Answer:
1.33
Explanation:
Using the formula for destructive interference since the two reflected ray light waves from eyeglass should be made to cancel each other ( destructive interference) and also refractive index of air less than the refractive index of the film and both are less than the refractive index of the glass meaning the both reflected rays from the air and film will experience a phase change
n film = ( m + 0.5) ( λ / 2t)
since 2 t = ( m + 0.5) ( λ / n film)
where m is an integer, λ is wavelength, and t is thickness and n film is the refractive index of film
for effectiveness m = 0
n film = ( 0.5) ( 480 ÷ (2 × 90 ) ) = 1.33
Answer:
Explanation:
Given:
As we know that
Force=Mass * Acceleration
Putting the value of mass and Acceleration we get ,
Therefore Net force is :
I believe the answer is A.
Answer:
What is the magnitude of the player 's displacement? A baseball "diamond" is a square, each side of length 27.4 m, with home plate and if each length of the base is 27.4 m, and the baseball player ran to third base,Then, the baseball player is 27.4 feet away from home plate (where he started)below the horizontal.
