Answer:
width of the slit = a = 0.0935 mm
Explanation:
width of central maximum for single slit diffraction is:
----- (1)
Distance between source and screen = L = 5.5 m
Width of bright band = w = 8 cm
= 0.08 m
λ = 680 nm
Width of the slit = a = ?
Arranging (1) for a
a = 0.0935 mm
1. The problem statement, all variables and given/known data A person jumps from the roof of a house 3.4 meters high. When he strikes the ground below, he bends his knees so that his torso decelerates over an approximate distance of 0.70 meters. If the mass of his torso (excluding legs) is 41 kg. A. Find his velocity just before his feet strike the ground. B. Find the average force exerted on his torso by his legs during deceleration. 2. Relevant equations I can't even seem to figure that part out. Help please? 3. The attempt at a solution I don't know how to start this at all
Answer:
Acceleration
Explanation:
acceleration because it has magnitude but no direction
