Earth science is made of many branches of knowledge concerning all aspects of the Earth system. The main branches are geology, meteorology, climatology, oceanography, and environmental science. Astronomy uses principles understood from Earth to learn about the solar system, galaxy, and universe.

<h3>Overview of Earth Science:</h3>

Only recently have humans begun to understand the complexity of our planet Earth. We have only known for a few hundred years that Earth is just a tiny part of an enormous galaxy, which in turn is a tiny part of an even greater universe.

An important component of experiments is the different variables involved. A variable is any parameter in the experiment that can change. This could be a parameter like temperature, weight or height, or it could be more complex, such as life expectancy or growth rate. Depending on how you set up your experiment, you will use different kinds of variables. There are three basic types to be familiar with.

<h3>Independent variable:</h3>

The first type is the independent variable. This is the variable that is manipulated during an experiment. For example, when experimenting with how fertilisers affects plant growth, the fertiliser is the independent variable because this is the variable that you change. It might help to think of the independent variable as the cause of change in the experiment.

<h3>Dependent variable:</h3>

In contrast to this, the dependent variable is the variable that is affected during an experiment. In our experiment, our dependent variable would be plant growth since this is affected by the amount of fertiliser applied. If you think of the independent variable as the cause, then the dependent variable is the effect.

For a moving object, the force is acting on the object varies directly with the object’s acceleration. When a force of 9 N acts
svetlana [45]

Answer:

12 Newtons

Step-by-step explanation:

We can use Newton’s Second Law to find the mass first.

F = ma

9 = 3m

mass = 3

Substitute this into the second equation.

F = ma

F = 3(4)

F = 12N

Hope this helps! :D

Animals and people that take in more energy than they expend will get fatter. Here are data on 12 rhesus monkeys: 6 lean monkeys
In-s [12.5K]

Answer:

mean lean body mass of the lean monkeys = 8.4kg

mean lean body mass of the obese monkeys = 10.4kg

Step-by-step explanation:

a) Mean = Sum of Body mass/number of body mass

For lean monkeys, mean = (6+7.5+9.2+9.7+9.1+9.1)/6

Mean = 50.6/6

Mean = 8.4

b)

for obese monkeys, mean = (8+9.1+10.3+12+11.9+11.2)/6

Mean = 62.5/6

Mean = 10.4
