H2O is how you write the formula for water
Explanation:
Water (H2O) as a polar covalent molecule has its arrangement of oxygen and hydrogen atoms where one end (hydrogen) has a partially positive charge while the other side (oxygen) had a partially negative charge.
It is also capable of forming hydrogen bonds with polar molecules. Each water molecule can form two hydrogen bonds involving their hydrogen atoms and two further hydrogen bonds using the hydrogen atoms attached to neighboring water molecules.
Magnitude of acceleration = (change of speed) / (time for the change)
Change of speed = (speed at the end) - (speed at the start)
Change of speed = (18 m/s) - (0 m/s) = 18 m/s
Time for the change = 22 sec
Magnitude of acceleration = (18 m/s) / (22 sec)
<em>Magnitude of acceleration = 0.818 m/s²</em>
This is a concept of momentum. In equation, momentum is the product of force and distance. When a ball is thrown, its force is constant all throughout unless disturbed by an external force. Therefore, force is the constant of proportionality that relates momentum with distance. When you block a ball from a given distance, you would feel the great force on your hand. In order to reduce the force, you have to follow the direction of the force in order to minimize the impact. By doing this, you gradually decrease the momentum of the ball.
Answer:
D. The direction of the force will change and it will point to regions of lower potential energy.
Explanation:
Direction will change because now you will have the opposite charge. It will still move to the lower potential because of the law of conservation of energy.
