Explanation of Solution

Introduction:

The Earth was formed nearly 4.5 billionyears ago from the solar system. All the swirling gases and dust were pulled by gravity to form the earth.

Before 2.4 billion years ago the oxygenstarted to appear initially. After the significant oxygen formation in earth's atmosphere, first life of the earth was appeared.Thenearliest plant living on the land took came into existence. Around 200 million years ago,earliest mammals and dinosaurs appeared. Then dinosaurs mass extinction took place. Then earliest human appeared.

Conclusion:

Thus, the correct sequence is,

  1. First time there is significant oxygen in Earth's atmosphere.
  2. First life on earth
  3. Earliest plants living on land.
  4. Earliest animals.
  5. Earliest mammals.
  6. Impact causes extinction of dinosaurs.
  7. Earliest human.

2. A projectile is shot from a launcher at an angle 0,, with an initial velocity magnitude vo, from a point even with a tabletop. The projectile hits an apple atop a child's noggin (see Figure 1). The apple is a height y above the tabletop, and a horizontal distance x from the launcher. Set this up as a formal problem, and solve for x. That is, determine an expression for x in terms of only v₁, 0, y and g. Actually, this is quite a long expression. So, if you want, you can determine an expression for x in terms of v., 0., and time t, and determine another expression for timet (in terms of v., 0.,y and g) that you will solve and then substitute the value of t into the expression for x. Your final equation(s) will be called Equation 3 (and Equation 4).
