Step 5: Measure the Speed of the Toy Car on the Higher Track Calculate the change in time for each quarter of the track. Record the change in time in Table E of your Student Guide.

The change in time for the first quarter is seconds.

The change in time for the second quarter is seconds.

The change in time for the third quarter is seconds.

The change in time for the fourth quarter is seconds.

The step-down transformer gives a current of 10a at 24v if the primary voltage is 240v calculate the 1_primary current 2_the power input 3_the power output

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90
