Answer:
1)X(t)=Xo±Vo(t)±*a
2)a(t)=
Explanation:
1)with this formula you can determine the position of the object studied when you have an accelerated, or deaccelerated motion, where Xo its your beginning position, and Vo is your beginning speed, and t is the difference of time between the final time and the initial time. The signs of the equation (+ or -) depends if its displacement its increasing on time, or diminishing, it means : positive speed, and acceleration, and in the oposite case negative speed and acceleration respectively.
2)this formula lets you know the variation of speed at each time (considering its constant), so if you have a constant variation of speed along a determined time, then you can use it.
This formula is used in uniformly accelerated rectilinear motion

Answer:Ice that formed thousands of years ago is often found to contain tiny bubbles of gas. This gas came from the ATMOSPHERE.
Explanation:
Atmospheric gases which consists of carbondioxide, nitrogen oxides and rare gases can be trapped inside the water body as bubbles. If these bubbles are surrounded by ice when they form, they get trapped and remain in the ice cube. A typical example of ice that contains bubbles of gases includes glacier ice. These are mass of ice that moves slowly over the land. It preserve bits of atmosphere from thousands of years ago in tiny air bubbles, or, deeper within the core, trapped within the ice itself. This is one way scientists know that there have been several Ice Ages.
