Where is the smallest muscle in the body? What’s the smallest muscle in your body? Your middle ear is home to the smallest muscle. Less than 1 millimeter long, the stapedius controls the vibration of the smallest bone in the body, the stapes, also known as the stirrup bone. What parts of your body never […]

How long does it take for the ball to hit the ground? three seconds Does it take a ball longer to go up or down? While coming down, the force of air drag is upward and the force of gravity is downward, so the ball’s downward acceleration has average magnitude less than g, say adown […]

What are two uses for sonar? Sonar uses sound waves to ‘see’ in the water. NOAA scientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and map objects on the seafloor such as shipwrecks, and map the seafloor itself. There are two types of sonar—active and passive. What is […]

Is humidity hot or cold? Humidity is the presence of water molecules in the air. High humidity levels are more likely in warm air, because it can hold more water at higher temperatures. If the air in your home is warm, it will also have the capacity to hold a lot of moisture. What is […]

What is beta decay process? Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other. In beta minus decay, a neutron decays into a proton, an electron, and an antineutrino: n Æ p + e – +. What is […]

What happens if an atom is not electrically neutral? Atoms which are not electrically neutral are called ions. One can collect electric charge by transferring electrons. Materials with an excess of electrons are negatively charged. Those with a deficiency of electrons are positively charged. What if there is no electron? You would become plasma as […]

What type of fuel can be substituted for an aircraft if the recommended octane is not available? What type fuel can be substituted for an aircraft if the recommended octane is not available? A) The next lower octane aviation gas. B) Unleaded automotive gas of the same octane rating….2.3.2.4.5.A.1. 2.3.2.4.5.A.1 PAR PRG PRH RPA RPG […]

What is the difference between a primary consumer and a secondary consumer and tertiary? The main difference between primary secondary and tertiary consumers is that primary consumers are the herbivores that feed on plants, and secondary consumers can be either carnivores, which prey on other animals, or omnivores, which feed on both animals and plants, […]

How do you calculate watts? AC three phase amps to watts calculation formula P(W) = √3 × PF × I(A) × VL-L(V) So watts are equal to square root of 3 times power factor PF times amps times volts: watt = √3 × PF × amp × volt. or. W = √3 × PF × […]

What are the two most common carbonate minerals? The two most common carbonate minerals are calcite, CaCO3 (Calcium carbonate), and dolomite, CaMg (CO3)2 (calcium/magnesium carbonate). Which of the following is the best identification of minerals? The most common physical properties are crystal form, color, hardness, cleavage, and specific gravity. One of the best ways to […]
