What is natural frequency and resonance? The natural frequency is the frequency at which an object will remain vibrating after hitting it. What happens when you excite that object at the same frequency as its natural frequency? Well, that is resonance. What is the difference between frequency and fundamental frequency? The fundamental frequency is just […]
Can Insulators be charged by contact?
Can Insulators be charged by contact? 3 Answers. When you charge an insulator by friction, the close contact of two electron clouds (each from a different medium) allows for electrons to be transferred between them. The number of atoms coming in contact to each other by friction is proportional to the area of the two […]
What is the hardest metal to drill through?
What is the hardest metal to drill through? Cobalt (HSCO) is considered an upgrade from HSS because it includes 5-8% Cobalt blended into the base material. This is a great option for drilling into harder steel as well as stainless steel grades. Carbide (Carb) is the hardest and most brittle of the drill bit materials. […]
What happens during refraction?
What happens during refraction? Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. The wavelength decreases as the light enters the medium and the light wave changes […]

Why is the White-eyed characteristic more common in males?
Why is the White-eyed characteristic more common in males? Because the white-eye allele is recessive, a female will have white eyes only if she has the white-eye allele on both her X chromosomes. However, in males, a single copy of the white-eye allele on the lone X chromosome will lead to white eyes because no […]
