Which number is used in forced convection? The parameter of importance in forced convection is the Péclet number, which is the ratio of advection (movement by currents) and diffusion (movement from high to low concentrations) of heat. When the Peclet number is much greater than unity (1), advection dominates diffusion. What is the primary driving […]
How are the circuits wires in houses?
How are the circuits wires in houses? Circuits in houses are generally wired in parallel, which allows you to operate each light or power point independently of the others. How many circuits should a house have? Fifty years ago, a kitchen might have been served by a single electrical circuit, but today, a newly installed […]
What does listening to 528 Hz do?
What does listening to 528 Hz do? According to the current study, sound waves with 528 Hz frequency in 100 dB intensity induce testosterone production in brain by enhancing StAR and SF-1 and reducing P450 aromatase gene expression. Frequency of 528 Hz also reduces total concentration of reactive oxidative species in brain tissue. How many […]
Is angular velocity affected by radius?
Is angular velocity affected by radius? Linear/tangential velocity, in a circlular path, increases with the increase in radius and decreases with the decrease in radius. Hence, the angular velocity remains the same no matter what the change in radius is(W=V/r). Why is angular momentum always conserved? Objects can change their shape and still conserve angular […]
Is there a weight limit for private pilots?
Is there a weight limit for private pilots? In the US there’s no specific weight limit in the regulations. Instead, they just say that you must be capable of performing the duties of a pilot, e.g. 14 CFR 61.113: A very heavy pilot may be too heavy to fly in some smaller aircraft (including training […]
What is the weight of a human kidney?
What is the 5 era?
What is the 5 era? The book divides the timeline of the universe into five eras: the primordial Era, the Stelliferous Era, the Degenerate Era, the Black Hole Era and the Dark Era. In addition to explaining current cosmological theory, the authors speculate on what kinds of life might exist in future eras of the […]

What is one action a person can take to help ensure ability to participate in physical activity throughout life Apply sunscreen at steadily exercise regularly use tobacco? In this context, one action that helps ensure you can participate in physical activity throughout life is exercise regularly because in this way you can develop basic abilities […]
Should you do easy or hard homework first?
Should you do easy or hard homework first? If you are easily frustrated and are quick to feel overwhelmed when things get tough, then perhaps you’re the type of person who should tackle the small, quick homework assignments first. In school, start your afternoons by completing the easiest assignments: doing so will motivate you to […]
What materials are transparent to radio waves?
What materials are transparent to radio waves? RF transparent materials are materials where RF fields can penetrate with no heating happen. So far, I know some like Teflon, PPL, PVC, and ABS. They are made of plastics and have almost 0 dielectric loss factor. Is Fiberglass transparent to radio waves? An excellent insulator, fiberglass has […]
