Given the average power of the sun is 3.79x1024 watts, answer the following questions: 13. what is the average intensity of light at earth's position? 14. what would be the pressure on a solar sail due to the light of the sun if it's (a) fully reflective or (b) fully absorptive? 15. what would be the total force on the sail if its fully extended area was 4.4x10 mº? 16. what would be the acceleration of the sail and its payload if the sail has a surface mass density of 1.1 g/m2 and the payload is 95 kg? bonus) what would be the equation of the acceleration as a function of the distance from the sun?

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

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.
