Is human eye better than camera? Most current digital cameras have 5-20 megapixels, which is often cited as falling far short of our own visual system. This is based on the fact that at 20/20 vision, the human eye is able to resolve the equivalent of a 52 megapixel camera (assuming a 60° angle of […]

Is it bad to always park on a hill? Answer: Any time you park a car with an automatic transmission on a steep hill or incline, you are running a risk of transmission damage if you don’t exercise a lot of care. The problem can be avoided by setting your parking brake on steep hills […]

What is the difference between structural and ball and stick model? A molecular formula uses chemical symbols and subscripts to indicate the exact numbers of different atoms in a molecule or compound. A structural formula indicates the bonding arrangement of the atoms in the molecule. Ball-and-stick and space-filling models show the geometric arrangement of atoms […]

What will happen if two forces act on an object? If two forces act on an object in the same direction, the net force is equal to the sum of the two forces. This always results in a stronger force than either of the individual forces alone. What do we call it when two or […]

How do you find the buoyant force of a balloon? Buoyant Force of Balloons The formula for buoyant force is: (B) = ρ V g. ρ = Density of Fluid (We used density of the air because the balloons were afloat, not submerged) V = Displaced Volume. g = 9.8 (gravity) Density of air(ρ)= 1.225 […]

How does electricity flow in a circuit draw an open circuit? The electric circuit in which there is a gap in the connections between the terminals of the cell, wires and the bulb, etc is called an open circuit (or incomplete circuit).

What is produced when aluminum reacts with hydrochloric acid? Aluminum metal reacts with hydrochloric acid to form hydrogen gas and an aluminum chloride solution. In this investigation, you will predict the mass of hydrogen gas produced by a given amount of reactants, then measure the amount, and compare them. Hydrochloric acid is an aqueous solution […]
