Answer: It was known as the SPACE RACE.
Explanation: The space race was a cold war between the Soviet Union (USSR) and the United States (US), to get satellites and humans into space. The competition began in earnest on August 2, 1955, when the Soviet Union responded to the US announcement. On April 12, 1961, the USSR surprised the world again by launching Yuri Gagarin into a single orbit around the Earth in a craft they called Vostok 1.
Answer:
C. how the size of a magnet affects the strength of its magnetic pull on objects.
Explanation:
"Magnetic force" is <em>inversely proportional to distance squared. </em>This is also related to the size of a magnet. The bigger the size, the bigger the domain it occupies and the stronger the magnetic field. However, this is not often the case and it largely depends on the types of magnets.
In the situation above, Jazelle wanted to determine how her five different-sized magnet affect the strength of their magnetic pull on the paper clips. In order to do this, she tried to<em> measure the distance</em>. The<em> closer the distance</em>, the <em>higher the magnetic field</em> and the stronger the strength. The farther the distance, the<em> lower the magnetic field</em> and the <em>weaker the strength.</em>
So, this explains the answer.
When fossil fuels are burnt, CO2 is released into the air and is taken up by plants during photosynthesis to form glucose and subsequently starch.
Fossil fuels contain a large proportion of carbon atoms. When fossil fuels are burnt, these carbon atoms are released as carbon dioxide and escape to the atmosphere as atmospheric CO2 in air.
Recall that plants take up the CO2 in air during the process of photosynthesis. This CO2 becomes combined with water in the presence of sunlight to form glucose.
This glucose is converted to starch and stored in plant tissues. This is how the carbon atom inside a fossil fuel becomes a carbon atom inside a plant.
