How is the weight of an object in a spaceship near the moon related to the distance that the spaceship is from the moon? a) there is is no gravity on the moon and therefore they are not related. b) as the distance to the moon decreases, the weight of the spaceship would increase. c) as the distance to the moon increases, the weight of the spaceship would increase. d) the gravitational pull of the moon is constant and therefore the weight would be a constant.

Scientists use laser range-finding to measure the distance to the moon with great accuracy. a brief laser pulse is fired at the moon, then the time interval is measured until the "echo" is seen by a telescope. a laser beam spreads out as it travels because it diffracts through a circular exit as it leaves the laser. in order for the reflected light to be bright enough to detect, the laser spot on the moon must be no more than 1.0 km in diameter. staying within this diameter is accomplished by using a special large-diameter laser. part a if λ = 540nm , what is the minimum diameter of the circular opening from which the laser beam emerges? the earth-moon distance is 384,000 km. express your answer to two significant figures and include the appropriate units.
