according to the question are microwaves and X-rays
Nothing will happen to the magnetic field.
BUT If you're talking about the magnetic force , then when changing the current direction , the direction of the magnetic force will be reversed.
(You'ld like to know :
-Changing direction of current ONLY , reverses the direction of magnetic force.
-Changing direction of Magnetic field only (poles of magnet) , reverses the direction of magnetic force.
-Changing the direction of both , magnetic field and current , doesn't effect direction of magnetic force.)
N.B : Magnetic Force is experienced only when direction of current is PARALLEL to direction of magnetic field .
--> Flemming Left Hand Rule is used to know direction of magnetic force.
Hope This Helps.
Answer: The incident ray and the reflected ray and the normal will be parallel to each other.
Explanation:
The normal is perpendicular to the surface of the mirror or the reflective surface.
According to the law of reflection which state that:
The angle of incidence is always equal to the angle of reflection on a smooth surface.
If a light ray is incident on a reflective surface along the normal. The angle of incidence will be at 90 degrees which will be perpendicular to the surface of the mirror, the reflected ray will bounce back likewise at the same angle which will be perpendicular to the reflective surface.
Both the incident ray and the reflected ray and the normal will be parallel to each other.
Answer:
108 extended days
Explanation:
Regular school hours a day = 6 hr
No. of school days to make up by extending the regular hours = 3 days
Amount of time added to the regular hours of school = 10 min
No. of extended school days to make up the 3 school days by following the above mentioned criteria be x.
Time of school hours in 3 days = 
are required to make up 3 days of school having 6 hours of regular timing with 10 minutes of add-on time each day.
