A metal wire has a resistance of 14.00 Ω at a temperature of 25.0°C. If the same wire has a resistance of 14.55 Ω at 90.0°C, wha
aliina [53]

Answer:

13.52 Ω

Explanation:

coefficient of thermal resistance be α

R₀ , R₂₅ , R₉₀ and R₋₃₂ be resistances at 0 , 25 , 90 , and - 32 degree

R₂₅ = R₀ + α x 25

R₉₀ = R₀ + α x 90

R₉₀ - R₂₅ = 65 x α

α = (R₉₀ - R₂₅ )/ 65

= (14.55 - 14) / 65

=   .55 / 65 Ω per °C,

R₂₅ = R₀ + α x 25

14 = R₀ + (.55 / 65 )x 25

=  R₀ + .2115

R₀ = 13.7885 Ω

R₋₃₂ = R₀ - α x 32

= 13.7885 -(  .55 / 65) x 32

=  13.7885 - .27077

= 13.51773 Ω

= 13.52 Ω

A gas in a closed container is heated with 10J of energy, causing the lid of the container to rise 2m with 3N of force. What is
AveGali [126]

Explanation:

For this problem, use the first law of thermodynamics. The change in energy equals the increase in heat energy minus the work done.

ΔU=Q−W

We are not given a value for work, but we can solve for it using the force and distance. Work is the product of force and displacement.

W=FΔx

W=3N×2m

W=6J

Now that we have the value of work done and the value for heat added, we can solve for the total change in energy.

ΔU=Q−W

ΔU=10J−6J

ΔU=4J

Answer is 4J

i think this may help you very much

1. Explique con sus palabras por qué el ser humano al nacer es un organismo inacabado, y que influencia ejercen en él las caract
Vlad [161]

Answer:

Todo ser humano, al nacer, es un organismo inacabado en términos tanto físicos como psicoemocionales. Es decir, el humano, al nacer, lo hace sin la posibilidad de autosustentarse en el futuro inmediato: no puede caminar, expresarse, tener pensamiento analítico ni la capacidad de resolver las problemáticas que les afectan.

Ello hace que el humano requiera para su desarrollo de un acompañamiento absoluto por parte de su madre en el período inicial de su vida, tanto para alimentarlo como para transmitirle las nociones básicas de supervivencia; y posteriormente requiera de un entorno social idóneo que le permita desarrollarse emocionalmente para poder vivir normalmente en sociedad.

Además, respecto de sus características físicas, necesita también aprender a caminar, movilizarse y demás atributos físicos que le garanticen un normal desarrollo motor, con lo cual es fundamental que dicha enseñanza provenga también del entorno que lo rodea.
