frez [133]

Answer:

= 9.8°

Explanation:

Width of one slit (a₁ ) = 1 / 1000 mm=0.001 mm = 10⁻⁶ m.

width of one slit in case 2 (a₂ ) = 1/500 =2 x 10⁻⁶ m

angular position of fringe, Sinθ  = n λ /a

n is order of fringe , λ is wave length of light and a  is slit aperture

So Sinθ  ∝ 1 / a

Sin θ₁ /Sin θ₂ = a₂/a₁ ;

Sin20°/sinθ₂ = 2 / 1

sinθ₂ = Sin 20° / 2 = .342/2 = .171

θ₂ = 9.8 °

If a car with mass 750 kg is lifted to a height of 2.3 m how much gravitational potential energy is added to the car
Jlenok [28]

I found: 16,905J

Explanation:

The Gravitational Potential Energy will depend on the work done against gravity (weight, W=mg) to lift it at height h or:

U = mgh =750 * 9.8 *2.3 =16,905J
