Is it OK to run 10K everyday? Running 10K (or even about 5 miles) daily would be an excellent exercise regime, although one should really take a day or two off per week for recovery. Running has no risk factors with respect to health to speak of, although one should talk about exercise, fitness, and […]

What is a 1% slope? 1% as a decimal is 0.01 and hence the slope is 0.01. That means for a run of pipe of a certain length the rise must be 0.01 times the length. Thus for you example, since the length of the run is 80 feet which is 80 × 12 = […]

What animal has the highest terminal velocity? blue whale Will an ant die if you drop it off a building? Okay, so here’s the conclusion I’ve reached: no, the ants won’t die. And they won’t explode when they get to the top, either. “A rat is killed, a man is broken, a horse splashes.” Many […]

What is a slow reaction rate? The rate of a reaction is the speed at which a chemical reaction happens. If a reaction has a low rate, that means the molecules combine at a slower speed than a reaction with a high rate. The reaction will happen faster which means the rate of that reaction […]

How do giant stars die? All stars eventually run out of their hydrogen gas fuel and die. When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant. While most stars quietly fade away, the supergiants destroy themselves in a huge explosion, called a supernova. How much does a […]

What are two disadvantages of using a radio telescope? Limitations of radio telescopes The radio waves received on Earth are very weak and of low intensity. The intensity of an electromagnetic wave is the energy it delivers per second. Radio waves have low frequencies and long wavelengths resulting in low energy photons. Is 4K worth […]
