Which best explains who is correct?
Lexy is correct because angle R is between the incident wave, n = 0, and a diffracted wave.
Lexy is correct because angle R includes the diffracted wave at n = 1.
Jin is correct because angle S is measured from the barrier and includes n = 2, the wave that has the most diffraction.
Jin is correct because angle S is between the dimmest order bands, n = 1 and n = 2.

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

electrical power

talk back to him about the sport and show him your expertise or leave the room

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
