The speed of the Earth’s rotation changes as you go North or South away from theequator. Finally, when you reach one of the Earth’s poles, you’re taking a whole day to just turn once in place – that’s not very fast. Because you’re spinning around and around on the Earth, t...
If a car moves 60 miles per hour, by how many times as fast per hour does a surface on the Earth's equator move due to Earth's rotation? Kinematics: The study about the variation in the particle's motion with position and...
When the airspeed reached about 17 mph (27 kph), I could feel the hang glider lift me off the ground. As I was lifted, I moved my hands from the sides of the control bar to either side of its base. To fly, I had to do two things: maintain a constant speed and keep my ...
1,100 mph Turbos utilize exhaust gases to power a turbine wheel, which is connected via a shaft to a compressor wheel. As the two wheels turn, large amounts of ambient air are sucked in and compressed. This air is passed through a charge-air cooler to further increase its density b...
In spite of all this weight, it can reach up to 90 mph. In the next section, we will look at the equipment inside the TIV. The Future of the TIV and Why Not Just Use a Tank? The current Tornado Intercept Vehicle is really a prototype, and it has undergone a number of ...
What speed gives you the best gas mileage? There isn’t a specific speed that guarantees better gas mileage; however, it’s important to note that fuel consumption increases once your car exceeds 60 mph. At higher speeds, your car needs to deal with wind resistance and rolling resistance, ...
Another component to your weight loss week is one that many people tend to overlook:Staying hydrated. In fact, people who have obesity are more likely to be improperly hydrated (while those without obesity are more likely to be more hydrated), according to a July 2016 study in the Annal...
Many experts, includingFrederick Reichheld, refer to NPS as “The one number you need to grow.” Here is the formula to calculate NPS score: You can also calculate the percentage of promoters and detractors separately and deduct the latter from the former to get your NPS score. ...
The downward flow of the water into the drain begins to rotate, and as the rotation speeds up, a vortex forms. Why does the water start rotating? There are many explanations, but here's one way to think about it: Imagine yourself as a particle in the water, suddenly pulled toward the...
