Does anything have 100 efficiency? A system can never be 100% efficient. The reason behind this is because of heat and sound energy are lost in some amount in every system. No matter they are waste or not. So a system doesn’t exist, with 100% efficiency. Is human body energy efficient? Alas, our bodies are […]
What are the 3 level of awareness?
What are the 3 level of awareness? The three levels of awareness in human consciousness which are divided by Freud: the conscious, preconscious, and unconscious. Each of these levels interferes and overlaps with Freud’s ideas of the id, ego, and superego. What are 4 levels of consciousness? Take a look at the four levels of […]
What are two bad things about plate tectonics?
What are two bad things about plate tectonics? Two bad things that can happen as a result of plate tectonics are: volcanoes and earthquakes. What is the implication of being near a plate boundary? If we choose to live near convergent plate boundaries, we can build buildings that can resist earthquakes, and we can evacuate […]
What is the difference between a pelican and a puffin crossing?
What is the difference between a pelican and a puffin crossing? Puffin. Crossings differ from Pelican crossings, as they do not have a flashing green man/flashing amber signal. This layout encourages pedestrians waiting at the crossing to look at the approaching traffic at the same time as looking at the red man/green man signal. Who […]
How do you write 78000 in scientific notation?
How do you write 78000 in scientific notation? To write 78,000 in scientific notation: 70, 000 = 7×10. 7.8×104 (Note that 78,000 is a whole number, so we dropped the zeros) How do you write 0.002 in scientific notation? Therefore, the decimal number 0.002 written in scientific notation is 2 × 10-3 and it has […]
Does acceleration due to gravity depend on mass?
Does acceleration due to gravity depend on mass? The acceleration due to gravity does not depend on the mass of the object falling, but the force it feels, and thus the object’s weight, does. Why does mass resist acceleration? The more mass an object has the more weight it will have. Weight is caused by […]
How do I make my bestie miss me?
How do I make my bestie miss me? Understand the squabbles and disputes among groups of young people are common. Stop talking so much when you are with your friends. Don’t be too touchy-feely.

Is gold a good heat reflector?
Is gold a good heat reflector? Surfaces designed to reflect a broad spectrum of electro-magentic waves, (shiny things generally, like mirrors or polished metal) specifically infrared wavelengths are good reflectors of radiant heat. Gold is the best material for reflecting radiant heat. Does gold Harden work? Heat: In general, Yellow Gold can be hardened by […]
What is the formula for acceleration using distance and time?
What is the formula for acceleration using distance and time? Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes […]
What are the two basic types of speedometer?
What are the two basic types of speedometer? There are two types of speedometers: electronic and mechanical. Because the electronic speedometer is actually a relatively new invention — the first all-electronic speedometer didn’t appear until 1993 — this article will focus primarily on the mechanical speedometer, or the eddy-current speedometer. What do numbers symbolize on […]
