Does masturbation affect immunity? An orgasm may benefit your immune system Though the study was very small, the researchers found that masturbation increased the number of inflammatory mediators called leukocytes (white blood cells) and natural killer cells. Both of these fight infection as a part of the body’s immune response. How can you tell if […]

Is Q A joule or kilojoule? You want your q to be in units of Joules or kJ. If you used the q=mC(delta T) with your given C, your q would be in units of (grams)(kJ). In the problem, you were given the heat capacity, not the specific heat capacity. Therefore, you don’t need mass […]

What are the advantages and disadvantages of Mendeleev classification? When noble gases were discovered can be kept in a separate group without disturbing the existing order. Disadvantages: He couldn’t allocate a correct position to hydrogen. Atomic masses didn’t increase in a regular manner, so it was impossible to predict how many elements could be discovered […]

What is the DC voltage symbol? Direct Current Voltage (DCV): Sometimes it will be denoted with a V– instead. This setting is used to measure direct current (DC) voltage in things like batteries. Alternating Current Voltage (ACV): Sometimes it will be denoted with a V~ instead. How do I measure DC voltage without a multimeter? […]

What are the 3 basic types of scaffolds in the construction industry? Workers who use scaffolds can be divided into three groups: Suspended Scaffolds. Supported Scaffolds. Aerial Lifts. What is the narrowest scaffolding? Narrowest 600mm scaffold tower For our narrowest tower try the stair tower. It comes in a 600mm wide frame so it can […]

What is a pulley system in physics? Pulleys are mechanisms compost by wheel and rope used to lift heavy objects onto tall heights. They change the direction of an applied force and they can even reduce the force needed to lift a weight. Pulleys systems are common used in constructions. What is the tension formula? […]

Is a protozoa a virus? Diseases that are caused by viruses include the common cold, influenza, herpes, yellow fever, shingles, rabies, polio, and mononucleosis. Protozoa are single celled organisms. Most protozoa do not cause infections, but a few do. Malaria, dysentery, African sleeping sickness are caused by different species of protozoa. How can you distinguish […]
