Single pulley does not provide any mechanical advantage, it only changes the direction of force while an inclined plane provides mechanical advantage. This means the efforts required to life the same amount of load on an inclined plane is lesser than that by a single pulley. (Pulley provides mechanical advantage only if we use more than one pulley).Lesser the inclination more is mechanical advantage and lesser the effort. That means the correct answer should be 'D'

Of the three mediums, sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Sound waves need a medium to pass through. Liquid molecules are not packed as tightly as solids, and gases are very loosely packed. The spacing of the molecules enables sound to travel much faster through a solid than a liquid or a gas. Sound travels about four times faster and farther in water than it does in air. That means the right answer is Option D.i am the smartest guy in sofi have got once international rank 1in level 2
