Answer:
hey. i dont know what you tryna say but if u replying to someone else, you should use the comments section. in that way you won't lose points.
The major advantage of parallel circuit which makes it advantageous in the application of wiring rooms are the supply of equal voltage across each circuit, which is not present in series circuit.
<u>
Explanation:</u>
The use of parallel circuit is preferred over series circuit while wiring the room as the parallel gives the same voltage across every circuit which keeps it safe from damaging or burning as they give consistent voltage.
Apart from this, the parallel circuit allows you for independent operation without letting use of all the equipment present in the room. Then there is scope for additional components without changing the voltage.
The dependent variable was the time and the independent variable was thecars
Answer:
Explanation:
Let the mass of the other car is "m" and its kinetic energy is
now the mass of the first car is two and half times and its kinetic energy is half that of other car
so we will have
now speed of both cars is increased by value of 9 m/s
so now we will have same kinetic energy for both cars
so speed of first car is
