PHY 101: Intro to Physics - Lab 2 ACTUAL UPDATED QUESTIONS AND CORRECT
ANSWERS
In the experiment you used objects with masses that 40 grams
were not necessarily known. Assume that it is determined
that the mass of an object that produces a deformation of
size 3, is 120 grams. What is the mass of an object that
would produce 1 unit of deformation?
20 grams,
25 grams,
30 grams,
35 grams,
40 grams,
45 grams,
50 grams,
60 grams,
, In the experiment you used objects with masses that The masses are equal. Objects of equal mass have the same weight, which is the
were not necessarily known. Assume that for a certain force producing the deformation
object you observed a deformation of size 3. Next, you
remove that object and hang a second, different object,
made of different materials, and observe that the
deformation is the same. What can you say about the
mass of the second object compared to the first? Select,
the correct answer and the best argument for it.
There is no relation between the masses since they are
not made of the same materials,
There is no relation between the masses, but they must
have the same density to be able to extend the bands
equally,
The masses are equal. Objects of equal mass have the
same weight, which is the force producing the
deformation,
The masses are equal. When the deformations are the
same, this indicates the densities of the materials are the
same,
There is no relation between the masses,
Their weight is the same as shown by the equal
deformation, but weight is not directly related to mass,
The masses are equal. The deformation is the same and
this indicates that the inertia of the objects is also equal,
When you stretch a rubber band with a pair of fingers, Two forces. One pulling at each end of the band
what is the number of forces that should be used to
described the action of your hand on the rubber band?
Select the number and the associated explanation.
Ignore the weight of the band.
One force. The band is interacting with just one object,
your hand,
One force. The band is subject only to the net force on it,
Two forces. One pulling at each end of the band,
Two forces. One pulling and one pushing, to obtain
equilibrium,
Two or more forces. At least two are necessary but more
are possible, depending on the relative orientation of the
band,
Two or more forces. The number is not only determined
by the interaction with the hand but must also include
other details of the system,
