Answer:
The Velocity at which it travels, and the Distance from start to finish.
Explanation:
Calculate V*D=T which is Velocity*Distance=Time.
Answer:
The correct answer is option D.
Explanation:
From the given options the reaction which is not a double replacement reaction is:

This because the above reaction is an example of single replacement reaction.

Whereas;
Double replacement reaction is a type of chemical reaction in which exchange of ions among the reactants take place.

Answer:
velocity in which the space described varies from instant to instant, either increasing or decreasing in the former case called accelerated velocity

Answer:
electronic communications may be disrupted
Explanation:
Solar Flares: They occur when the magnetic field lines carrying charged particle entangle and reorganize over the photosphere of the Sun. In these flares charged particles leave the surface of the Sun to travel outwards.
If these flares are directed towards Earth, they will interact with anything related to electricity and magnetism. Out of the given options third option is correct as the electronic communication will be disrupted. If the flares are strong a complete power blackout may occur and that would disrupt all the communication channel and power transmission. Such events have occurred in the past as well.
