Calculate the acceleration of the car for each set of conditions using the formula a = (v2 – v1) / (t2 – t1) where v2 and v1 are the first and second velocities and t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. acceleration is reported in m/s2. record these accelerations, to two decimal places, in table e. the acceleration for the car with one washer is m/s2. the acceleration for the car with two washers is m/s2. the acceleration for the car with three washers is m/s2. the acceleration for the car with four washers is m/s2.

Act has a 1200: 5 or 240: 1 turns ratio. it is short circuited. what is the maximum current at 1200a primary if we put a 100ohm resistor across the secondary end of the ct. use it as current source circuit.

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.
