Physics Assignment #
1:
Representations, Units and Dimensions
Mon 11 Sept. 2000 - finish by Mon 18 Sept. 2000
- 1.
- Web Surveys:
Complete and submit the two surveys -
Learning Styles
and Physics Survey -
posted on our Web site.
- 2.
- Primes:
Discuss the circumstances under which the integer 10
can be a prime
(i.e. evenly divisible by
no other integers except 1 and itself).
- 3.
- The Art of Estimation:
- (a)
- [easy]
Without consulting any books, notes or other people,
estimate the surface area of the Earth.
Don't forget to include your quantitative uncertainty.
In Physics this is conventionally expressed with a
sign
in the form
.
- (b)
- [medium]
Estimate the volume of the Science 1
lecture room in units of ns3.
- (c)
- [hard]
Remembering that the Earth's gravitation drops off as
1/r2 (where r is the distance from the centre of the Earth),
estimate how long it would take a rock
to fall to the Earth's surface starting from rest
at an initial distance of
ri = 80,000 km.
Again, don't forget to include your uncertainty.
(For this one, consult all you want!)
. . . and

(for Canada)
& 37
E.g.
m2.
The answer is in the back of the book;
don't peek until you try it!.
