Find equivalent resistance??

Physics
1 answer:
inysia [295]2 years ago
7 0

Answer:

Req = 50 Ω

Explanation:

The equivalent resistance is basically the sum of all the resistances in a circuit.

The sum of these resistances will depend whether these resistance are in series or parallel.

If the resistances are on series, the expression to use is:

R = R₁ + R₂ + R₃ + .......Rₙ   (1)

If the resistances are on parallel then the expression to use is:

1/R = 1/R₁ + 1/R₂ + ........1/Rₙ    (2)

Now, according to the picture, we have R₁ and R₄ in series, so here we have to use (1):

R₁₄ = 10 + 30 = 40 Ω

R₂ and R₃ are in parallel so we use (2):

1/R₂₃ = 1/20 + 1/20 = 2/20 = 1/10

R₂₃ = 10 Ω

Finally, R₁₄ and R₂₃ are in series (Because of the sum of the resistance in each side, they are now forming one resistance in each side), therefore, we use (1) again to get the equivalent resistance of the whole circuit:

Req = 10 + 40

<h2>Req = 50 Ω</h2>

Hope this helps

Name the apparatus used to measure friction force? PLEASE HELP AS SOON AS POSSIBLE
melisa1 [442]
There is no apparatus for it. It is either use something like ruler and table and rub together or rub our hands, and friction force will be showed.

Pam, wearing a rocket pack, stands on frictionless ice. She has a mass of 49 kg. The rocket supplies a constant force for 22.0 m
ss7ja [257]

Answer:

Magnitude of the force is 4350N

Explanation:

As the woman accelerates at a distance of 22 m to go from rest to 62.5 m / s, we can use the kinematics to find the acceleration

v² = v₀² + 2 a x

v₀ = 0

a = v² / 2x

 a = 62.5²/(2 × 22)

 a = 88.78m/s²

the time you need to get this speed

     v = v₀ + a t

     t = v / a

     t = 62.5 / 88.78

     t = 0.704s

Let's caculate the magnitude of the force

F = ma

= 49 × 88.78

= 4350.22

≅ 4350N

Magnitude of the force is 4350N

     t = 1,025 s

      a = 55.43 m / s²

A body is electrically neutral. Does it mean that it has no charge?<br>​
vova2212 [387]

Answer:

If a body is electrically neutral it means it has no net charge.

Explanation:

Because it has the same number if protons as it does electron , which are opposite charges that offset eachother.
