What is the difference between qualitative and quantitative example? Quantitative data is fixed and “universal,” while qualitative data is subjective and dynamic. For example, if something weighs 20 kilograms, that can be considered an objective fact. However, two people may have very different qualitative accounts of how they experience a particular event. What are the […]
How do stars create energy?
How do stars create energy? Stars produce energy from nuclear reactions, primarily the fusion of hydrogen to form helium. These and other processes in stars have lead to the formation of all the other elements. Do we need the stars? As for their purpose, stars are vital for life to exist. As we know, the […]
What is a star that gives off regular bursts of energy called?
What is a star that gives off regular bursts of energy called? Pulsars are rotating neutron stars observed to have pulses of radiation at very regular intervals that typically range from milliseconds to seconds. Pulsars have very strong magnetic fields which funnel jets of particles out along the two magnetic poles. These accelerated particles produce […]
Why is oil used in Thiele tube?
Why is oil used in Thiele tube? Oil is poured into the tube, and then the “handle” is heated, either by a small flame or some other heating element. The shape of the Thiele tube allows for formation of convection currents in the oil when it is heated. These currents maintain a fairly uniform temperature […]
What type of person was Dr Percy Julian?

In the 1930s chemists recognized the structural similarity of a large group of natural substances—the steroids. What are […]
How much water do Established plants need?
How much water do Established plants need? Water deeply as needed. During prolonged periods of dry weather water once or twice per week. Generally, it takes plants at least two years to fully develop a sustaining root system. Properly planted and watered plants should be fairly well established, and can thrive with less watering than […]
What does the One angstrom Microscope allow scientists to see?
What does the One angstrom Microscope allow scientists to see? Achieving Sub-Angstrom Resolutions One angstrom is equivalent to 0.1 nanometers. In general, atomic bonds measure 1 to 2 angstroms in length. Any resolution below 1 angstrom should allow experts to see individual atoms. In electron microscopes, the resolution depends mostly on the aperture of the […]
