What are 3 properties of a piece of paper? The most important optical properties of paper are brightness, colour, opacity, and gloss. The term brightness has come to mean the degree to which white or near-white papers and paperboard reflect the light of the blue end of the spectrum (i.e., their reflectance). What are two […]
What are the goals of social research?
What are the goals of social research? Ideas help social researchers make sense of evidence, and researchers use evidence to extend, revise and test ideas.” Social research thus attempts to create or validate theories through data collection and data analysis, and its goal is exploration, description, explanation, and prediction. How do you understand objectivity in […]
What is the similarities between climate and weather?
What is the similarities between climate and weather? Weather is the combination of temperature, humidity, precipitation, cloudiness, visibility, and wind. In popular usage, climate represents the synthesis of weather; more formally, it is the weather of a locality averaged over some period (usually 30 years), plus statistics of weather extremes. What are 5 differences between […]
When the total charge in a capacitor is doubled?
When the total charge in a capacitor is doubled? C is constant, so if Q doubles, V also has to double, hence energy is quadrupled. When two or more capacitors are connected in series to a battery? When capacitors are connected in series, the total capacitance is less than any one of the series capacitors’ […]
Will dark mode save battery on LCD?
Will dark mode save battery on LCD? Dark mode can save battery, but only if your device has an OLED screen. Phones, computers, and other devices with LCD screens won’t save battery with dark mode on. Does LCD display consume more power? In fact in newer liquid-crystal display, or LCD, monitors white is actually slightly […]
What are the three types of thermal energy transfer?
What are the three types of thermal energy transfer? Heat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact. Convection is the movement of heat by a fluid such as water or air. Radiation is the transfer […]
What is antibody in simple words?
What is antibody in simple words? An antibody is a protein produced by the body’s immune system when it detects harmful substances, called antigens. Examples of antigens include microorganisms (bacteria, fungi, parasites, and viruses) and chemicals. Each type of antibody is unique and defends the body against one specific type of antigen. How antibodies work […]
How do dogs act when they smell cancer?
How do dogs act when they smell cancer? Dr. Stenzel notes that in case studies, dogs persistently sniffed, licked and nipped at melanoma lesions on their owners’ skin, even through clothing, prompting the owners to identify the cancerous sites and seek care from clinicians. Can dogs smell death coming? Probably not. However, due to their […]
What causes a voltage change from a transformer primary to its secondary?
What causes a voltage change from a transformer primary to its secondary? When current is reduced, the magnetic field strength reduces. When the magnetic lines of flux flow around the core, they pass through the turns of the secondary winding, causing a voltage to be induced into the secondary coil. What is the principle of […]
What does a cliff look like?
What does a cliff look like? A cliff is a mass of rock that rises very high and is almost vertical, or straight up-and-down. Cliffs are very common landscape features. They can form near the ocean (sea cliffs), high in mountains, or as the walls of canyons and valleys. Waterfalls tumble over cliffs. How do […]
