Hope this helps the answer is: <span>Relation between Electric and magnetic fields. I've read that both the electric and magnetic field vectors are perpendicular to each other in an electromagnetic wave. Passing steady current through a straight conductor shows some magnetic flux because most of the energy is wasted into outer space as magnetic lines</span>

An electric field that changes with time ( such as due to the motions of charged particles) will also influence the magnetic field of that region of space.

An electric field is a property that describes the space that surrounds electrically charged particles. A magnetic field is a field of force produced by a magnetic object or particle. This can also happen from a changing electrical field.

Hope this helps! :)

If I were to transmit a radio wave in our three dimensional world could a fourth dimensional “being” be able to receive it?

Morgarella [4.7K]

Depends. Are you talking about a mathematical 4th dimension (in which there is infinite dimensions) or some sort of etheral dimension (in which there is no scientific evidence for)

If you mean the first then yes. But it depends how these beings exist. From our understanding we only can theorize shapes in 4-d and if we assume that there is only one universe these "beings" arleady exist and thus any message in 3-d would be sent to them like a shadow ("flat").
If they exist in a alternate "plane" then you would need some method to transverse this plan and if u did, then we would easily be able to communicate, but we would at first sound like a wild animal. They either would ignore us, not understand or perceive us, or they would attempt to send back a signal (essential they are ET's)

IF you mean the second then thats some mystic stuff and its pretty creepy (although a fun read for me :P)

If a rooster laid an egg on a roof where would the egg fall left or right

Blababa [14]

Depends on how steep the roof is , maybe the egg will just stay where it is but if the roof is more to the left it will fall to the left and same goes for right !

Help ASAP PLZZZZ!! I will give brainlist to the first right person.

Answer:

1. The Speed is 390

2. The Frequency is 425 Hz

3. The Wavelength is 1.3

Explanation:

1. To find the speed of a wave you have to do the formula of speed.

Speed = Wavelength x Wave Frequency.

Speed = 1.5 * 260

= 390

Formula

F= $\frac{1}{T}\\$

F = 340 / 0.8

= 425

Formula

Wavelength = speed / frequency

Wavelength = 440 / 344 (rounded to nearest tenth if necessary)

= 1.3

Suppose a skydiver (mass =100kg) is falling towards the earth. When the skydiver is 80 m above the earth he is moving at 60 m/s

goblinko [34]

Answer:

The total mechanical energy of the skydiver is, E = 96402.6 J

Explanation:

Given data,

The mass of the skydiver, m = 100 kg

The speed of the skydiver at 80 m height, v = 60 m/s

The initial velocity of the skydiver, u = 0

Using the III equations of motion,

v² = u² + 2gs

s = v²/2g

Substituting the given values,

s = ½ 60²/ 9.8

= 18.37 m

Hence the initial total distance of the skydiver from the ground initially,

h = s + d

= 18.37 + 80

= 98.37 m

Since the total mechanical energy of a system is conserved, the total mechanical energy of the skydiver at height 'h' is equal to the total mechanical energy at height 'd'.

E = P.E + K.E

= mgh + ½ mu²

= 100 x 9.8 x 98.37 ( ∵ u = 0)

= 96402.6 J

Hence, the total mechanical energy of the skydiver is, E = 96402.6 J
