Tutorial 1: Physical Quantities
1.
The mass of the planet Saturn is 5.64 x10
26
kg and its radius is 6.00 x 10
7
m.
a)
Calculate its density.
b)
If this planet were placed in a large enough ocean of water, would it float?
Explain.
2.
The planet Jupiter has an average radius 10.95 times that of the average radius of the
Earth and a mass 317.4 times that of the Earth. Calculate the ratio of Jupiter’s mass
density to the mass density of the Earth.
3.
Show that the equation x = vt + ½ at
2
is dimensionally correct , where x is a
coordinate and has units of length, v is speed, a is acceleration, and t is time.
4.
The square of the speed of an object undergoing a uniform acceleration, a is some
function of a and the displacement , s according to the expression v
2
= k a
m
s
n
,
where k is a dimensionless constant. Show that this equation is dimensionally correct
only if m = n = 1.
5.
The period T of a simple pendulum is measured in time units and is
T = 2
π
l
g
/
where
l
is the length of the pendulum and
g
is the freefall acceleration in units of
length divided by the square of time. Show that this equation is dimensionally correct.
