Explain why stationary waves are seen only certain frequencies (3 marks)​

Physics
1 answer:
Anettt [7]3 years ago
4 0

Explanation:

The underlying physics give rise to periodic behavior. Usually, some resonance is involved, in which the media damps waves except those at a specific frequency.

__

Only waves at a specific frequency are recognized as being "stationary." If the frequency varies, the behavior is described as "chaotic." So, it's partly a matter of definition.

What is the magnitude of the dipole moment formed by separating a proton and an electron by 100 pm
amm1812

<span>When two electrical charges, of opposite sign and equal magnitude, are separated by a distance, a dipole is established. The size of a dipole is measured by its dipole moment</span><span> . Dip</span>ole moment is measured in Debye units, which is equal to the distance between the charges multiplied by the charge

<span>Dipolemoment 'D' = e x d where e= charge and d= distance by which charge is separated. </span><span>
In this case e = charge on electron = 1.6 x10^-19 C</span>

D = 1.6 x10^-19 C ( 1x10^-10 m) =1.6x10^-29 Cm

What effect does force have on the motion of an object?
xeze [42]

Answer:

When a force acts on an object that is stationary or not moving, the force will cause the object to move, provided there are no other forces preventing that movement. If you throw a ball, you are pushing on it to start its movement. If you drop an object, the force of gravity causes it to move.

How much time will it take for a truck to travel 20 meters if it is traveling at 4 m/s?
ss7ja [257]

Answer:

<h2>The answer is 5 s</h2>

Explanation:

The time taken can be found by using the formula

t =  \frac{d}{v}  \\

d is the distance

v is the velocity

From the question we have

t =  \frac{20}{4}  \\

We have the final answer as

<h3>5 s</h3>

Hope this helps you

Explain what makes up a circuit .
ANEK [815]

Explanation:

An electrical circuit needs:

a source of electrical power (this could be a power plant or a battery)

a material along which the electricity can flow (this may be a copper wire)

something to power (this could be a bulb)

The circuit is connected in a loop. Then, the source of power pushes electrons around the wire. It lights the bulb and continues in the circuit until it is broken.

A simple circuit lights one bulb. More difficult circuits might have several switches and loops. This would allow different groups of lights to be turned on or off at the same time.

( I hope this was helpful) >;D
