If the de Broglie wavelength of an electron is 380 nm,what is the speed of this electron? (melectron = 9.11 × 10-31 kg,h = 6.626 × 10-34 J ∙ s)
Contact Area
The surface or region where two objects meet or press against each other, often critical for the transfer of force or heat.
Duo-servo Brakes
A type of drum brake system where each shoe acts as a servo to the other, enhancing braking efficiency, commonly found in heavier vehicles.
Self-energizing
Refers to a mechanism in brake systems where the brake shoes are designed to use the motion of the vehicle to increase the force applied to the drum, enhancing braking efficiency.
Non-servo Type Brake
A brake system where the shoes do not use the rotation of the drum to self-apply, resulting in a simpler design often used in rear brakes.
