/T so I would have to multiply T by Watts. I get 1200 J. I then rearrange Q = mcT to T = Q / mc. T = 31.01 degrees C.

Remember that is \Delta T the change in temperature. Your method looks ok to me.
 

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...
