For the fifth day of Blogmas, I will be discussing the physics of singing Christmas carols. When someone is singing, they emit sound waves. Because sound waves are mechanical waves, they are required to travel through a medium. When traveling through this medium, the particles vibrate creating a frequency which is measured in vibrations per second or hertz. In turn, the higher the frequency, the higher the pitch of the singer. The loudness or quietness of the singer is measured by the amplitude
For the fifth day of Blogmas, I will discuss a specific scene in the movie Home Alone. At one point in the movie, two burglars enter the house because they believe nobody is home. Little do they know Kevin is still home and ready to protect himself. At one point, he swings a paint bucket and it hits one of the burglars. I thought it would be interesting to calculate the length of the string the paint bucket is attached to using the equation T=2π+(L/g)^(1/2). The period of the paint bucket is 4s
I have always been fascinated by the idea of skydiving, so I thought it would be interesting to learn the physics behind it. When a person skydives, they are accelerating downward do to the force of gravity. Simultaneously, the amount of air resistance increases as the faster the skydiver falls. Once the force of air resistance is as large as the force of gravity, the skydiver no longer accelerates because the force of gravity equals air resistance. This equality is known as terminal velocity. T
For the first day of blogmas I decided it would be interesting to calculate how many reindeer it would take to carry Santa's load of toys. First, I found that there are approximately 2 billion children in the world (people under the age of 18). The average reindeer can pull about 136 kg and we can assume that children receive an average of 5kgs worth of gifts. Using this information, if can be found that Santa will need approximately 73.5 million reindeer to help him deliver his presents.
For day 3 of Blogmas, we are going to discuss the physics of Christmas lights. It is important to find Christmas lights wired in parallel because the set of lights will still work if one light blows. This way you will not go through the struggle of hanging all of your lights just for fail when you turn them on.Lights that do not work when one bulb breaks are wired in series. In series , electricity must flow from one bulb to the next. In a parallel, each light is on its own circuit to the power
