Answer:
a thing or things belonging to someone; possessions collectively.
Explanation:
Answer:
If there is no horizontal component to the force then it is just 0N
Explanation:
The emf induced = B*l*v where B is the flux density, l the length of the conductor and v the velocity of the conductor. In the given case B = 0.035 N/amp.meter, l = 0.86 and v = 6 m/sec
emf = 0.035*0.86*6 = 0.1806 v ≈ 0.18 v
choice: D
Answer:
D. There is a magnetic force pushing the wires away from one another.
Explanation:
When electric current flows through one wire then it will induce magnetic field now this magnetic field will exert the force on another current carrying wire
Now we know that force between two current carrying wires is given as
so here if two wire have current in same direction then two wires will attract each other
Also when current in wire is anti parallel to each other then the force between two wires is repulsive force
so correct answer will be
D. There is a magnetic force pushing the wires away from one another.
Answer: B. illuminance of a surface.
Explanation:
A. Luminous flux is the quantity of the energy of the light emitted per second in all directions.
B. Illuminance of a surface describes the quantity of light emitted by a light source or received at a surface.
C. Incandescence is The phenomenon of light emission by a body as a result of high temperature.
D. luminous intensity is the quantity of visible light that a point source radiates in a given direction.
