A mason worker throws the bricks to a height of 10m, at which the bricks reach with a velocity of 6m/s. The percentage of energy he is wasting is nearly (g = 10<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>m</mi><msup><mi>s</mi><mrow><mo>-</mo><mn>2</mn></mrow></msup></math>)

In a double slit experiment, the separation between the slits is d and distance of the screen from slits is D.

In Young’s double–slit experiment, the slits are 0.5 mm apart and the interference is observed on a screen at a distance of 100 cm from the slits. It is found that the ninth bright fringe is at a distance of 7.5 mm from the second dark fringe from the center of the fringe pattern. The wavelength of the light used is
