A bird is flying at a constant speed of 8.0 m/s. The birds KE is 4.00x 10^3 what is its mass?

Work out sian speed for the first 30 minutes of her journey. give your answer in km/h.

Which atomic model was proposed as a result of j. j. thomson’s work?

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
