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 (
), medido en joules, que reducida a:
(1)
Donde:
- Masa del montañero, medido en kilogramos.
- Aceleración gravitacional, medida en metros por segundo al cuadrado.
- Distancia vertical de ascenso del montañero, medida en metros.
Si tenemos que 
, 
y 
, entonces el trabajo realizado por el montañero para subir es:
El trabajo realizado para subir los últimos 500 metros es 318727,5 joules.
An atom with a greater number of protons than electrons will be positively charged. An atom with a a greater number of electrons will be negatively charged.
Prevailing definitions of climate are not much different from “the climate is what you expect, the weather is what you get”. Using a variety of sources including reanalyses and paleo data, and aided by notions and analysis techniques from Nonlinear Geophysics, we argue that this dictum is fundamentally wrong. <span>In addition to the weather and climate, there is a qualitatively distinct intermediate regime extending over a factor of ≈ 1000 in scale.Climate changes is projected to affect individual organisms, populations, ... Overall, there is a strong correlation between topographic slope and velocity from ... the ecosystems they live in—will adapt to these changes, or if they even can.</span>
Answer:The answer is B , 0.20 m/s south
Explanation:
Answer:
The extent of greenhouse effect on mars is 
Explanation:
From the question we are told that
The albedo value of Mars is 
The albedo value of Mars is 
The surface temperature of Mars is 
The surface temperature of Venus is 
The distance of Mars from the sun is 
The distance of Venus from sun is 
The radius of the sun is 
The energy flux is 
The solar constant for Mars is mathematically represented as
![T = [\frac{E R^2 (1- A_1)}{\sigma d_m} ]](https://tex.z-dn.net/?f=T%20%3D%20%5B%5Cfrac%7BE%20R%5E2%20%281-%20A_1%29%7D%7B%5Csigma%20d_m%7D%20%5D)
Where 
is the Stefan's constant with a value 
So substituting values
So the greenhouse effect on Mars is
