A short circuit is said to have occurred when two nodes of a circuit at different voltages are abnormally connected
There is said to be a short circuit when; <u>One part of a parallel circuit has a very low resistance and almost all the current will flow through this part and very little current will flow through the other part</u>
<u />
The correct option is option B.
Reason:
A circuit has to be closed or the the current path has to be closed for
current to flow. A short circuit occurs when current in a circuit flows
through an abnormal path, such as a bridge in a connection to a load that
creates a parallel path for current flow.
Almost all the current flows through the parallel path due to the low
resistance in the connection (almost zero) and the proximity to the power
source, thereby preventing current from reaching its intended destination
Therefore, the correct option is option B.;

Answer: 12.5 km/s
I don't really know how to explain this, but here is your answer.
D) Kilograms is the standard unit of mass
Alot as far as i know unless you need it in formal terms.
Answer:
this statement describes meteor's velocity,
because velocity is a vector quantity which has both magnitude as well as a specific direction and here the meteor's direction is specified in the statement hence we conclude that this statement describes meteor's velocity as well as speed too.
