Use Eq. cosϕ=R/Z to show that the average power delivered by the source in an L−R−C series circuit is given by Pav = I^2rmsR .

Evgen [1.6K]

Answer:

Explanation:

In a L C R circuit, the average power is given by

$P_{av}=V_{rms}I_{rms}Cos\phi$

As given in the question

CosФ = R / Z

And we know that

$V_{rms}=I_{rms}\times Z$

$P_{av}=I_{rms}\times Z\times I_{rms}\times \frac{R}{Z}$

$P_{av}=I_{rms}^{2}\times R$

The traffic on the freeway is moving at a constant speed of 24 m/sm/s. What distance does the traffic travel while the car is mo

ExtremeBDS [4]

Incomplete question as there is so much information is missing.The complete question is here

A car sits on an entrance ramp to a freeway, waiting for a break in the traffic. Then the driver accelerates with constant acceleration along the ramp and onto the freeway. The car starts from rest, moves in a straight line, and has a speed of 24 m/s (54 mi/h) when it reaches the end of the 120-m-long ramp. The traffic on the freeway is moving at a constant speed of 24 m/s. What distance does the traffic travel while the car is moving the length of the ramp?

Answer:

Distance traveled=240 m

Explanation:

Given data

Initial velocity of car v₀=0 m/s

Final velocity of car vf=24 m/s

Distance traveled by car S=120 m

To find

Distance does the traffic travel

Solution

To find the distance first we need to find time, for time first we need acceleration

$(V_{f})^{2}=(V_{o})^{2}+2aS\\ So\\a=\frac{(V_{f})^{2}-(V_{o})^{2} }{2S}\\ a=\frac{(24m/s)^{2}-(0m/s)^{2} }{2(120)}\\a=2.4 m/s^{2}$

As we find acceleration.Now we need to find time

$V_{f}=V_{i}+at\\t=\frac{V_{f}-V_{i}}{a}\\t=\frac{(24m/s)-(0m/s)}{(2.4m/s^{2} )}\\t=10s$

Now for distance

$Distance=velocity*time\\Distance=(24m/s)*(10s)\\Distance=240m$

Problem I Marcella (see warmup problem, above) gets her car moving steadily at 4m/s but suddenly someone stops ahead to assist h

Nady [450]

Answer:

Explanation:

a) KE = (1/2) * m * ( $v^{2}$ ) = F * d = 14m * 200N = 2800 m/N or 2.8 * $10^{3}$ m/N

b) 0J and 0m/s (if Marcella stopped after going 14 meters)

c) Known from part (a) that KE = 2800 J = F1 * d1,

2800J = F1 * (14m - 1m) => F1 = 2800J/13m = 215.384 N

A car travels from Bangalore to Mumbai and returns back on 20 hrs. What is the average velocity and average speed of the car if

irinina [24]

Answer:

Explanation:

Average speed= Total distance/ Total time

Initial reading= 2200

final reading= 3800

total distance= Final reading -initial reading = 3800-2200 = 1600 km

total time= 20 hrs

Average speed= 1600/20

= 80 km/hr

CONVERTING km/hr TO m/s

To convert km/hr to m/s just multiply

Recall that,

1000m = 1 km

60 secs = 1 min

60 mins = 1 hr

( 80 × 1000 ) meters / ( 60×60 ) secs

80000m / 3600s

= 22.22m/s
