A charge of 90 C passes through a wire in 1 hour 15 minutes . what is the current in the wire
Answers
Time should be converted to seconds:
1h 15 min= 75min= 4500s
I=
1 hour = 3600 seconds
15 minutes = 900 seconds
1 hour 15 minutes = 4500 seconds
90 C / 4500 sec = 0.02 amperes = 20 milliamperes

Answer:
Valence electrons
Explanation:
The valence electrons are found in the outermost shell of an atom. They are the most loosely held electrons found within an atom. These valence electrons are involved and are used to form bonds when atoms combines together.
The energy required to remove these loosely held electrons is relatively low compared to electrons located in the inner orbitals. This is why when atoms combines, they use the outermost electrons to form bonds and mimic stable atoms like those of the noble gases.

Answer:
Explanation:
T=2π√l/g
to solve this for l we have to remove the square root in order to finish square root we have to take square on both side so the equation become
T²=4π²l/g
multiplying g on both side
T²g=4π²l
now dividing 4π² on both side
T²g/4π²=l
so l=T²g/4π²

Answer: The correct answer is false.
Explanation:
The electric charges can be transferred through the processes: Conduction and induction.
Conduction: In this process, the charges move from charged body to uncharged body by touching the charged and the uncharged bodies. Here, the charges flow from one body to another until the equilibrium of the charges on both bodies is attained.
Induction: In this process, the charged body is brought near to the uncharged body but without touching these together. In this process, the charge is induced on the uncharged body.
If the negatively charged body is brought near to the uncharged body then the positively charge is induced on the uncharged body.
Therefore, the electric charges cannot only be transferred through a process called conduction. The given statement is false.

What this is pretty much saying is that for every action, there is a consequence. One force connects and triggers another.
The magnitude of action and reaction are equal but the direction is opposite.
