PLEASE HELP ASAP!!! Analyze Your Data
1. Calculate the frequency of waves 4, 5, and 6.
Remember that frequency is the same as the
number of waves that pass in one second.
2. Calculate Use the equation v = f1 to find the
wavelength of waves 4, 5, and 6. Use the average
speed calculated in step 6 for the wave speed.
3. Identify the potential sources of error in this lab.

Conclude and Apply
1. Compare Were the three wave speeds that you
calculated in step 6 significantly different from
one another? Why or why not?
2. Explain why you would average the speeds of the
three different pulses to calculate the speed of the
waves on the spring.
3. Describe how the wavelength of the waves that
you created depends on the frequency of the
waves.

Trumpeter a holds a b-flat note on the trumpet for a long time. person c is running towards the trumpeter at a constant velocity. person b is running away from the trumpeter at the same rate. person d is standing still the whole time. which person hears a frequency that is lower than the b-flat?

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
