The correct option is D.
Destructive interference is said to occur when two waves superpose in such a way that they cancel each other out. The two waves are usually of equal frequency and opposite phase, the negative displacement of one wave collides with the positive displacement of the other wave, thus cancelling each other out.<span />

Answer:
Explanation:
Given
Distance between Pluto and sun is 39.1 times more than the distance between earth and sun
According to Kepler's Law
where k=constant
T=time period
R=Radius of orbit
Suppose is the radius of orbit of earth and sun
so Distance between Pluto and sun is
and is the time period corresponding to and R_2[/tex]
divide 1 and 2
Answer:
5) Friction.
Explanation:
The force that provides the necessary centripetal acceleration is the friction. The centripetal acceleration must be horizontal, directed to the center of the circular trajectory. Gravity and normal force are vertical, air resistance is against the speed of the car (not towards the center of the trajectory) and there is no tension in this example.
