¿Una corriente eléctrica sin resistencia puede fluir constantemente sin fuente alguna de potencia? Explique.

Physics
1 answer:
frosja888 [35]3 years ago
4 0

Answer:

No.

Explicación:

No, una corriente eléctrica sin resistencia no puede fluir constantemente sin ninguna fuente de energía porque la fuente de energía proporciona electrones para el flujo continuo de corriente en el circuito. Si fluye corriente por el cable, debe haber resistencia en el circuito. La fuente de energía proporciona corriente eléctrica continua al cable para que fluya y el cable tiene resistencia, por lo que parte de la corriente eléctrica se pierde durante su flujo debido a esta resistencia. Entonces podemos decir que la fuente de energía es necesaria para el flujo constante de corriente eléctrica.

Decide whether each statement describes mass or weight.
vova2212 [387]

<u>Mass</u>

  • Mass is measured in kilograms.
  • Mass does not change when gravity changes.
  • Mass is the amount of matter in something.

<u>Weight</u>

  • Before I answer, we have to know weight formula. Weight = mass × acceleration due to gravity.
  • Therefore, weight is measured in Newtons.
  • Weight changes when gravity changes. This is because weight is dependent on acceleration due to gravity.
  • Weight is a gravitational force.

Hope you could understand.

Sarah is measuring how fast a marble rolls down a ramp when she changes the height of the ramp. W hitch type of graph would most
alexgriva [62]

The type of graph that would most appropriately display Sarah's data is a line graph.

<h3>What is a line graph?</h3>

A line graph, sometimes referred to as a line plot or a line chart, is a graph in which individual data points are connected by lines. A line graph shows numerical values over a predetermined period of time.

Line graphs are frequently used in finance to show the historical price movement of an asset or instrument. To monitor changes over both short and long time periods, line graphs are utilized. Line graphs can be used to compare changes for multiple groups over the same time period.

In this case, it should be noted that Sarah wants to compare the speed and the height. Therefore, the line graph and s appropriate.

slader A transcontinental flight of 4890 km is scheduled to take 40 min longer westward than eastward. The airspeed of the airpl
11111nata11111 [884]

Answer:

v_{s}=65.2km/h

Explanation:

Given data

Flight distance S=4890 km

Time difference Δt=t₂-t₁=40 min

Air speed of plane=980 km/h

To find

Speed of jet stream

Solution

When moving in the same direction as the jet stream time taken as t₁=d/(v+vs),v is velocity of plane and vs is velocity of plane

While moving in opposite direction t₂=d/(v+vs)

So

t_{2}-t_{1}=\frac{d}{(v-v_{s}) } - \frac{d}{(v+v_{s}) }\\t_{2}-t_{1}=\frac{d(v+v_{s})-d(v-v_{s})}{(v-v_{s})(v+v_{s})} \\t_{2}-t_{1}=\frac{2dv_{s}}{(v)^{2} -(v_{s})^{2} }\\0.666667h=\frac{2(4890km)v_{s}}{(980km/h)^{2} -(v_{s})^{2} }\\0.666667((980km/h)^{2} -(v_{s})^{2})=9780v_{s}\\640267-0.666667(v_{s})^{2}-9780v_{s}=0\\0.666667(v_{s})^{2}+9780v_{s}-640267=0

Apply quadratic formula to solve for vs

So

v_{s}=65.2km/h
