What are three ways to induce a current in a circuit? Explain three ways of inducing current in a coil Inducing current on a coil by moving the coil in a magnetic field. Inducing current on a coil by by changing the magnetic field across it. By taking two cunductiong coils and insert them over […]

Why do light rays bend when they travel from air to glass? When light rays travel from air into glass or from air into water, it bends towards normal. This is because the speed of light rays decrease while travelling from air into glass or water. When light rays travel from glass into air or […]

Is the nervous system the first thing to develop? The fetal nervous system — i.e., your baby’s brain and spinal cord — is one of the very first systems to develop. In fact, it’s making big strides before you even know you’re pregnant. What is the beginning of the nervous system called? neural plate How […]

Is it OK to close glass doors on fireplace? Glass doors should be fully open when starting a fire and when the fire is burning strongly. The glass doors should be closed as the fire dies down to minimize the amount of room air going up the fireplace chimney. When burning gas logs in a […]

Can a 30 lb bow kill a deer? bow. With the right arrow and broadhead combo 30 lbs is plenty to kill a deer. I’ve never seen a big game animal shot with a 30 pound bow but my son shot a deer with his 40 pound bow at 25 yards and got a complete […]

What are the five characteristics of organisms? Properties of Life. All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life. What is a one celled organism called? A unicellular organism, also […]

What are the different types of boundary conditions? How can we do better? Types of Boundary Conditions. Dirichlet Boundary Condition. Neumann Boundary Condition. Robin Boundary Condition. Mixed Boundary Condition. Cauchy Boundary Condition. Applications. Structural and Solid mechanics. How do you define boundary conditions? Boundary condition is defined such that the velocity on the walls is […]

What does dark matter do to humans? But more-massive pieces of dark matter known as macroscopic dark matter, or macros, could lurk in the cosmos. In theory, macros could directly interact with physical objects such as human bodies, causing “significant damage,” according to the new study titled “Death by Dark Matter.” Will dark energy run […]

How much hotter does humidity make it feel? If the temperature outside is 75° F (23.8° C), humidity can make it feel warmer or cooler. A relative humidity of 0% would make it feel like it’s only 69° F (20.5° C). On the other hand, a relative humidity of 100% would make it feel like […]

Which rock layer is the oldest? bottom layer What are the reasons why layers of rocks are formed? Layered rocks form when particles settle from water or air. Steno’s Law of Original Horizontality states that most sediments, when originally formed, were laid down horizontally. However, many layered rocks are no longer horizontal. What are the […]
