1. A space probe is launched vertically into space. It launches from rest and accelerates at a rate of 29 m/s2. How many seconds before the probe reaches the speed required to get into orbit, 7,850 m/s? (round to the nearest tenth)

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
