This speed is measured with respect to the space station the spacecraft was originally launched from. in interstellar space the gravitational pull from the stars is negligible, because the stars are extremely far. the spacecraft turns its main rocket engine on for a time period of 6.5 hours. the rocket engine provides a thrust of 896 n of force. what is the new speed of the craft after the engine is turned off? the mass of the spacecraft is 1380 kg. the rocket engine is very efficient, it uses only a very small amount of rocket fuel during this whole acceleration process without changing the mass of the craft.

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
