Do you have to a Covid-19 vaccine? Yes, it does and others to help us through the epidemic and return to a better life. But wait! Once you get vaccinated, you can get another donut! At least, that’s the same alliance Krispy Kreme offers. When you receive your vaccine, you receive a donut. And it’s not just one donut – it’s one every day. That’s a lot of donuts.
Well, what about some physics comparisons to match your delicious food?
Suppose all Americans with a Covid-19 vaccine receive (and eat) once a day. Obviously, eating food gives you the energy to do things — and how food works. So, suppose all these people use that extra energy to get on the bikes. All baskets are connected by generators that plug into the electrical grid. What energy can this produce?
The first thing we need is the amount of donuts eaten per day. According to the Centers for Disease Control and Prevention, from April 7, 63 million Americans had been fully vaccinated. (Don’t worry too much about numbers – I’ll do all my math in Python to change the standards, if it pleases you. I also think all of these people receive their money every day.)
Next, I need to determine the amount of energy per donut. According to Krispy Kreme’s website, Bright light and calories 190. But what does that mean with calories? The first calorie was made to describe it changes in the power of oil on various objects. Later, people used the term to measure the amount of energy that your body can absorb from eating food. However, there is a problem: For some reason, all food labels list calories – but these are real place. So the donut has 190,000 calories. I think it just sounds like a huge number for people to think about eating.
There is another powerful component: the joule. Since this is the most powerful component for scientists, I will use it. Switching between units, 1 calorie equals 4.184 joules.
But how does this relate to your daily life? Let us consider what you can do without much effort. Suppose you had a book on the floor and you took it out to put on the table. Since you are holding the book a little farther away, you need to adjust the gravity of the book. The change in gravity is equal to the volume of the volume (approximately one kilogram) multiplied by the gravitational component (1 kg)g = 9.8 N / kg) and then multiplied by the long distance change (approximately one meter). This will give a powerful change of about 10 joules. As a result it gives you a hard feeling of the amount of energy in the joules.
What about power? Energy is the process by which electricity is converted. It tells you how to use energy efficiently. Like the equation, it looks like this:
