Answer: Change in momentum=9.4kgm/s
Impulse=9.4kgm/s
Explanation:
Change in momentum=5.1-(-4.3)=5.1+4.3=9.4kgm/s
Impulse=Change in momentum
There impulse=9.4kgm/s
Answer:
Y = 3.87 x 10⁻³ m = 3.87 mm
Explanation:
This problem can be solved by using Young's double-slit experiment formula:

where,
Y = fringe spacing = ?
L = slit to screen distance = 2 m
λ = wavelength of light = 580 nm = 5.8 x 10⁻⁷ m
d = slit width = 0.3 mm = 3 x 10⁻⁴ m
Therefore,

<u>Y = 3.87 x 10⁻³ m = 3.87 mm</u>
