A capacitor with initial charge q0 is discharged through a resistor. What multiple of the time constant τ gives the time the cap

fiasKO [112]

Answer: a) 0.13*τ ; b) 2.08*τ

Explanation: In order to explain the discharg of a capacitor through a resistor, we have to consider the following:

Q(t)=Qo* exp(-t/τ) for a lose of 1/8-th of its charge

in this case, Q(t)=7/8*Qo=7/8*exp(-t/τ)

ln(7/8)*τ=-t

then, t= -ln(7/8)*τ =0.13

For a lose of 7/8 th of its charge , we have

Q(t)=1/7*Qo*exp(-t/τ)

t=-ln(1/8)*τ=2.08

Acceleration of car is 4m/s²

Acceleration of truck is 2m/s²

Explanation:

Given parameters:

Force on the car and truck = 12000N

Mass of car = 3000kg

Mass of truck = 6000kg

Unknown:

Acceleration of car = ?

Acceleration of truck = ?

Solution:

Force is product of mass and acceleration. It is a push or a pull exerted on a body.

Force = mass x acceleration

Make acceleration the subject of the formula;

Acceleration = $\frac{Force}{mass}$

Acceleration of car = $\frac{12000}{3000}$ = 4m/s²

Acceleration of truck = $\frac{12000}{6000}$ = 2m/s²
