Answer:
let current flow be x
Explanation:
than we know potential difference = energy supply / charge then 120 = 10 /x then x=12 therefore pd = 12 v
A gerund usually ends wit -ing, so we must find the word that includes that.
Loading includes ing at the end.
Final answer: b. loading
The iron filings aligned themselves in a pattern, along with the magnet connecting the north and south poles. This creates the “magnetic field”. Interacting with a metal object in between the magnetic properties of the metal interact with the magnet, expressing signs of magnetic force acting on it and the metal, pulled together letting you see the see the effects of the magnetic fields using iron filings.
Answer: t=4.6*R*L
Explanation: In order to explain this problem we have to take into account the expression for the current in a RL electric circuit, which is given by:
where If is the final current for RL circuit If (emf/R)
Considering the final current is getting when I(t) = 0.99*If we have:
reoganising the terms we have:
e^(-t/R*L)=(1-0.99)
ln(e^(-t/R*L))=ln(0.01)
then t=4.6*R*L
