a. During a rocket launch, an astronaut experiences a “g-force” (actually an acceleration) of 3.0 gs [upward], which is equal to three times the acceleration due to gravity. If the astronaut weighs 79.4 kg, what is her apparent weight during the acceleration? b. When the astronaut enters the ISS (International Space Station), she is in “free fall,” where the only force acting on her is the force of gravity applied by the Earth. What happens to her true weight and her apparent weight as she enters the ISS? Explain.

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
