in motion with the same speed and in the same direction unless acted upon by an unbalanced force

Answer from: fluffy37

According to Newton's first law, an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. All objects resist changes in their state of movement. Without an unbalanced force, an object in motion will maintain its state of movement. This is often called the law of (slow or no movement/the force of something moving). Think about/believe for instance the crash of a car with a wall. Upon contact with the wall, an unbalanced force acts upon the car to suddenly slow down it to rest. Any passengers in the car will also be slowed down to rest if they are strapped to the car by seat belts. Being strapped tightly to the car, the passengers share the same state of movement as the car. As the car speeds up, the passengers speed up with it; as the car slows down, the passengers slow down with it; and as the car maintains a constant speed, the passengers maintain a constant speed also.

Answer from: Quest

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
