Answer:
Explanation:
Due to changing magnetic field , there will be emf induced in the region . EMF induced will create electric field which will be circular in shape and will be uniform along its circular path
The magnitude of circular electric field can be calculated as follows
We should apply Faraday law of electro magnetic induction
e = - dФ / dt = - ∫ E dl
Here Ф = π r² B
π r² dB / dt = - ∫ E dl
π r² dB / dt = E x 2π r
E = - r / 2 x dB / dt
For a circular electric field having a particular radius , magnitude of field will be constant .
The direction of electric field will be known by lenz's law
In the given case , magnetic field is upwards and it is reducing , therefore electric field induced will be such as to prevent this change of flux.
So electric field will be anticlock-wise . Hence direction of acceleration will also be anticlock-wise on proton at 1.5 cm from the centre.
Answer:
c They can only travel without a medium.
Explanation:
Electromagnetic waves are made up of electric field and magnetic field.
Here electric field will induce magnetic field and magnetic field will induce electric field.
So this type of field do not require any medium and in vacuum or air the speed of electromagnetic waves are same as speed of light
also we have different range of electromagnetic waves out of which a small range of electromagnetic waves is of visible region in which these waves are visible to us.
so correct answer is
c They can only travel without a medium.

Answer:
b .at the outer edge of the Galactic Disk
Explanation:
The sun is located on the outeredge of the galaxy. So it has an orbit within our Milky Way galaxy that is also located arround the <u>outer edge of the galactic disk</u>, and goes around in about 30 million years.
In reallity, allong its trayectory, the sun goes above and below the gallactic disk, but it stays in the outer edge of the galaxy, <u>far away from the galactic bulge and the galactic center</u>, but closer to it than the galactic halo.
