Answer:>
Explanation:
All ionic compounds have high melting and boiling points
The answer is "C" because the equator is closest to the sun, because the sun's rays hits the earth surface at the higher angel at the equator and also the sun is directly overhead the equator.
<span>why is your formula x=? if i'm reading it right the formula is the height of the object at time t.
That being the case, set your setup (which looks right) equal to 0 and solve for t.
This will tell you how long it takes to hit the ground.
Plug this value of t into the forumla -9.8t+2.8 and that will tell you the speed at time t.</span>
Every particle of mass is attracted to every other particle of mass. The magnitude of the force between two objects is proportional to the product of their masses, and inversely proportional to the square of the distance between them. The direction of the force is along the line between their centers.
(NOTE: Newton's 3rd law of motion tells us that gravitational forces always come in pairs. Between two objects, there are two forces ... one in each direction. Their strengths are equal ... Your weight on Earth is exactly equal to the Earth's weight on YOU.)
Answer:
Equal
Explanation:
The law of conservation of energy states that the total momentum before and after a collision are equal
