Most of them would use the method generating globe in order to get the estimated distance.</span>
Answer:
D
Explanation:
Islam is the dominant religion in North Africa and the Horn of Africa.
Answer:
Explanation:
Given data:
exhaust velocity = 2.455 km/s
specific impulse = 294 second
Ve = effective exhaust velocity
Isp specific impulse
g_o = standard gravity
from above equation we have
![\frac{mo}{mi} = e^{\frac{\Delta v}{Ve} [tex]\frac{mo}{mi} = e^{\frac{2455}{2881.2}](https://tex.z-dn.net/?f=%5Cfrac%7Bmo%7D%7Bmi%7D%20%3D%20e%5E%7B%5Cfrac%7B%5CDelta%20v%7D%7BVe%7D%3C%2Fp%3E%3Cp%3E%20%5Btex%5D%5Cfrac%7Bmo%7D%7Bmi%7D%20%3D%20e%5E%7B%5Cfrac%7B2455%7D%7B2881.2%7D)
[ 2.455 km/s = 2455 m/s]
