PLS HELP NOW The members of a family observed that their water meter was showing unusually high water use. They thought of two methods to solve this problem.

Method 1: Run the dishwasher and clothes washer only when they are half full.
Method 2: Check all the faucets and pipes in the house to mend leaks.

Which of these statements is most likely correct about the two methods of water conservation?

Method 1 is ineffective.
Method 2 is not practical.
Method 2 is difficult to implement.
Method1 is not healthy for humans.

Taylor's experiment: 1. accurately measured the speed of light 2. locked together the phases of two light sources so that the interference pattern would not shift 3. showed that man's reaction time was much slower than the speed of light 4. showed that individual photons have wave characteristics

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.
