a student suspends an object from a spring scale. a spring scale measures the weight of an object. the student records the weight. the student then submerges the object in water and observes that the spring shows a smaller weight than when the object was out of the water. the student then submerges the object in motor oil, vegetable oil, milk, and gasoline and observes the reading on the scale.

the independent variable in this experiment is the:
the weight read on the spring scale
the type of liquid in which the object was submerged
the size of the object
the amount of liquid in which the object was submerged

You will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. (refer to the walk-through video to locate the online lab within the online textbook).

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?

An charge with mass m and charge q is emitted from the origin, (x, y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
