Answer:
As they vibrate, they pass the energy of the disturbance to the particles next to them, which pass the energy to the particles next to them, and so on. Particles of the medium don't actually travel along with the wave. Only the energy of the wave travels through the medium
Answer and Explanation:
Data provided as per the question is as follows
Speed at point A = 20 m/s
Acceleration at point C = 

The calculation of the magnitude of the acceleration at A is shown below:-
Centripetal acceleration is

now we will put the values into the above formula
= 
After solving the above equation we will get

Tangential acceleration is

Answer:

Explanation:
To give a solution to the exercise, it is necessary to consider the concepts related to magnetic flux and Faraday's law of induction. Faraday's law states that the voltage induced in a closed circuit is directly proportional to the speed with which the magnetic flux that crosses any surface with the circuit as an edge changes over time.
It is represented under the equation,

Where,
is the induced electromotive force
N = Number of loops
= Time
= Magnetic Flux
For definition the change in magnetic flux is:

Where,
B= Magnetic field
Substituting at the first equation we have


Our values are given by,
N = 1 turn


r = 1.6mm


Replacing,


<em>Therefore the magnitud of the induced emf around a horizontal circle of tissue is
</em>
Answer:
D) Reduce the time interval during which the magnitude of the field increases.
