I am taking an educated guess that he has life insurance
Answer:
0.0003 m = 0.3 mm
Explanation:
For constructive interference in the Young's experiment.
The position of the mth fringe from the central fringe is given by
y = L(mλ/d)
λ = wavelength = 720 nm = 720 × 10⁻⁹ m
L = distance between slits and screen respectively = 1.0 m
d = separation of slits = 0.68 mm = 0.68 × 10⁻³ m
m = 2
y = 1(2 × 720 × 10⁻⁹/(0.68 × 10⁻³) = 0.00212 m = 2.12 mm
For the 620 nm light,
y = 1(2 × 620 × 10⁻⁹/(0.68 × 10⁻³) = 0.00182 m = 1.82 mm
Distance apart = 2.12 - 1.82 = 0.3 mm = 0.0003 m
The answer is "heat transfer."
Answer:
A
Explanation:
Momentum is mass times velocity.
A. 275 kg × 0.55 m/s = 151.25 kgm/s
B. 2.7 kg × 7.5 m/s = 20.25 kgm/s
C. 91 kg × 1.4 m/s = 127.4 kgm/s
D. 1.8 kg × 6.7 m/s = 12.06 kgm/s
So A has the greatest momentum.
