Answer:
C .25 grams
Explanation:
After each half life, the mass is reduced by half.
2/2 = 1
1/2 = 0.5
0.5/2 = 0.25
We need to draw a coordinates. the east and south should be the north vector for horizontal line 50 KM in distance is zero. the south is a negative. the south east and north west we should draw the 45 degrees angle in the approprate quadrant and then use the 1-1-sqrt(2) have a relationship in 45-45-90 triangles to resolve the N/S, E/W components.
hope this help
Answer:
7.8 mm
Explanation:
Wavelength = λ = 710 nm = 710×10⁻⁹ m
Distance between light sources = L = 9 m
Diameter of pinhole = d = 1 mm = 1×10⁻³ m
Rayleigh Criterion
Distance between difraction pattern is 7.8 mm.
