Explanation:
It is given that, An astronaut is in equilibrium when he is positioned 140 km from the center of asteroid X and 481 km from the center of asteroid Y, along the straight line joining the centers of the asteroids. We need to find the ratio of their masses.
As they are in equilibrium, the force of gravity due to each other is same. So,

So, the ratio of masses X/Y is 0.0847
Explanation:
Remember Newton's Second Law.

If the force acting on both bikers is the same, we can look at the relationship between acceleration and mass.
If Biker 1 has a mass of 10kg and Biker 2 has a mass of 20kg, and both are being acted upon by a force of 100 N, let's see what that looks like. 

So, given the same force, an object with GREATER mass will have less acceleration.
Answer:

Explanation:
The radius of the circumference described by a particle in a cyclotron is given by:

m is the particle's mass, v is the speed of the particle, q is the particle's charge and B is the magnitude of the magnetic field.
Kinetic energy is defined as:

Solving this for mv:

Replacing (2) in (1):

For protons, we have:

For alpha particles, we have:

Dividing (4) in (3):

Answer:
The difference is the way the molecules are arranged and the way they move
Explanation:
Water molecules in liquid water are constantly sliding past and bumping into each other; they keep moving from one place to another. The molecules of water in water vapor are far apart and moving freely.
G as in grams? Because what I got is 0.0602 from my calculator. So I'm not sure if that's what you are looking for.
