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.

Just incase you cannot read it, it says: figure one shows that the demand for electricity in a house varies during a summer day. air conditioning is used in the house and cheap electricity is available at night for washing clothes and other appliances. suggest reasons for demand at these times: 21: 00-01: 00 07: 00-9: 00 18: 00-20: 00
