Is a yoyo a weapon? It is rumored that it was used as a weapon for hunting game or other land animals. The yo-yos was actually first made by the Duncan yo-yo demonstrators in the 1930s and the yo-yo today is now considered a weapon due to the Duncan brothers making up the rumor of […]
How many groups are on the central atom?
Which type of magma is most explosive form of magma?
Which type of magma is most explosive form of magma? andesitic Which three factors affect the formation of magma? What three factors affect the formation of magma? Pressure, water, and temperature. What are the factors that affect the melting of magma? The factors that mainly affect in the formation of magma can be summarized into […]
How do you calculate percent uncertainty in resistance?
How do you calculate percent uncertainty in resistance? The rule to calculate errors says that: When two quantities are multiplied or divided, the relative error is the sum of the relative errors in the individual quantities. So the uncertainty in resistance is 7%. What is the uncertainty of a resistor? Using the maximum values for […]
Why Rbcl has high boiling point?
Why Rbcl has high boiling point? Covalent character – More covalent character results in less melting and boiling points as it becomes easy to break the dominating Vander waal’s forces but for compounds with more ionic nature the electrostatic force of attraction dominates which is difficult to break and hence results in higher melting and […]

Increase in working population, e.g. through immigration, higher birth rate. Increase in labour productivity, through better education and training or improved technology. What are the consequences of […]
Who debunked heliocentrism?
Who debunked heliocentrism? Today virtually every child grows up learning that the earth orbits the sun. But four centuries ago, the idea of a heliocentric solar system was so controversial that the Catholic Church classified it as a heresy, and warned the Italian astronomer Galileo Galilei to abandon it. How Copernicus change the society? When […]
What is gravitational potential energy write its formula?
What is gravitational potential energy write its formula? The change in gravitational potential energy, ΔPEg, is ΔPEg = mgh, with h being the increase in height and g the acceleration due to gravity. The gravitational potential energy of an object near Earth’s surface is due to its position in the mass-Earth system. How do you […]
What is the value of resistance R?
What is the value of resistance R? The actual value of resistance R shown in the figure is 20Ω. This is measured is an experiment as shown using the standard formula R=VI, where V and I are the readings of the voltmeter and ammeter respectively. What is the value of resistance in an open circuit? […]
What is the condition for second order of Spectra?
What is the condition for second order of Spectra? When the pathlength difference is two wavelengths, another bright image occurs (the second order diffraction maximum). If light of a longer wavelength is used, the maxima are at larger angles. When light of multiple wavelengths is used, the different wavelengths(different colors) are separated. How many orders […]
