Can I use a different group size battery? Member. Any battery will work as long as it has the minimum Cold Cranking Amps needed for your car and will physically fit in your battery tray. If it’s too big for the tray you can always mount it in the trunk. QFT. Does a bigger battery […]

What part of the electromagnetic spectrum has the highest frequency? Gamma rays What are the similarities and differences of different waves of electromagnetic spectrum? They only differ from each other in wavelength. Wavelength is the distance between one wave crest to the next. Waves in the electromagnetic spectrum vary in size from very long radio […]

Who named the electron? G. Johnstone Stoney How did they discover the electron? In 1897, J.J. Thomson discovered the electron by experimenting with a Crookes, or cathode ray, tube. He demonstrated that cathode rays were negatively charged. In addition, he also studied positively charged particles in neon gas. What did E Goldstein discover? Eugen Goldstein […]

Why should we use nanotechnology? Nanotechnology also lowers costs, produces stronger and lighter wind turbines, improves fuel efficiency and, thanks to the thermal insulation of some nanocomponents, can save energy. The properties of some nanomaterials make them ideal for improving early diagnosis and treatment of neurodegenerative diseases or cancer. Where do we apply nanotechnology? Applications […]

How many Newtons does it take to break an egg? 25 Newtons Why is an egg so strong? So what makes the egg so strong? The answer is in the egg’s arched shape. Architects know that a three-dimensional arch is one of the strongest architectural forms around. In the same way, the eggshell’s curved shape […]

How do you convert G to CC? Conversion Table. 1 gram (g) = weight of 1 cubic centimeter (cc, cm3) of pure water at temperature 4 °C = 1000 milligrams (mg) = 0.001 kilogram (kg). 1 cubic centimeter (cc, cm3) = 1 ml (milliliter) = 0.0338140227 US fluid ounces (fl. oz) = 1/1000 L (Liter, […]

Which is the most reactive in Group 1? francium Why does boiling point increase down Group 7? The boiling and melting points increase as you go down the group. This is because the strength of the Van Der Waals forces (or induced dipole-dipole interactions) increases since the atoms have more electrons as you descend the […]

How do you tell if a math problem is a function? Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line […]

How is 9.81 calculated? In SI units, G has the value 6.67 × 10-11 Newtons kg-2 m2. The acceleration g=F/m1 due to gravity on the Earth can be calculated by substituting the mass and radii of the Earth into the above equation and hence g= 9.81 m s-2. … What is acceleration due to gravity […]

What does a 50 yard parallax mean? In a rifle scope, parallax means if the scope is held fixed on a target, and you move you head, you will see the crosshairs move on the target. It isn’t possible to be parallax-free at all ranges. Scopes are adjusted to be parallax free at one range […]
