Physics
1 answer:
Mrrafil [7]2 years ago
8 0

La respuesta es 3 ohmios

Resistencia total = (1/12 + 1/4) ⁻¹

= (1/3) ⁻¹

= 3 ohmios

Por ejemplo, dos resistencias, R1 y R2 están en serie, la resistencia combinada es R1 + R2.

Cuando se conecta en paralelo, la resistencia total es el recíproco de (1 / R1 + 1 / R2)

En este caso las resistencias están en paralelo

Espero que esto ayude, que tengas un día bendecido!

How does one get 8.0 A? The answer is D
ra1l [238]

I don't know why the answer is D , because I can't see the list of choices.


The only way to get 8.0 Amps is by making a serious mistake.

The current in the second picture is 4.0 Amps.


If the resistors are identical, then the effective resistance of

two resistors in parallel is 1/2 the resistance of each one.


The resistance in the second picture is 1/2 the resistance

in the first picture.


Current = (voltage) / (resistance)


Cutting the resistance in half causes the current to double.


If the current was 2.0 Amps in the first picture, it's 4.0 Amps

in the second picture.

maxonik [38]

Answer:

A. There is a localization of positive charge near the door handle.

Explanation:

  • When on a cold morning a person wearing cotton/ polyester cloth walking on the carpet moves toward his car then due to friction between the feet and the carpet there are transfer of electrons from the carpet to our feet, and since our body is a good conductor of electricity the charges spread throughout on the surface of or body.
  • When the person brings his hands close to the neutral conducting door of the car it gets induced with equal intensity of opposite charge to our hands thus having a concentration of positive charges near to the hand on the car's door is developed as a result of polarization within the conductor.

Two airplanes leave an airport at the same time. The velocity of the first airplane is 650 m/h at a heading of 60.5 ◦ . The velo
Assoli18 [71]
First, illustrate the problem as shown in the attached picture. Next, let's find the distance traveled by planes A and B after 2.9 h.

Distance of A: 650 m/h * 2.9 h = 1,885 m
Distance of B: 560 m/h * 2.9 h = 1,624 m

Then, we use the cosine law to determine the distance x. The angle should be: 85 - 60.5 = 24.5°

x² = 1,885² + 1,624² - 2(1,885)(1,624)(cos 24.5°)
x = √619381.3183
<em>x = 787 m</em>

rewona [7]

Answer:

\dot{m_{2}}=0.865 kg/s

Explanation:

\dot{m_1}= 0.5kg/s

from steam tables , at 250 kPa, and at

T₁ = 80⁰C ⇒ h₁ = 335.02 kJ/kg

T₂ = 20⁰C⇒ h₂ = 83.915 kJ/kg

T₃ = 42⁰C ⇒ h₃ = 175.90 kJ/kg

we know

\dot{m_{in}}=\dot{m_{out}}

\dot{m_{1}}+\dot{m_{2}}=\dot{m_{3}}

according to energy balance equation

\dot{m_{in}}h_{in}=\dot{m_{out}}h_{out}

\dot{m_{1}}h_{1}+\dot{m_{2}}h_{2}=\dot{m_{3}}h_{3}

\dot{m_{1}}h_{1}+\dot{m_{2}}h_{2}=(\dot{m_{1}}+\dot{m_{2}})h_{3}\\(0.5\times 335.02)+(\dot{m_{2}}\times 83.915)=(0.5+\dot{m_{2}})175.90\\\dot{m_{2}}=0.865 kg/s
