Mass driver constrained by a limited amount of onboard spacecraft power. Thrust and momentum from exhaust, per unit mass expelled, scales up linearly with its velocity (momentum = mv), yet kinetic energy and energy input requirements scale up faster with velocity squared (kinetic energy = mv). Too low exhaust velocity would excessively increase propellant mass needed under the rocket equation, with too high a fraction of energy going into accelerating propellant not used yet. Higher exhaust velocity has both benefit and tradeoff, increasing propellant usage efficiency (more momentum per unit mass of propellant expelled) but decreasing thrust and the current rate of
Mercy Multiplied transition to this new name on January 28, 2011. Mercy Multiplied also opened homes in St Louis, Missouri and Sacramento, California in 2005 and 2009 respectively. To date, Mercy Ministries has disclosed anticipated homes to be opened in Washington, D.C., North Carolina, Los Angeles, Florida, Vietnam, Peru and South Africa. United States International Australia While the Mercy Multiplied website states they are a non-denominational Christian organization, Mercy Multiplied are also considered to be evangelical, charismatic and fundamentalist, both as an organization and in their approach to treatment. The Mercy Multiplied website states that the founder, Nancy Alcorn, established the following
