Marina CMI [18]3 years ago
4 0

Answer:

impulse=force x time

force=mass x acceleration due to gravity

force=

impulse =3000 x 2.5= ( sorry i don't have a calculator right now so you must calculate this yourself)

I converted from kg to g because it is the standard.

(1)

Troposphere – This is the densest layer and where weather events occur

Stratosphere – This is where the ozone layer is found. Some high altitude aircraft cruise in this layer.

Mesosphere – Temperatures drop with altitude in this layer

Thermosphere – This is where most of the meteorites that enter the earth’s atmosphere burn up. This layer takes up most of the Uv and X-rays from the sun. Most satellites orbiting earth are in this layer

Exosphere – almost akin to space due to the thinness of the layer. Molecules in the layer often escape into space

(2)

A ‘pause’ is a transition between the above-mentioned distinct layers. The tropopause, for example, occurs between the troposphere and the stratosphere and the stratopause between the stratosphere and mesosphere and thermopause is found between thermosphere and exosphere.

(3)

A temperature inversion is a rise in temperatures with altitude in a layer in the atmosphere. One layer exhibiting temperature inversion is the stratosphere. This is due to the ozone layer that absorbs UV light. The upper ozone absorbs most of the UV light, than lower ozone, exciting the molecules and making the higher altitudes in the layer to be warmer.

(4)

The ozone layer protects life on earth from the high energy UV radiation from the sun. UV is capable of causing double-stranded break on DNA resulting in genetic mutations on organisms. Most of these would be lethal. The Ozone absorbs most of the UV before it reaches earth's surface. Ozone is formed when an oxygen molecule reacts with another oxygen atom to form an O₃. The oxygen atoms are made from the splitting of an oxygen molecule by UV light.

Lorico [155]

Answer:

Independent - Water/Type of water (salt and pure)

Dependent - Height of plant

Controlled - Amount of water

Explanation:

Independent is what the experimenter manipulates (in this case being the type of water.)

Dependent is what the experimenter measures and is a result of the independent (in this case being the height of plant)

Controlled is what you are trying to keep the same (in this case the amount of water you give each plant.)
