What does a concave lens look like?
What is one example of an unseen source exerting a force?
What is one example of an unseen source exerting a force? Unseen Sources and Receivers of Forces It is not always easy to tell what is exerting a force or what is receiving a force. For example, you cannot see what exerts the force that pulls magnets to refrigerators. You cannot see that the air […]
How do you calculate light?
How do you calculate light? Determine the Needed Lumens A lumen is a unit measurement of light. To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. How many lights […]
Which detector is used in HPLC?
Which detector is used in HPLC? HPLC Detectors UV-Vis Detectors. The SPD-20A and SPD-20AV are general-purpose UV-Vis detectors offering an exceptional level of sensitivity and stability. Refractive Index Detector. Fluorescence Detectors. Evaporative Light Scattering Detector. Conductivity Detector. What should we do first before using the HPLC instrument? Before the freshly prepare mobile phase is pumped […]
What are the 3 kinds of solubility?
What are the 3 kinds of solubility? Based on the concentration of solute dissolves in a solvent, solutes are categorized into highly soluble, sparingly soluble or insoluble. Does base increase solubility? The anion in sparingly soluble salts is often the conjugate base of a weak acid that may become protonated in solution, so the solubility […]
What is sodium-22 used for?
What is sodium-22 used for? use of sodium Of the radioactive artificial isotopes, sodium-22 (2.6-year half-life, the longest half-life of a sodium isotope) is used as a radioactive tracer for natural sodium. Sodium-24 (15-hour half-life) is limited in use by its short life and is produced by irradiation in a nuclear reactor. Is sodium-22 stable? […]
What are 2 types of thermal energy?
What are 2 types of thermal energy? The three types of thermal energy transfer are conduction, convection and radiation. Conduction involves direct contact of atoms, convection involves the movement of warm particles and radiation involves the movement of electromagnetic waves. What will happen to Earth if there is no source of heat? Without the Sun’s […]
When was the last magnetic reversal?
When was the last magnetic reversal? The reversal was dated to approximately 15 million years ago. In August 2018, researchers reported a reversal lasting only 200 years. But a 2019 paper estimated that the most recent reversal, 780,000 years ago, lasted 22,000 years. How long does it take for Earth magnetic field to reverse? about […]
How do you increase the mechanical advantage of a screw?
How do you increase the mechanical advantage of a screw? Screws move objects to a greater depth (or higher elevation) by increasing the force applied to the screw. The mechanical advantage of a screw is always greater than 1 because the output force applied by the screw is greater than the input force applied to […]
