Is the inside of a battery dangerous? Battery leakage (commonly known as battery acid) is nasty, corrosive stuff – it can burn your skin, contaminate soil, and of course ruin whatever device it has leaked into. For lead batteries, sulfuric acid is the dangerous residue, which requires a different type of clean-up. What is inside […]
Is it safe to zipline?
Is it safe to zipline? Researchers at Ohio State University found that almost 12 percent of zip-line injuries resulted in fractures or other injuries requiring hospitalization, making zip-lining mishaps at least as serious as rock climbing. Has anyone died on a zipline? There have been fatal zip-line crashes in the U.S., including two in Utah, […]
Is there a natural law?
Is there a natural law? Natural law holds that there are universal moral standards that are inherent in humankind throughout all time, and these standards should form the basis of a just society. Human beings are not taught natural law per se, but rather we “discover” it by consistently making choices for good instead of […]
What property of exoplanets will affect the amount of wobble that is detected?
What property of exoplanets will affect the amount of wobble that is detected? We all know that the chains of gravity shackle a planet to its star. That star’s enormous gravitational influence keeps its planetary family in orbit. But gravity works both ways: as the planets sweep around in their orbits, they tug on their […]
What is the direction of velocity in circular motion?
What is the direction of velocity in circular motion? We will see that unlike linear motion, where velocity and acceleration are directed along the line of motion, in circular motion the direction of velocity is always tangent to the circle. This means that as the object moves in a circle, the direction of the velocity […]
What are the symptoms of too much calcium in your blood?
What are the symptoms of too much calcium in your blood? What are the symptoms of a high calcium level? Loss of appetite. Nausea and vomiting. Constipation and abdominal (belly) pain. The need to drink more fluids and urinate more. Tiredness, weakness, or muscle pain. Confusion, disorientation, and difficulty thinking. Headaches. Depression. What foods to […]
What does tidal heating cause?
What does tidal heating cause? The more the tidal force changes, the more the moon stretches, and the more it heats. This heat causes activity like volcanoes and geysers and can keep water liquid to form oceans. Why is tidal heating important? Tidal heating is responsible for the geologic activity of the most volcanically active […]
What is the formula for relative speed?
Is electricity and magnetism the same?
Is electricity and magnetism the same? 3) Electricity and magnetism are essentially two aspects of the same thing, because a changing electric field creates a magnetic field, and a changing magnetic field creates an electric field. (This is why physicists usually refer to “electromagnetism” or “electromagnetic” forces together, rather than separately.) How can we prevent […]
What is a DNA code?
What is a DNA code? The DNA code contains instructions needed to make the proteins and molecules essential for our growth, development and health. The cell reads the DNA code in groups of three bases. Each triplet of bases, also called a codon, specifies which amino acid? will be added next during protein synthesis. What […]
