Well if you didn't you could make mistakes, which would lead ,in the best case, at a fail of the circuit , or if it goes out of control it could be dangerous
for example you have to know that the wires become hot and they loose their abbilitys as connecters(the hotter it will, the more energy you lose becouse the R will be bigger)
The type of energy that depends on position is called
kinetic energy
Answer:
So I never really knew you
God, I really tried to
Blindsided, addicted
Felt we could really do this
But really I was foolish
Hindsight, it's obvious
Explanation:
Answer:
The coefficient of kinetic friction = 0.026
Explanation:
An 56 kg sled is being pulled across the snow, at constant speed,by a horizontal force of 15 N.
Here we have to note that the weight is pulled at a constant speed . This means that the net force acting on the weight is zero.
The external force acting on the body is in the forward direction and the friction acts in the backward direction.
Friction increases as the mass of the body increases.
Friction = 
We now equate this to the external force of 15 N.
15 = 
= 
= 0.026
The coefficient of kinetic friction = 0.026
Radioactive isotopes of an atom aren't as stable as you would think, so the correct answer is: C. Less Stable
(I can verify this because I took the test.)
Hope this helps! Have a wonderfully wonderful day!
Cheers mate!
