Why would knowing the characteristics of circuits be important in designing electrical circuits?

2 answers:

8 0

Well if you didn't you could make mistakes, which would lead ,in the best case, at a fail of the circuit , or if it goes out of control it could be dangerous

for example you have to know that the wires become hot and they loose their abbilitys as connecters(the hotter it will, the more energy you lose becouse the R will be bigger)

Give an example of how a bicycle rider would accelerate? Explain the three different ways a bicyclist could

Ostrovityanka [42]

A cyclist can increase the speed of their bike in various ways such as, changing gears, positioning themselves properly, increase the pedalling rate

<h3>Ways in which a cyclist can increase the speed of a bicycle</h3>

Bicycle riders could accelerate/ increase their speed in various ways

By Changing the gears and by doing so increasing the speed
By Positioning themselves in a streamlined manner, this is so that they become aerodynamic hence they cut across airflow.
By increase the rate at which they are pedalling the bicycle.

A 0.380 kg block of wood rests on a horizontal frictionless surface and is attached to a spring (also horizontal) with a 28.0 N/

Sati [7]

Initial momentum of the Play-doh: 0.0600 x 2.60 = 0.156 kg/m/s

Total mass of the block and play-doh: 0.38 + 0.0600 = 0.44 kg.

Final momentum is mass x velocity = 0.44v

V = Initial momentum / mass

V = 0.156 / 0.44 = 0.3545 m/s

Work done by spring is equal to the Kinetic enrgy.

Work Done by spring = 1/2 *28.0 * distance^2 = 14 * d^2

KE = 1/2 * 0.44* 0.3545^2

set to equal each other:

14 * d^2 = 0.22 *0.12567

Solve for d:

d = √(0.22*0.12567)/14

d = 0.44 meters = 4.4cm

Answer:

Approximately 22.9 seconds.

Explanation:

A sound wave travel 340m in 1 sec

For 7800m it will travel;

$\frac{7800}{340} * 1$ = 22.94117647 sec

It will take approximately 22.9 seconds.

A jetliner can fly 4.9 hours on a full load of fuel. Without any wind it flies at a speed of 1.88 x 102 m/s. The plane is to mak

PSYCHO15rus [73]

Answer:

1371.26 Km

Explanation:

First of all, we need to find the velocity of the plane relative to the ground since the air has a velocity of 78.2 m/s due east and without any wind, it flies at a velocity of 188 m/s.

Thus, during the west trip, the velocity will be;

Vw = Vp - Va

Vp is velocity of plane while Va is velocity of air

and since distance/time = velocity ;

Time = velocity/distance and thus;

Time during this west period ;Tw = X/(Vp - Va)

Now during the east trip,

Ve = Vp + Va

And Te = X/(Vp + Va)

From the question, the plane can fly 4.9 hours on a full load of fuel. Let's convert this to seconds because velocity is in m/s

Thus, 4.9 hours = 4.9 x 60 x 60 = 17640 seconds

So, this time will be equal to the sum of that in the west and east directions.

Thus; T = Tw + Te

From above we know Tw and Te.

Let's substitute them into the equation;

T = [X/(Vp - Va)] + [X/(Vp + Va)]

T = X[(Vp + Va + Vp - Va)/((Vp)² — (Va)²)

T = X[(2Vp)/((Vp)² — (Va)²)

Making X the subject to obtain;

X = [T((Vp)² — (Va)²)]/(2Vp)

X = [17640((188)² — (78.2)²)]/(2 x 188)

X = 515595326.4/376 = 1371264.17m = 1371.26 Km
