On the medieval world-maps it was represented only the part of the world known as the 'old world', which is consisted of Europe, Asia and Africa. Before the big discoveries, people living in this continents had knowledge only of this part of the world, while South and North America, Australia and Antarctica where still unknown to them, thus they are missing in the world-maps of this period.

11. A stream in a bedrock valley located 5000 feet above ultimate base level that is draining a mountainous region in the headwa
notsponge [240]

Answer:

A stream in a bedrock valley located 5000 feet above ultimate base level that is draining a mountainous region in the headwater of a stream system would have a _____.

high gradient, and a narrow and shallow channel with no floodplain

Explanation:

A bedrock valley has no alluvium mantling the bedrock over which it flows. Alluvium (consists of sand, gravel, silt, clay, and gravel, as well as other organic matters) mantlings or coverings are usually developed in the lower part of the river with the formation of floodplains and deltas.  They may also be deposited at lakes or river banks.  Headwater streams deliver nutrients and other organic materials (e.g. fallen leaves) to downstream regions to sustain downstream aquatic life.

A basket has a mass of 5.5 kg. Find the magnitude of the normal force if the basket is at rest on a ramp inclined above the hori
Ivenika [448]
The free body diagram consists of:

1) Weight force, which is a vertical arrow downward

2) A Normal force that is perpendicular to the ramp.

The Normal force can be decomposed in a vertical component and an horizontal component.

The vertical component, Ny,  must equal the weight force, due to equilibrium (rest) condiition =>

Ny = weight = m*g = 5.5kg*9.8m/s^2 = 53.9 N

By geometry the vertical component of the Normal force, Ny is such that

cos (angle) = N / Ny => N = Ny * cos(angle)

=> N = 53.9N * cos(angle)

Now use that equation for each option:

a) 0 ° => N = 53.9N * cos(0) = 53.9N

b) 12° => N = 53.9 * cos(12) = 52.7N

c) 25° => N = 53.9 * cos(25) = 48.9N

d) 45° => N = 53.9 * cos(45) = 38.1N
