Can be Doppler shifted, reflected, refracted,
1 answer:
Waves: can be Doppler shifted, reflected, refracted, diffracted, and can undergo constructive and destructive interference.
A wave refers to a disturbance in a medium that progressively transports energy from its source to another location, without transporting matter.
In Physics, there are two main (2) types of wave and these are;
- <u>Mechanical waves:</u> an example is sound wave, which requires a medium for its propagation.
- <u>Electromagnetic waves:</u> an example is light wave, which doesn't require a medium for its propagation and can travel through a vacuum or an empty space.
Basically, some of the phenomenon associated with waves include the following:
I. Doppler shift (Doppler effect).
II. Reflection.
III. Refraction.
IV. Diffraction.
V. Constructive interference.
VI. Destructive interference.
In conclusion, all waveform can be Doppler shifted, reflected, refracted, diffracted, and can undergo constructive and destructive interference.

Answer:
44 N
Explanation:
The electrostatic forces between two charges is given by:
where
k is the Coulomb's constant
q1 and q2 are the two charges
r is their separation
We notice that the force is directly proportional to the charges.
In this problem, initially we have a force of
F = 22 N
on a q2 = 4.0 C, exerted by a charge q1.
If the charge is doubled,
q2 = 8.0 C
This means that the force will also double, so it will be
Answer:
15.825 m
Explanation:
t = Time taken = 2.5 s
u = Initial velocity = 6.75 m/s
v = Final velocity = 5.91 m/s
s = Displacement
a = Acceleration
Equation of motion
The distance Rickey slides across the ground before touching the base is 15.825 m
