Acceleration is the slope of a velocity-time graph. Change in position is the area under the graph from the start time to the end time. - Remember to add this to the initial position Until you do calculus, you pretty much need to learn that by heart. (If you have some calculus, the above...

1. I would put the error in your first case as +/-0.5, then +/-5 and +/-50. I don't think notes are always consistent about that, though. Otherwise, you're correct. 2. This is most applicable when you have varying numbers of sig figs. eg: 5.3*2.13546723435 + 6*7.93548 = 11.3179763 + 47.61288...

My physics lecturer has never said that his job more often than not involves being called in, checking the basic technical stuff, analysing the problem and discovering that the issue is a fraudulent employee/improperly trained personnel/something very non-technical. My engineering lecturer most...

Ohhh, I get it now. Thanks!

Homework Statement A uniform rope of length L hangs freely from the ceiling. Show that the time for a transverse wave to travel the length of the rope is t0 = 2\sqrt{L/g}. Homework Equations v = \sqrt{\tau/\mu}. (Where \tau is the tension and \mu the linear density of the rope.)...

You can solve it using the same general technique, but you need to calculate the tension for each string separately. You should be able to make a Newton II (Fnet=mblockasystem) equation for each block. Then solve the equations for T1 (or whichever tensions you need) and asystem.

I'm three quarters of the way through first year (electronic) engineering, but seriously considering switching to a physics/maths double major. My academic advisor is pretty focused on preventing engineering 'dropouts' and seems to think that if, like me, you're getting straight firsts, you'd...
