Who invented the electricity we use today? Benjamin Franklin What is the application of electricity in our daily life? Electricity is an essential part of modern life and important to the U.S. economy. People use electricity for lighting, heating, cooling, and refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems. What is […]
How dangerous is the asteroid belt?
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 […]
Which of the following are examples of mitigation?
Which of the following are examples of mitigation? Other examples of mitigation measures include: Hazard mapping. Adoption and enforcement of land use and zoning practices. Implementing and enforcing building codes. Flood plain mapping. Reinforced tornado safe rooms. Burying of electrical cables to prevent ice build-up. Raising of homes in flood-prone areas. What are the priorities […]
What is the magnitude of the horizontal component of the velocity?
What is the magnitude of the horizontal component of the velocity? The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a […]
Which of the following property of a charge can change when it moves freely in a uniform perpendicular magnetic field?
Which of the following property of a charge can change when it moves freely in a uniform perpendicular magnetic field? The magnetic force acts perpendicular to the direction of motion of the proton. It does not change its mass and speed but changes its direction of motion. So both velocity and momentum get changed. What […]
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 […]
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? […]
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 […]
