a rocket takes off from Earth's surface accelerating straight up at 47.2 miles per second calculate the normal force( in N) acting on an astronaut of mass 88.9 kg, including her space suit. ( assume the rocket initial motion parallel to the +y- direction. Indicate the direction with the sign of your answer.)

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics? a. the first law describes how thermal energy is conserved but not the direction it moves. b. the first law describes the direction thermal energy moves but not how it is conserved. c. the first law describes how thermal energy can be created but not how it can be destroyed. d. the first law describes how thermal energy can be destroyed but not how it can be created.
