Answer:
An open circuit is one where the continuity has been broken by an interruption in the path for current to flow. A closed circuit is one that is complete, with good continuity throughout. A device designed to open or close a circuit under controlled conditions is called a switch.
In other words, a closed circuit has a complete path for current to flow, whereas an open circuit doesn't, which means that it's not functional. open circuit is a circuit which is not completed. Any circuit which is not complete is considered an open circuit.

<u> </u> <span><span> No. Neutron stars are the remnants of very large stars that have supernova'd. Anything below 1.44 solar masses becomes a dwarf, anything above 5 solar masses becomes a black hole. Everything in between becomes a neutron star (or quark star, but it's not proven).</span>

<span><span>The answer is A.
</span><span>Chlorine is found in group7A of the periodic table. This means that when they are neutral, (electrons and protons are equal), they lack 1 electron to complete the octet or eight valence electrons to be stable. This will result in Chlorine having to gain an electron. Since it gained an electron, that means the electrons outnumber the protons by 1, which will result in a negative charge of -1. </span></span>
Answer:
480
Explanation:
resistance equals to potential difference divide by electric current
120÷0.25
=480
Answer:
8.3m/s
Explanation:
Given parameters:
mass of clay ball = 5kg
Speed of clay ball = 25m/s
mass of clay ball at rest = 10kg
speed of clay ball at rest = 0m/s
Unknown:
Velocity after collision = ?
Solution:
Since the balls stick together, this is an inelastic collision:
m1v1 + m2v2 = v(m1 + m2)
5(25) + 10(0) = v (5 + 10)
125 = 15v
v = 8.3m/s
