a) If N doubles N would decrease in size, or in other words, get smaller.
b) If N quadruples, N would decrease even more in size than if N were doubled
a) The standard deviation of the mean of the heights
a) If you apply Newtons 2nd law for the hanging mass, you get the net force
equation to be: Fnet =mh gT .
b) In order to relate torque on the pulley to the tension, you get the expression:
=R p T .
c) The expression for the torqu
a) We use springs in our daily life when pushing open a ballpoint pen, within
our mattresses, in a non-digital scale, and in a pinball machine.
b) The function of the spring in the projectile launcher from Activity 3 was to
After converting the velocity, 150 km/h, into meters/second I got 42 m/s for the
velocity in the direction of north. So I then multiplied the velocity by the mass, which is
1010 kg, to get the momentum of the car. The momentum of
The best way to increase the range of the ball would be to change the angle that at which
you release the ball, different angles would produce different ranges. Another way could be to
apply a harder force to the ball when being thrown.
a) In each plot, X is considered the independent variable.
b) The plots that show the best precision is graph b since precision is in the plot
with the points closest to each other.
c) The plots that show the best accuracy is grap
The wave in the positive x direction can be represented by:
y ( x , t ) =A sin (kxt) . The wave in the negative x direction can be represented by
y ( x , t ) =A sin ( kx+ t ) . So, the total of the waves can be represented by
a) You create a scatter-plot using Excel by first making sure you have all your data
imported. Once you have that, you then highlight both your X-values and Y-values
and select on the create a scatter plot option. You then make sur
In order for a physicist to recreate an experiment, a mini report must contain the
portion of the introduction that explains the model, how we derived the model, and the
limitations of that model. It should also contain the enti
Question 2.2 and 2.4:
1. You create a formula in Excel by first clicking on a box on the excel sheet.
Then, you go up to the top of Excel where it says fx and click on the empty
box right next to it. You then enter a equal sign and then can enter data and
a) The length of the wrench would be the lever arm in this scenario.
b) Since torque is expressed as =rF sin n^ , where is the angle between the
length of the lever arm r and the force applied F. Because of this, the torque is
maximum when i
