How dangerous is the asteroid belt? The danger lies not in the risk of hitting a large object. The number of objects in the asteroid belt increases steeply with decreasing size, but even at micrometer sizes the Pioneer spacecraft were hit only a few times during their passage. That is not to say that asteroids […]
What does neutrino mean?
What does neutrino mean? A neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero. Neutrinos are one of the most abundant particles in the universe. Because they have very little interaction with matter, however, they are incredibly […]
What force acting on an area of 0.5 m2 will produce a pressure of 500 Pa?
What units are used for W?
What is 3D triangle called?
What is 3D triangle called? In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. How do you identify 3D shapes? In geometry, a three-dimensional shape can be defined as a solid figure or an object […]
Can I reverse a transformer?
Can I reverse a transformer? When a transformer is reverse fed, the taps move to the output side and so their operation is reversed. For reverse fed applications, raising the taps will increase output voltage and lowering the taps will lower output voltage. What is the difference between step up transformer and step down transformer? […]

Why do hurricanes never hit California?
Why do hurricanes never hit California? In short, wind direction and cold water are the main reasons we don’t see hurricanes in California. Tropical storms and tropical storms that become hurricanes need warm water to form. The area of 15 degrees north latitude is prime real estate for storms over open water. Is a hurricane […]
What is the wavelength of the first harmonic?
What is the wavelength of the first harmonic? For the first harmonic, the length of the string is equivalent to one-half of a wavelength. If the string is 1.2 meters long, then one-half of a wavelength is 1.2 meters long. The full wavelength is 2.4 meters long. What is a harmonic wave? A harmonic is […]
