Answer:
Aluminum
Explanation:
The density of Aluminum is 2.7 g/cm3
We know the volume and mass of the unknown metal, as density is mass/volume: 81g/30cm3 = 2.7 g/cm3 which is the density of Aluminum :)
Sperm, Egg (1 egg and 3 polar bodies), 4 different, haploid
Answer:
Yes.
Explanation:
Energy can always be transformed from one form to another form.
E.g. Throw a ball in upward direction ,so it will have some kinetic energy due to its mass and velocity. At some height ball will stop and will start coming down.
Answer:
It would certainly make a difference.
Explanation:
The mass of a planet determines how thick the planets atmosphere would be, if it can even sustain an atmosphere. If all the masses are the same, all of the large planets would not be able to sustain life, while all of the smaller, denser planets still have a chance.
The mass of a planet also affects it’s gravitational pull. If all of the planets had the same mass, they would all have the same gravitational pull, meaning that they would all attract the same amount of asteroids, meteors, and other spacial objects.
Overall, the simulation would certainly be different, for many, many reasons. The above are only two, and if you would like more, just add a comment and I can give you more.
Climate change cannot be
measured with a single instruments but require thousands of measuring devices
that spread across the globe, land and under the sea. Thus,parameters
measured in climate change includes: Rainfall, Sunshine hours, Temperature, Relative
humidity, Atmospheric pressure, Wind speed .
However, there are various instruments used for the measuring of climate
change and they can be classified as follows: weather balloons and buoys, thermometers, wind anemometers,
Manual rain gauges, transmitting rainfall gauges and Automatic Weather
Stations
