Answer: t = 0.492τ
Explanation: In a circuit where there is a resistor and a capacitor, the equation for a charging capacitor is given by:
where:
is the equilibrium charge
q is the charge at time t
RC is time constant also called τ (tau)
For this problem, the circuit is charged to 39%, which means: q = 
0.39 = 1 - 
= 0.61
= ln(0.61)
-t = ln(0.61)τ
t = 0.492τ
For the condition to be met it is needed 0.492 time constants must elapse.
Answer:
The hotter the substance, the more its particles move, and the higher its thermal energy. ... Heat. The heat from a heater. *Let's think about that cup of hot chocolate. ... Some matter changes from solid to liquid to gas as its particles heat, vibrate and separate. ... Boiling a kettle is an example of both thermal and kinetic energy.
