As per right hand thumb rule if we put our thumb of right hand along the current in the wire then curl of fingers will show the direction of magnetic field.
So here as we can see the fingers in the above case is curled such that in front position its showing towards right.
So the direction of magnetic field near the student in front position must be towards Right.

Answer: The amount of movement of the particles depends on the amount of <u>force</u> acting on them and their relationship to other atoms.
Explanation:
The inter-atomic force determines the inter-atomic distance which governs the amount of movement of the particles.
For example in solids, the inter-atomic force is stronger and hence, the distance between any atoms is very very small which restricts the movement of the particles. On the other hand, in case of liquids and gases, the inter-atomic forces are not very strong and there is more distance between the atoms which allows free movement of particles.
Answer:
One when it enters the glass slab from air and second time when it enters the air through glass slab. When light rays travelling through air enters glass slab, they get refracted and bend towards the normal. Now the direction of refracted ray changes again when it comes out of the glass slab into air.
Answer:
t = 4.28 s
Explanation:
The horizontal speed of a marble = 7 m/s
The horizontal displacement covered by the marble = 30 m
We need to find the time for which the marble is in air. Let the time is t. Using the formula for speed to find it as follows :

So, it will in the air for 4.28 s.
