D. 5.098 x 106 is the correct answer when reduced to the proper notation.
Answer: is C
Expiation: you can find the answer on quizlet and it’s diverging mirror so the answer is C
Impulse = change in momentum
J = mΔv = (65.1 kg)(1.82 m/s) = 118.5 kg-m/s
the floor exerts the normal force, which is equal to the player's weight
N = W = mg = (65.1 kg)(9.8 m/s²)
Impulse = average force * time applied
118.5 kg-m/s = F (0.450 s)
Answer:
The diameter of the camera aperture must be greater than or equal to 1.49m
Explanation:
Let the distance separating two objects, x = 6.0 cm = 0.06 m
The distance between the observer and the two objects, d = 160 km = 160000 m
Let ∅ = minimum angular separation between the two objects that the satellite can resolve
tan( ∅) = x/d
Since there is minimum angular separation, tan( ∅) ≈∅
∅ = x/d
∅ = 0.06/160000
∅ = 3.75 * 10⁻⁷rad
For the satellite to be able to resolve the objects,
D ≥ 1.22λ/∅
λ = 560 nm = 560 * 10⁻⁹
D ≥ 1.22 * (560 * 10⁻⁹)/(3.75 * 10⁻⁷)
D ≥ 149.33 * 10⁻² m
D ≥ 1.49 m
