Answer:
In a coiled spring, the particles of the medium vibrate to and fro about their mean positions at an angle of
A. 0° to the direction of propagation of wave
Explanation:
The waveform of a coiled spring is a longitudinal wave, which is made up of vibrations of the spring which are in the same direction as the direction of the wave's advancement
As the coiled spring experiences a compression force and is then released, it experiences a sequential movement of the wave of the compression that extends the length of the coiled spring which is then followed by a stretched section of the coiled spring in a repeatedly such that the direction of vibration of particles of the coiled is parallel to direction of motion of the wave
From which we have that the angle between the direction of vibration of the particles of the coiled spring and the direction of propagation of the wave is 0°.
The answer for the given statement above would be option A. TRUE. It is true that the scientific revolution's advances in knowledge about the physical world led philosophers a<span>nd other thinkers to believe that if reason structured the physical world, then reason might also be found in the world of human activity and government. Hope this helps.</span>
h=5t^2
Replace what you know making the equation
h=5(4)^2
now get ride of 4^2
4^2=16
h=5(16)
now multiply 5 and 16
resulting in the answer
H=80
Answer:
A wave transfers energy as it moves away from the source.
Explanation:
A wave transfers energy as it moves away from the source. A wave is known to be a disturbance that travels through a medium and transfer energy from a point to the other without causing any permanent displacement of the medium itself.
Let's take water as an example of a medium through which wave is transfered. As the water moves away from its source, the wave generates energy. The wave produces a motion which leads to transfer of kinetic energy as the medium moves from its source since kinetic energy is the energy acquired by a body by virtue of its motion.
Answer:
The reflection and rectilinear propagation of light helps in the formation of shadows and also tells light doesn't penetrate opaque materials.
