While spinning in a centrifuge a 70.0 kg astronaut experiences an acceleration of 2.00g, or twice the acceleration due to gravity on the earth. what is the centripetal force acting on her? a.)6.86*10^3n b.)1.37*10^3n c.)1.40*10^2n d.)3.46*10^4n

Contrast the force of gravity between these pairs of objects a 1 kg mass and a 2 kg mass that are 1 m apart and two 2 kg masses that are 1 m apart
