Kepler-62e is a planet similar in size to the earth with an orbital period of 122 days. the star it orbits has a mass of 1.4 x 1030 kg. convert the period to hours and use newton's version of kepler's 3rd law to calculate the semimajor axis of this planet's orbit. your answer will not match any of these choices, instead choose the answer that is closest to your calculated value.

Two polarizers are oriented at 24.0∘ to one another. light polarized at a 12.0-degree angle to each polarizer passes through both. what is the transmitted intensity (%)?

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
