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 distance is 54.6 m
Explanation:
Given that,
Mass = 2.0 kg
Frictional coefficient = 0.21
Initial velocity = 15 m/s
We need to calculate the acceleration
Using formula of frictional force
We need to calculate the acceleration
We need to calculate the initial velocity
Using equation of motion
Put the value
Hence, The distance will be 54.6 m.
The constant in Newton's law of gravitation relating gravity to the masses and separation of particles, equal to 6.67 × 10-11N m2 kg-2.
Sound is an example of a mechanical wave. Mechanical waves are the kinds of waves that cannot be propagated without a medium. As such, these waves cannot travel through a vacuum, just like how sound cannot travel through space, since space is a vacuum.
