Answer:

Explanation:

The change in past ice age climates can be explained by using Milankovitch cycle. According to the cycle past ice can be caused by any of the these reasons:

  1. Earth's orbit around the sun.
  2. Obliquity of the axis.
  3. Eccentricity of it's orbit.
  4. Precedence of earth's orbit.

However, today materials from past are being used such as rocks, fossil remain,etc. to study the earth's climate.

A snowball starting at rest rolls down a hill and reaches 5 m/s. If the hill is
Lostsunrise [7]

Answer:

The acceleration of the snowball is 0.3125

Explanation:

The initial speed of the snowball up the hill, u = 0

The speed the snowball reaches, v = 5 m/s

The length of the hill, s = 40 m

The equation of motion of the snowball given the above parameters is therefore;

v² = u² + 2·a·s

Where;

a = The acceleration of the snowball

Plugging in the values, we have;

5² = 0² + 2 × a × 40

∴ 2 ×  40 × a  = 5² = 25

80 × a = 25

a = 25/80 = 5/16

a = The acceleration of the snowball = 5/16 m/s².

The acceleration of the snowball = 5/16 m/s² = 0.3125 m/s² .
