Coulomb's law explains the force between the charges whereas Newton's law of gravitation explains the force between the masses. ... The electrostatic force may be positive or negative in the case of Coulomb's law but the force is always negative in the case of Newton's law of gravitation

It also takes energy to break the hydrogen bonds in water that must be disrupted to insert one of these sucrose molecules into solution. Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules.
I hope this helped :)
Answer:
acceleration = 15.8 m/s^2
Explanation:
Weight of rocket which acts downward is W = mass × acceleration due to gravity
w = 30.9 × 9.81
W = 303.129 N
force of 790 N acts upward and it is greater than W hence acceleration is in upward direction and is given by Newton's second law of motion as
790 - W = mass × acceleration
790 - 303.129 = 30.9 × acceleration
486.871 = 30.9 × acceleration
acceleration = 486.871 / 30.9
acceleration = 15.756 m/s^2
acceleration = 15.8 m/s^2
The railroad tracks will expand because the heat waves make them bigger
