The statement about "<span>A wedge is simply a form of an inclined plane" is false. </span><span>The pivot joint
is the lever and the wedge are the blades of the scissors. This is to
efficiently exert force on an object to cut it.</span>
Answer:
The correct option is;
d) All of the above
Explanation:
a) In an electric circuit through which electric current flows, it is due to the electric charges which can be the negatively charged electrons or the positively charged protons
b) Voltage is the potential difference that results in current flowing through the circuit, therefore, the voltage is applied across the circuit through which current flows
c) The voltage which is the electric potential difference is the change in potential energy in joules of a given system due to the movement of a test charge (in Coulombs) between points in the electric field, ΔE, divided by the value of the test charge, 'q'
V = ΔE/q
Therefore, all of the above are correct.
Answer:
The value is 
Explanation:
From the question we are told that
The current is 
The inductor is 
The voltage induced is 
Generally the emf induced is mathematically represented as
Here 
is the time taken
=> 
=> 
=>
