Why is it better to recycle Aluminium than to extract it? Recycling aluminium uses 95% less energy than producing aluminium from raw materials. It also saves 97% of green house gas emissions produced in the primary production process. It is 100 per cent recyclable, for ever, so carbon savings increase every time it passes through […]
What are the similarities and differences between the human eye and a camera?
What are the similarities and differences between the human eye and a camera? There are many similarities between the human eye and a camera, including: a diaphragm to control the amount of light that gets through to the lens. This is the shutter in a camera, and the pupil, at the center of the iris, […]
How much does an average textbook weight in kg?

Weight and mass are not interchangeable terms….Mass of a Physics Textbook. Physics Textbook Weight (lbs) Mass (kg) Conceptual Physics (Addison-Wesley, 1987) 2.7 lbs 1.23 […]
Is error a parallax?
Is error a parallax? Measurements made by viewing the position of some marker relative to something to be measured are subject to parallax error if the marker is some distance away from the object of measurement and not viewed from the correct position. How do you calculate Parsec? In terms of the small angle formula, […]
What does the brain do as soon as it receives information?
What does the brain do as soon as it receives information? Answer. When an organ perceive stimulus,The impulse sent to the brain by the sensory neurons,the brain process the information and sends a response through the motor neurons to organs,muscles and glands. What part of the brain remembers names? Blame the left side of your […]
Does axial tilt affect climate?
Does axial tilt affect climate? The greater Earth’s axial tilt angle, the more extreme our seasons are, as each hemisphere receives more solar radiation during its summer, when the hemisphere is tilted toward the Sun, and less during winter, when it is tilted away. Why is axial tilt important? The tilt of the Earth’s spin […]
When a substance is cooled it usually expands?
When a substance is cooled it usually expands? Most matter expands when heated and contracts when cooled, a principle called thermal expansion. The average kinetic energy of the particles increases when matter is heated and this increase in motion increases the average distance between its atoms. What happens to barometric pressure when temperature increases? Air […]
Why do slime molds have so many sexes?
Why do slime molds have so many sexes? The Facts of Life These spores develop into sex cells. In slime molds, it’s three genes, matA, matB, and matC (all of which contain variants) that are responsible for determining sex. A mature individual has two copies of every gene and is capable of producing 8 types […]
Which is correct Schrodinger time dependent equation?
Which is correct Schrodinger time dependent equation? Hence ψn(x)exp(−iEnt/ℏ) satisfies the equation. the probability does not change in time and for this reason, ψn(x) is called a stationary state. In such a state, the energy remains fixed at the well-defined value En. Why are eigenvalues important? Eigenvalues and eigenvectors allow us to “reduce” a linear […]
What is carbon-13 called?
What is carbon-13 called? Isotopes of carbon. Complete table of nuclides. Carbon-13 (13C) is a natural, stable isotope of carbon with a nucleus containing six protons and seven neutrons. As one of the environmental isotopes, it makes up about 1.1% of all natural carbon on Earth. What causes carbon to enter the soil? Carbon moves […]
