What is correlation in rock layers? Correlation is the technique of piecing together information from widely separated rock outcrops in order to create an accurate chronological profile of an entire geologic time period. In order to accomplish this, geologists attempt to measure the absolute ages of rock strata using techniques such… Why are some rock […]
Is Starlink 5G?
Is Starlink 5G? The 5G signal beams into your home and then a wifi router blankets your space with wireless internet. Starlink has just 10,000 customers at the moment, although that number might jump rapidly because SpaceX recently opened up preorders for its satellite internet service.

How can you tell how fast someone is driving?
How can you tell how fast someone is driving? Divide the distance by the time to find the speed. The distance over the time will give you the object’s speed. In our example, 100 miles/2 hours = 50 miles/hour (about 80 kilometers/hour). How many feet in one second will a vehicle travel if the speed […]
What is the fundamental period of the following discrete time signal?
What is the fundamental period of the following discrete time signal? Therefore, a discrete-time sinusoid is periodic if its radian frequency Ω is a rational multiple of π. Otherwise, the discrete-time sinusoid is non-periodic. The fundamental period is 12 which corresponds to k = 1 envelope cycles. What is the time period of the signal? […]

Is gymnastics harder than figure skating?
Is gymnastics harder than figure skating? Gymnastics is popular for its back flips, but skating is renowned for its turns. Gymnastics needs more versatility, so guess what? Getting back up after slipping on the cold, rough ice hurts. Gymnastics, in my experience, needs more natural ability, while figure skating requires more practise. Is figure skating […]

There are pathological reasons some people set fires, but while you might hear the word “pyromaniac” thrown around lightly, there is a difference between those who are literally pyromaniacs — whose motivation is to obtain pleasure from watching fires burn — and those in most firefighter arson cases. Are firefighters more likely […]
Is air always compressible?
Is air always compressible? For low subsonic flow (less than about Mach 0.3), we usually treat air as being incompressible. It greatly simplifies the math and does not cause much error. But air is definitely compressible. No real fluid is incompressible. Is compressed air flammable? Keep in mind that canned air, those small cans of […]
Why is reducing carbon footprint difficult?
Why is reducing carbon footprint difficult? Firstly, lower than expected demand for a commodity results in lower prices making a further reduction in demand more difficult. Resulting low coal prices led to increasing demand (be it not as high as initially expected) and an increase in the market share of coal in the global primary […]
Are all adult diapers the same?
Are all adult diapers the same? When the subject of incontinence products comes up, some people are confused by the terms “adult diaper” and “pull-up underwear.” They are not the same; in fact, they are very different from one another. Adult diapers are not gender-specific and they range in size from small up to bariatric […]
