I believe that the answer is A but correct me if i’m wrong
ANSWER and EXPLANATION
We want to identify if there will be an electric field and a magnetic field around the two sticks electrified by charges of opposite signs.
An electric field is a physical field that surrounds electrically charged particles and exerts a force on other charged particles in the surrounding.
This implies that the presence of electric charges on both sticks generates electric fields on them. Since the two charges are opposite, the electric force acting on them will be attractive.
Hence, there is an electric field.
A stationary charged object produces an electric field, as explained above, but will only produce a magnetic field if there is a motion of the object.
Hence, except the two sticks are caused to move, there will be no magnetic field around them.

Answer:
Please see below as the answer is self-explanatory.
Explanation:
- The visible range extends roughly from 400 nm (violet) to 700 nm (red).
- Below the violet is the ultra-violet spectrum (with higher energy) and above red, we have the infra-red spectrum.
- The wavelengths in the range of 650 to 690 nm have red as the dominant color.
Answer:true
Explanation:
The lower the refractive index,the faster the velocity of light
