Answer:
emf induced in the loop, at the instant when 9.0s have passed = 1.576 * 10 ⁻² V.
Direction is counter clockwise.
Explanation:
See attached pictures.
Answer:
The equation for acceleration can be rewritten as B to calculate the net force acting on an object when its mass and acceleration are known.
Explanation:
I hope that helps! (B is the answer)
Electric field lines of positive charges are always radially outwards
So here all field lines must have tendency to move out radially as well as two field lines never intersects with each other
So here field lines also do not intersects with each other
So overall the figure C is perfectly representing the field lines of two positive charges as these lines are not intersecting and also originating from two positive charges.
So answer must be
<u><em>FIGURE C</em></u>
Answer: Electric field vector is created by an electric force of a charged particle.
Explanation: The direction of the field vector can be determined by applying Coulomb’s Law which explains the electric force between charge particles. If q is positive the force is repulsive, to a test charge ( which is positive always ) and if q is negative the force is attractive to a test charge.
Answer:
Red line is reflected ray.
Explanation:
According to the given figure, the blue line represent the incident ray. It strikes the surface and reflection occurs. The dotted line shows normal.
After reflecting the surface, the ray of light is reflected. Red line shows the reflected light.
In this case, the laws of reflection follows i.e. the angle of incidence is equal to the angle of reflection.
