Arocket carrying a satellite is accelerating straight up from the earth's surface. at 1.15 s after liftoff, the rocket clears the top of its launch platform, 70 m above the ground. after an additional 4.70 s, it is 1.15 km above the ground. part a
calculate the magnitude of the average velocity of the rocket for the 4.70 s part of its flight.
express your answer in meters per second. part b
calculate the magnitude of the average velocity of the rocket the first 5.85 s of its flight.
express your answer in meters per second.

What are similarities and differences of reflection, refraction, diffraction and absorption?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
