Answer:

\frac{mo}{mi} = 2.34

Explanation:

Given data:

exhaust velocity = 2.455 km/s

specific impulse = 294 second

\Delta V = Ve ln\frac{mo}{mi}

\Delta v = velocity

Ve = effective exhaust velocity

Ve = Isp\time s g_0

Isp specific impulse

g_o = standard gravity

vE = 294 \times 9.8 = 2881.2 m

from above equation we have

\frac{mo}{mi} = e^{\frac{\Delta v}{Ve} [tex]\frac{mo}{mi} = e^{\frac{2455}{2881.2}       [ 2.455 km/s = 2455 m/s]

\frac{mo}{mi} = 2.34

If the contour interval is 50 meters on this map, then the line between 500 and 600 has an elevation of
Papessa [141]

Answer:

The line between 500 and 600 has an elevation of 550.

Explanation:

The contour interval represents the vertical difference between the contour lines. This is for better orientation on the map, easier calculating of elevation, as well as for an easier understanding of the relief. In this case, we have lines that are set at 500 meters and 600 meters of elevation, but there is also a line between them.

The line between, or rather the contour line between them, can easily be found out as to what elevation it is set on. We have information that the contour interval on the map is 50 meters, so we can do this either by adding 50 on 500 or minus 50 out of 600, anyway we will get the correct result.

500 + 50 = 550

600 - 50 = 550

We get a result of 550, meaning that the contour line between 500 meters and 600 meters is set at 550 meters of elevation.

As air temperatures increase, evaporation increases. Warmer temperatures also increase the capacity to absorb water vapor. More
gavmur [86]

Answer:

Greenhouse gases

Explanation:

  • The greenhouse gas raises the temperature by trapping the earth radiant heat inside the atmosphere and warming also increases the accumulation of the atmospheric water and most abundant in the greenhouse gases. And this accelerates the greenhouse effects.
