Why is my turtle suddenly not eating? Temperature. Since turtles require their environments to be a certain temperature, if your aquarium is not warm enough this can dampen his appetite. Like many reptiles, a turtle should have areas of his tank with different temperatures that he can move about in as he pleases. How long […]

Why is longitude 180 degrees? As we move East-West, we change through 360 degrees. As we move North-South, we change through 180 degrees. In other words, going from the North Pole to the South Pole is 180 degrees. These spherical coordinates (latitude and longitude) indicate locations on a 3-dimensional representation of the Earth. What are […]

Which effect did Reconquista have? The Reconquista had the ultimate effect of driving Muslims out of the Iberian Peninsula, and contributed to the unification of a single Spanish kingdom. Which two religions were affected by the Reconquista? The Siege of Toledo was a key moment in the struggle between the Christians and Muslims in the […]

How much does it cost to build a house in Southampton? It’s tough to say with land because people could pay any number per square foot for land, but to build, a general rule of thumb is about $400 per square foot. That’s hard cost, site work and soft costs. How much does it cost […]

Does copper have high density? That is because copper has a higher density than aluminium. Density is the mass per unit volume of a substance. Density is the mass in kg of 1 m3 of the material. For copper ρ = 8940 ( kg m-3). How do you find the density of copper? You can […]

Why is the middle class getting poorer? The middle classes are getting squeezed particularly hard by the rising costs of education, health care and housing. Real, disposable incomes for the middle class have not grown since the middle of last decade, while incomes for the top 10% are hitting new highs, the OECD calculates. What […]

What is cell tag? Cell tags are used to find single cells or classes of cells. For example, all title cells could be given the tag Title, and all cells related to a particular subject could be given a cell tag identifying that subject. What is a row cell? A cell is the intersection of […]

Why is e Cell 0 in a concentration cell? Concentration cells consist of anode and cathode compartments that are identical except for the concentrations of the reactant. Because ΔG = 0 at equilibrium, the measured potential of a concentration cell is zero at equilibrium (the concentrations are equal). What happens when Ecell is 0? If […]

What is an atomic site? Atomic sites are sites (?,Jat) equipped with the atomic topology Jat. The corresponding sheaf toposes Sh(?,Jat) are precisely the atomic Grothendieck toposes. Why vacancies are equilibrium defects? Why are vacancies referred to as equilibrium thermodynamic defects? Formation of a vacancy leads to ‘missing bonds’ and distortion of the lattice. Hence, […]

What is the current in a 100w bulb connected to a 120v source? 0.833 amperes What is the current in a 60w bulb connected to a 120v source? The 120-Watt bulb has the lower resistance; and using Ohm’s law, one would expect it also has the higher current. In fact, the 120-Watt bulb would have […]
