Answer:
A capacitor with capacitance C is initially charged with charge q. At time t=0, a switch is thrown to close the circuit connecting the capacitor in series with a resistor of resistance R. (see image below)
What is the current I0 that flows through the resistor immediately after the switch is thrown? Express your answer in terms of any or all of the quantities q, R, and C.
Explanation:
charge on the capacitor,
q = CV
C is the capacitance of the capacitor
V is the voltage across the capacitor
Determine the current flowing through the resistor after the switch is thrown
According to Ohm’s law, current flowing through the resistor is ,
V is the voltage across the resistor
R is the resistance of the resistor
since
Current through the resistor immediately after the switch is thrown
Answer:0.5
Explanation:
Given
Piece of taffy slams in to sticks to another identical piece and stuck into it.
Let m be the mass of taffy and u be the initial velocity of taffy and v be the final velocity of system.
Conserving momentum
Initial kinetic energy
Final Kinetic Energy
change in kinetic energy
change in kinetic energy will contribute in heat energy
thus fraction of kinetic energy converted in to heat
