Calculate the first and second velocities of the car with three washers attached to the pulley, using the formulas v1 = 0.25 m / t1, and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. Record these velocities, to two decimal places, in Table E.

The plum pudding model of the atom states that ?

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.
