Which of the two resistors dissipates the larger amount of power?

1 answer:

3 0

The circuit shown has a battery and two resistors, with R1>R2. Which of the two resistors dissipates the larger amount of power? Explain

Rank in order, from largest to smallest, the three currents I1 TO I3. And explain why?

The two batteries are identical and the four resistors all ahve exactly the same resistance.

a) Compare change in V(ab), V(cd), and V(ef). Are they all the same? In not, rank them in decreasing order. Explain you reasoning

b) Rank in order, from largest to smallest, the five currents I1 to I5, and ezplain why

Cuántas veces es mayor la masa del protón que la del electrón?

viktelen [127]

Answer:

Un protón es aproximadamente 1835 veces más masivo que un electrón. Si está preguntando acerca de sus dimensiones físicas, nadie lo sabe. Los científicos actualmente no saben qué tan pequeños son los electrones. ¡Son más pequeños de lo que podemos medir actualmente y pueden no tener un tamaño en absoluto!

What is the speed of an electron that has been accelerated from rest through a potential difference of 1020 V?

sashaice [31]

<span>a. KE in electron volts is 1020 eV.
b. KE in Joules is e(1020) = (1.6022E-19)(1020) = 1.634E-16
c. KE = (1/2)mv^2, so v = sqrt[2*KE/m] = 18.94E6 m/s

note: m is the mass of an electron = 9.109e-31 kg

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

Do you think there could be another period of time when so many brilliant discoveries are made in such a span of time? Why or Wh

Arada [10]

There won't be another period where many brilliant discoveries are made in such a span of time because of the high degree of advancement already.

<h3>What is Technology?</h3>

An air conditioner running with R-134a on a cycle executed under the saturationdome between the pressure limits of 0.8 MPa and 0

ohaa [14]

Answer:

The COP of the system is = 4.6

Explanation:

Given data

Higher pressure = 1.8 M pa

Lower pressure = 0.12 M pa

Now we have to find out high & ow temperatures at these pressure limits.

Higher temperature corresponding to pressure 1.8 M pa

$T_{H} = 62.9$ °c = 335.9 K

Lower temperature corresponding to pressure 0.2 M pa

$T_{L} = - 10.1$ °c = 262.9 K

COP of the system is given by

$COP = \frac{T_{L} }{T_{H} -T_{L} }$

$COP = \frac{335.9}{335.9 -262.9}$

COP = 4.6

Therefore the COP of the system is = 4.6
