If your mass, the mass of Earth, and the mass of everything in the solar system were twice as much as it is now, yet everything stayed the same size, your weight on Earth woulda. quadruple. b. be the same. c. double. d. be eight times as much as now. e. none of the above
1 answer:
Answer: a. Quadruple
Explanation:
Gravitational force = Gm1m2/r^2
(Where m1 is the mass of earth, m2 is my mass and r is the radius of earth and G is the gravity constant)
Weight = m2g
(Where g is the acceleration due to gravity)
Gm1m2/r^2 = m2g
Twice the masses
F = G(2m1)(2m2)/r^2
F = 4Gm1m2/r^2
The gravitational force has increased 4 times, this means that my weight on earth will quadruple

If she bends forward
Explanation:
because the equilibrium of gravity will not stay the same causing her to move forward
Answer:
higher is safer
Explanation:
because it is a wet slippery surface, you would need more friction on the tires, to get more traction in the slippery wet road, if you had low friction you would not move anywhere and or could swerve off somewhere
