What are the differences between local and global winds?

/in /by

Local winds blow over certain parts of the Earth, but global winds blow around the globe as the name ‘global’ suggests.

Local winds like the Sirocco, Harmattan, leveche, Nor’westers, Mistral, Chinook, Foehn can be found only in certain regions. For example, Sirocco, Harmattan, are seasonal winds blowing across Northern Africa and the Leveche blows over Southern Spain. The Chinook are warm winds flowing down the leeward side of the Rocky Mountains. The Mistral is a chilly wind which blow in the Mediterranean regions during winter.

The Trade winds, Mid Latitude Westerlies and Polar Easterlies are examples of global winds.

The Trade Winds are found between the 30 degrees S and N latitudes. There are the North-East Trades and the South-East Trades, both converging at the the Equator.

The Westerlies are a deep wind system found in the Temperate latitudes blowing from the West towards the East.

The Polar Easterlies blow from the Polar regions towards the Mid-latitudes.

0 kg mass. When the spring is not stretched, the mass is located at z = 0m. The mass is pulled to z = .1m and released.

A spring with a spring constant of 200 N/m is attached to a 2.0 kg mass. When the spring is not stretched, the mass is located at z = 0m. The mass is pulled to z = .1m and released.

a) What is the period of oscillation of the mass?

b) What is the magnitude of the velocity of the mass when it is at z = .05m?

c) What is the acceleration of the mass when it is z = .05m?

Which types of galaxies have a clearly defined disk component?

/in /by

Spiral galaxies, barred spiral galaxies, and lenticular galaxies.

If you had to pick between the main types (spiral, elliptical, and irregular), then it would be spiral. However, sometimes it is a bit more complex.

Spiral Galaxies consist of a central bulge and protruding arms. Sometimes, they have two arms that connect in a bar that crosses the center, and this is called a barred spiral galaxy. Lenticular galaxies are like a cross between spirals and ellipticals and are also disc-shaped.

Ellipticals are like big eggs or spheres, and irregular galaxies are unclear blobs. Peculiar galaxies do not fit into any of the other categories.

Here are some useful resources on galaxy types:http://space-facts.com/galaxy-types/https://en.wikipedia.org/wiki/Lenticular_galaxyhttps://en.wikipedia.org/wiki/Peculiar_galaxy

Fruit flies normally have dull red eyes, but geneticists have identified quite a few genes which cause them to have different colored eyes.

Fruit flies normally have dull red eyes, but geneticists have identified quite a few genes which cause them to have different colored eyes. The very first of these discovered was a gene with a recessive allele for white eyes. This gene isXlinked.Xlinkage works the same in fruit flies as it does in mammals. We’ll use the symbolsW(dominant red eyes) andw(recessive white eyes) for these two alleles.

  1. You mate a red eyed female fly (whose male parent had white eyes) to a male with red eyes. What are the genotypes of these two flies? Enter them on your answer sheet.
  2. Fruit flies have hundreds of offspring at a time. When you look at the offspring from this mating, what phenotypic ratio do you expect to find? Don’t forget that you are looking at the effects of anXlinked gene, and don’t forget toinclude your workin the space provided. Your ratio must, of course, be properly expressed.
