Maritime polar air mass comes from the northern part of the pasific ocean and that air mass goes to Utah.
Thus, dark matter constitutes 85% of total mass, while dark energy plus dark matter constitute 95% of total mass–energy content. Because dark matter has not yet been observed directly, if it exists, it must barely interact with ordinary baryonic matter and radiation, except through gravity.
Answer:
All objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.
Explanation:
Newton's Second Law, if I remember right.
Sample a is an acid. Ex. Acid rain
Sample b is very weak acid , almost neutral ex. Milk.
