Experiment: Car 1 will roll down the ramp and exert a force on car 2. The force experienced by car 2 is measured indirectly using (the distance it travels? or its speed?)
. If the force increases, car 2 will travel (?slower ? Farther?)
. The independent variable, or what’s being manipulated in the experiment, is (? the starting height of car 1 or The type of bumper attached to car ?)
. The dependent variable, or what’s responding, is (?The distance car 2 travels or the speed of car 1?)
. The height and starting position on the ramp are constants in this experiment.

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

What are the theoretical properties of a gas at a temperature of 0 kelvin?

A3.9 g aluminum foil ball with a charge of +4.1×10−9 c is suspended on a string in a uniform horizontal e⃗ field. the string deviates to the right and makes an angle of 30∘ with the vertical. part a part complete what information about the e⃗ field can you determine for this situation? what information about the field can you determine for this situation? only the magnitude of e⃗ only the direction of e⃗ both the magnitude and the direction of e⃗ none of the above previous answers correct part b determine the magnitude of the electric field. express your answer with the appropriate units. e e = nothing nothing request answer part c determine the direction of the electric field. determine the direction of the electric field. to the right to the left away from you toward you
