Answer:
PART A: 412.98 nm
PART B: 524.92 nm
Explanation:
The equation below can be used for a diffraction grating of nth order image:
n*λ = d*sinθ
Therefore, for first order images, n = 1 and:
λ = d*sinθ.
The angle θ can be calculated as follow:
tan θ = 9.95 cm/15.0 cm = 0.663 and
θ = (0.663) = 33.56°
Thus: d =λ/sin θ = 461/sin 33.56° = 833.97 nm
PART A:
For a position of 8.55 cm:
tan θ = 8.55 cm/15.0 cm = 0.57 and
θ = (0.57) = 29.68°
Therefore:
λ =d*sin θ = 833.97*sin 29.68° = 412.98 nm
PART B:
For a position of 12.15 cm:
tan θ = 12.15 cm/15.0 cm = 0.81 and
θ = (0.81) = 39.01°
Therefore:
λ =d*sin θ = 833.97*sin 39.01° = 524.92 nm
Answer: aerodynamic force
Explanation:
The time-varying aerodynamic force causes the ball to move erratically. This motion is the source of the "dancing" knuckleball that confuses both batters and catchers alike.
Explanation:
According to law of conservation of energy, energy can neither be created nor it can be destroyed. It can only be transformed from one form to another.
Therefore, when pendulum is at highest point of its swing then it had only potential energy and zero kinetic energy. But when swing reaches at the bottom then potential energy converts into kinetic energy as height is zero.
Hence, potential energy = kinetic energy.
Thus, we can conclude that kinetic energy at the bottom of swing of pendulum is 359 J.
