Moving Charges

NIce!

Thanks, great questions

Please find some answers below:<br /> 1. Electric current is the movement of charged particles (electrons)<br /> 2. We are being asked to calculate charge<br /> Q = I x t<br /> No it doesn’t need rearranging<br /> Yes the units are correct<br /> Q = 1.5 x 90<br /> Q = 135 C<br /> 3. Calculate current<br /> Q = I x t<br /> Yes it needs rearranging<br /> I = Q/t<br /> Yes the units are correct<br /> I = 350/70<br /> I = 5A<br /> 4. How much charge?<br /> Q = I x t<br /> No it does not need rearranging<br /> No the units for time are not correct, they are in minutes and not seconds<br /> To convert 5 minutes to seconds: 5 x 60 = 300s<br /> Q = 2 x 300<br /> Q = 600C<br /> 5. How long will it take?<br /> Q = I x t<br /> Yes is needs rearranging<br /> t = Q/I<br /> Yes the units are correct<br /> t = 2000/2.5<br /> t = 800s<br /> 6. a) How long will it last?<br /> Q = I x t<br /> Yes it needs rearranging<br /> t = Q/I<br /> Yes the units are correct<br /> t = 1800/0.5<br /> t = 3600s<br /> b) How much charge?<br /> Q = I x t<br /> No it does not need rearranging<br /> No the units are not correct, time is in minutes and not seconds<br /> To convert 5 minutes to seconds, 5 x 60<br /> Q = 1.5 x 300<br /> Q = 450s<br /> 7. <br /> a) 768 is the anomalous result.<br /> b)Longalast: 952 Durablast: (The anomalous result should not be included when calculating the mean for Durablast) (888+900)/2 = 984<br /> Morelife: 908<br /> c) Longalast : 1095 Durablast : 1118 Morelife: 1090<br /> d) A bar cart for each battery showing the amount of charge for each battery<br />

I have made the necessary changes to the worksheet and look forward to using them with my year 11's. Thanks for sharing
