1. Which of the following will produce current in the wire (cause a light bulb to flicker). Mark ALL that apply! *
A stationary magnet within 4 coils of wire
A stationary magnet outside of 4 coils of wire
A magnet flipping polarity within 2 coils of wire
A magnet flipping polarity within 4 coils of wire
A magnet moving towards 4 coils of wire
A magnet moving away from 4 coils of wire

frequency or wavelenth of em radiation in a vacuum

radiation

explanation:

heat is transmitted by radiation

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
