What element is shiny ductile and conducts heat well? Metals What type of elements are poor conductors of heat and electricity? Nonmetals are poor conductors of heat and electricity, because electrons are not free to move. Nonmetals are found to the right of the stair-step line, except for hydrogen which is in group 1. Group […]
How do you calculate light?
How do you calculate light? Determine the Needed Lumens A lumen is a unit measurement of light. To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. How many lights […]

How do birds stay in the air?
How do birds stay in the air? Flapping: When birds flap, the stroke of their downbeat moves the wing tips forward and downward. And as they move forward, the rush of air on their airfoil wings causes more lift. But because flapping birds have smaller wings than soaring birds, they must move forward faster to […]

What are 2 types of thermal energy?
What are 2 types of thermal energy? The three types of thermal energy transfer are conduction, convection and radiation. Conduction involves direct contact of atoms, convection involves the movement of warm particles and radiation involves the movement of electromagnetic waves. What will happen to Earth if there is no source of heat? Without the Sun’s […]
What is the hijack code?
What is the hijack code? The distress code of 7500, sent through an electronic device called a transponder, signals a hijacking or unlawful interference. This communication, called squawking, is done silently so that the hijacker remains unaware, thereby creating an advantage for pilots. Which aircraft has the right of way over all other traffic?
