Answer:

t = 1.659s

Explanation:

We can use the kinematics equations to solve this questions:

v = u + at

v^{2} = u^{2} +2as

where v = Final Velocity, u = initial velocity, a = acceleration, t = time, s = displacement

a) Given information from the question,

u = \frac{70km}{h} =\frac{(70*1000)m}{(1*3600)s} = 19.444m/s (Convert km/h to m/s first)

a = 2m/s^{2}

s = 35m

Now we can substitute these values into the 2nd kinematics equation to find v, final velocity.

v^{2} =(19.444)^{2} +2(2)(35)\\v=\sqrt{(19.444)^{2} +2(2)(35)} \\v= 22.761m/s (5.sf)\\

b) Now we have the final velocity, we can substitute the values into the first kinematics equation to find t , the time taken.

v = u + at

22.761 = 19.444 + 2t

2t = 22.761 - 19.444

t =\frac{22.761-19.444}{2}

t = 1.659s

Consider a series LRC-circuit in which C-120.0 uF. When driven at a frequency w = 200.0 rad s-1 the com ples impedance is given
Lina20 [59]

Answer:

(a). (i). The reactants are X_{L} =31.66\ \Omega .

(II). The inductance of the circuit is 0.1583 Henry.

(b). The resonant angular frequency is 229.4 rad/s.

Explanation:

Given that,

Capacitor = 120.0 μC

Frequency = 200.0 rad/s

Impedance = 100.0 -10j

(I). We need to calculate the X_{C}

X_{C}=\dfrac{1}{C\times\omega}

Put the value into the formula

X_{C}=\dfrac{1}{120\times10^{-6}\times200}

X_{C}=41.66\ \Omega

(II). We know that,

Formula of impedance is

Z=\sqrt{R^2+X_{L}^2+X_{C}^2}...(I)

Given equation of impedance is

Z=(100-10j)...(II)

On Comparing of equation (I) and (II)

R = 100

X_{L}-X_{C}=-10

Now, put the value of  X_{C}

X_{L=41.66-10

X_{L}=31.66\ \Omega

We need to calculate the inductance

Using formula of inductance

X_{L}=\omega\times L

Put the value into the formula

L=\dfrac{X_{L}}{\omega}

L=\dfrac{31.66}{200}

L=0.1583\ Henry

(b). We need to calculate the resonant angular frequency

Using formula of the resonant angular frequency

angular\ frequency =\dfrac{1}{\sqrt{L\times C}}

angular\ frequency =\dfrac{1}{\sqrt{0.1583\times120\times10^{-6}}}

angular\ frequency =229.4\ rad/s

Hence, (a). (i). The reactants are X_{L} =31.66\ \Omega .

(II). The inductance of the circuit is 0.1583 Henry.

(b). The resonant angular frequency is 229.4 rad/s.
