Answer:
<em><u>Given: </u></em>
m1 = 7 kg
V1 = 12 m/s
m2 = 25 kg
V2 = 6 m/s
<em><u>To find:</u></em>
Combined speed of two balls stick together after collision V = ?
<em><u>Solution:</u></em>
<em>According to law of conservation of momentum,</em>
m1V1 + m2V2 = (m1+m2)V
7×12 + 25×6 = (7+25)V
84 + 150 = 32V
V = 234/32
V = 7.31 m/s
Combined speed of two ball is 7.31 m/s

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: I believe the answer is C. Higher Volume.
Explanation: I apologize if I am incorrect.
Answer:
Dynamic Equilibrium are stable because there is an equal rate of transition between reactants and products, or between the forward and the reverse process, in a back and forth manner, such that the net change of the concentration or system is zero, and therefore, there are no excess force factor, tending to create a different outcome
Explanation:
Dynamic equilibrium, in physics and in chemistry, is the equilibrium experienced by a system that undergoes change, where however, both the forward and the reverse effect of the change are taking place.
Answer:
dispersion
As per your query the splitting of white or visible light into its component colours is known as dispersion. The splitting of white light when it passes through a glass prism into its constituent spectrum of colours is hereby known as dispersion.
