Answer:Half the wavelength
Explanation: Destructive Interencce is a type of wave superimposition which involves opposing waves, in this case the Trouph of one wave aligns with the crest of the opposing wave. In this case the smallest distance for the maximum destructive wave to take place is have the wavelength,if the wavelength is one lambda the smallest wavelength for the maximum destructive wave to occur is half the wavelength.
Answer:
Explanation:
From the question, we can see that the elevator is at a constant speed, invariably, acceleration is zero. And thus, there is no external force acting in the man, asides from force of gravitation acting on the man between those 5s. Now, we solve the question using newton's second law of motion.
The second law of motion states that, "the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object."
Summation Fy = ma(y)
F(n) - F(g) = 0
F(n) - mg = 0
F(n) = mg
F(n) = 77*9.81
F(n) = 755.37N
Answer:
63.78%
Explanation:
The equation that relates the angle of the polarization and the intensity of ligth transmitted is I=Io*cos²(x), where I is the intensity of the incident light, Io is the intensity of the transmitted light, and x is the angle of polarization. The fraction of incident light will be I/Io, so the answer in given by cos²(37) = 0.6378
