Natural Science short answers - Essay Example

Task: Natural Science Short Answers Some home-run sluggers prefer heavy bats, claiming that the extra weight in the collision results in a longer hit. Other players choose a light or moderate weight bat with a similar claim (occasionally, when a wood bat is used, a player will illegally install a cork to lessen the weight). Who is correct in this argument about weight? Explain.The sluggers who prefer heavier bats are correct. Lighter bats are easier and faster to swing however, they have less inertia.

A ball from a corked bat comes out with less velocity meaning a shorter hit. A heavier bat will hit the ball harder than a lighter corked bat and a ball hit by a heavier bat will go farther. So, corking in this case will not result in longer hits, but it may allow a batter to have more solid hits on the ball.2. Suppose in a restaurant your coffee is served about 5 or 10 minutes before you are ready for it. In order that it be as hot as possible when you drink it, should you pour in the room-temperature cream right away or when you are ready to drink the coffee?

Explain You should pour the room temperature cream right away. Black coffee is a better radiation and will cool faster. When you add the room temperature cream, you lighten the coffee minimizing the chances of losing heat. Using Boltzmann’s law that says hotter surfaces radiate heat faster on adding the cream you also reduce the rate at which it will lose heat. Finally, when you add cream the coffee becomes more viscous resulting in a slower heat loss3. Read the last question at the end of this article- Why Do We Still Have Big Questions: http://archive.wired.com/wired/archive/15.

02/bigquestions.html?pg=3 and then ask your own question about physics or chemistry.Quiz: Is the earth round or flat?Photos from space attest that the earth is round. But there are other conflicting theories that suggest otherwise. Greek scholars suggested that the earth was round; however, Isaac Newton first suggested that the earth was not really round. Earth’s shape also changes over time due menagerie of other vibrant factors. So, is the Earth round or flat?4. Explain why this cartoon is funny.

The stars and the universe keep going on and on and they look such a spectacular sight to behold. But man considers himself a big deal, but then he has to stay inside with his all of his appliances. It’s funny because if man was a big deal as he considers himself will also be out there with his appliances instead of staying indoors.
