Throughout history‚ the United States and the U.S.S.R. have been competing in what is known as the "Space Race". This all began when the Russians sent the first satellite into space in 1958 called Sputnik. Soon after‚ Americans did the same. The U.S. followed in the footsteps of the U.S.S.R. with sending animals into space. When they sent the first human into space‚ Yuriy Gagaran‚ it became evident that the race to the moon had begun. In 1963‚ President John F. Kennedy made a speech saying "We

Weather and Atmospheric Water Humidity- the amount of water in the air in a particular spot. Relative Humidity- the percentage of water vapor a certain volume of air is holding relative to the max amt it can contain. 80% humidity means that it is holding 80% of the total amt of water that it can hold at that temp. Heat Index- shows what the temperature feels like due to humidity. Dew Point- the point at which air becomes saturated with water. Water will condense from the air as dew‚ if the

Analysis: 1. Explain why blood pressure and heart rate differ when measured in a reclining position and in a standing position. When a person stands‚ the heart must pump blood against the pull of gravity to reach important areas such as your brain. Veins must work hard to get blood back to your heart. As a person reclines‚ the heart does not have to pump as hard to reach the same areas‚ decreasing the blood pressure. Also‚ a person is usually more relaxed in a reclining position‚ which

Why loft insulation is needed? Loft insulation is the most cost-effective energy efficiency measure that can be installed. It can reduce heating costs up to 20%. The purpose of them is to hold the heat below within the property‚ reducing heat loss to the roof void and outside but also reducing the amount of heating needed to maintain the property at an ideal temperature. With insulation‚ the property will be warmer‚ more comfortable and it will cost less to heat. How loft insulation reduces

THERMOREGULATION IN THE NEONATE By: Shubhada Ponkshe [pic] INTRODUCTION: Thermoregulation is a critical physiologic function that is closely related to the transition and survival of the infant. An understanding of transitional events and the physiologic adaptations that neonates must make is essential to helping the nurse provide an appropriate environment and help infants maintain thermal stability. Optimizing the thermal environment has proven significant for improving the

Benjamin franklin was elected to represent the Pennsylvania at the constitutional convection which ratified the new U.S. constitution.

water molecules to rotate and become excited. This excitation causes friction in all of the molecules in the food‚ and thus‚ heat‚ which is used to cook the food. This process differs from that of a conventional oven‚ which uses heat transfer via convection‚ rather than electromagnetic waves‚ to cook food. In addition to this technology‚ microwave ovens implement a feature called a “defroster‚” whose purpose is to cook frozen foods more effectively. The defroster works by heating the food on the

Is Our Atmosphere Unique? The planet Jupiter has the biggest atmosphere in our solar system. Jupiter’s atmosphere is composed of 90% hydrogen and 9.9% helium and .1% other gases such as sulfur‚ methane‚ ammonia‚ and water vapor. It is able to hold its atmosphere in because of its massive gravitational pull that is around 2.5 times stronger than earth’s pull. To put that into perspective‚ if you weigh 100 pounds on earth you would weigh 250 pounds on Jupiter. The atmospheric layers are the
