Sean Andrew Logan 18 September 2007 PHY110 (Lab) Tue. 11am Q1. A little over two US teaspoons equals ten millilitres. Q2. There are about five millilitres in one US teaspoon. Q3. There would be twenty teaspoons in a litre because 10 10ml=1liter so 10 2ts=20ts or 1litre. Q4. To make one quart, one would need .95 litres. Q5. (A) A kilo feels like it weighs roughly double that of a pound. (B) A kilo is 2.21pounds. (C) Yes, I think it was very good estimate. Q6. (A) My desk is four feet eleven inches or… (B) One metre fifty centimetres. (C) One metre equals a little more than three and a quarter feet. (D) My conversion factor is .3of a foot (about three inches) off. Q7. In both our trials the average speed of the balls increased as height did. Q8. (A) It would continue to increase until it reached a point when it levelled out because of the air resistance. (B) Yes, our data does support this. Q9. I don’t think our data is thorough enough to come to a conclusion about mass and speed, but if I had to guess I would say more mass equals more speed.

Unformatted text preview: Q10. The force acting on the ball is gravitational force. Ball 1: .057kg 9.8m/s 2 =.55986N Ball 2: .0094kg 9.8m/s 2 =.09212N Q11. On the moon they would be: 1 Sean Andrew Logan 18 September 2007 PHY110 (Lab) Tue. 11am Ball 1: .057kg(1/6 9.8m/s 2 )=.0931N Ball 2: .0094kg(1/6 9.8m/s 2 )= 0.015353N Q12. Our fist object had a density of 2.7 g/cm 3 so its Aluminium. And our second one had a density of 8.9 so it was copper. Q13. Mass times density would yield volume. Mass Density=Volume Q14. The voltage generated is decreased as the spacing is increased. Q15. I would think not because they would be farther apart. Q16. There probably not be lemon powered cars in the future (they would probably be lemons! Lol) but the theory behind it, acid giving power, is used with stronger acid in batteries, so I guess it would be theoretically to have a lemon powered car, but it would not be economical. 2...
