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
Answer:
10 hours
Explanation:
If the plane flies at 500 miles per hour, it flies 500 miles every hour. So, to find out how many hours it will take to fly 5000, you simply do 5000/500.
