Un montañero de 65kg de masa ha ascendido a la cima del Everest, la montaña más alta del mundo de 8848m de altura sobre el nivel
andrew-mc [135]

Answer:

El trabajo realizado para subir los últimos 500 metros es 318727,5 joules.

Explanation:

Por la definición de trabajo sabemos que el montañero debió contrarrestar trabajo causado por la gravedad terrestre. Si asumimos que el cambio de la altura es muy pequeño en comparación con el radio del planeta (6371 kilómetros vs. 0,5 kilómetros), entonces podemos considerar que la aceleración gravitacional es constante y la ecuación de trabajo (\Delta W), medido en joules, que reducida a:

\Delta W = m\cdot g\cdot \Delta z (1)

Donde:

m - Masa del montañero, medido en kilogramos.

g - Aceleración gravitacional, medida en metros por segundo al cuadrado.

\Delta z - Distancia vertical de ascenso del montañero, medida en metros.

Si tenemos que m = 65\,kg, g = 9,807\,\frac{m}{s^{2}} y \Delta z = 500\,m, entonces el trabajo realizado por el montañero para subir es:

\Delta W = (65\,kg)\cdot \left(9,807\,\frac{m}{s^{2}} \right)\cdot (500\,m)

\Delta W = 318727,5\,J

El trabajo realizado para subir los últimos 500 metros es 318727,5 joules.

How does an insulator stop the flow of an electric current? Question 2 options: insulator keeps the electrons in the insulator f
pickupchik [31]
Electrons in an insulator do not move readily. This is because insulators are objects whose internal electric charges do not flow freely. They impede the flow of electrons from one atom to another atom, thus restricting the flow of electricity. Insulators are electrically inactive and the are used to stop the flow of electric current.

A coil has an inductance of 5 H and a resistance of 20 Ω. If a DC voltage of 100 V is applied to the coil, find the energy store
nadya68 [22]

Answer:62.5 J

Explanation:

Given

Inductance(L)=5 H

resistance(R)=20 \Omega

Voltage(V)=100 V

Current=\frac{100}{20}=5 A

Current in L-R circuit is given by

I=I_0\left [ 1-e^{-\frac{Rt}{L}}\right ]

and Power=i^2R+Li\frac{di}{dt}[/tex]

For Steady state i.e. att=\infty

I=I_0

Energy Stored is E=\frac{Li^2}{2}

E=\frac{5\times 5^2}{2}=62.5 J
