An experiment is performed in which a force is applied to two objects (A and B) and the resulting acceleration is measured. The graph below summarizes the results. Answer the following questions:

a. What is the relationship between force and acceleration?

b. What are the units for the slope of the line? Show you work below:
acceleration (m/s2)
Force (N)

c. Using the line equation (y = mx +b), derive a general equation that describes the relationship between force and
acceleration.

d. What does the equation you derived above tell you about the relationship between mass and acceleration?

You can decrease the resistance of a length of wire by

By what primary heat transfer mechanism does the sun warm the earth?

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
