When two waves interact with their crests and troughs in alignment is called constructive interference. If two waves of the same wavelength occupy the same space in such a way that their crests and troughs align, the wave they produce will have an amplitude greater than that possessed by either wave initially. This is known as constructive interference. The more closely the waves are in phase—that is, perfectly aligned—the more constructive the interference.
Answer:
Option (C)
Explanation:
Flash flood refers to the sudden flood that occurs in a particular area due to the heavy and excessive amount of rainfall, often accompanied by thunderstorms within a few hours. It releases a huge amount of water due to the failure of natural levee as well dam. They are very devastating. During flash flood, the water exerts a massive force which can make vehicles float over water. The <u>six inches of water</u> that flows over an area has the capacity to lift the tyres of small vehicles and carry hem further away.
Thus, the correct answer is option (C).
The vibrations created by noise can be converted to electrical energy through the principle of magnetic Induction, for example by using transducer.
Answer:
vf = 50 m/s
Explanation:
The equation for this kinematic problem is:
vf = vi + at
We are given:
a = 10m/s^2
vi = 0m/s
t = 5 sec
vf = ?
Solve for final velocity:
vf = 0 + 10(5)
vf = 50 m/s
Answer:
Explanation:
Given:
Acceleration, a = -2.4 m/s^2
Acceleration due to gravity, g = 9.8 m/s^2
Sum of forces = 0
Fr + F = 0
Fr = µsl × m × g
Since, Fn = m × g
m × a = (- µsl × mg)
µsl = -a/g
= 2.4/9.8
= 0.245
