What is the tiny tube in the thermometer called? The liquid-in-glass thermometer is a well-known temperature-measuring instrument that is used in a wide range of applications. The fluid used is normally either mercury or colored alcohol, and this is contained within a bulb and capillary tube, as shown in Figure 14.18(a). What does narrow inner […]
Why are variables important in research study?
Why are variables important in research study? Dependent and independent variables are important because they drive the research process. Dependent and independent variables are also important because they determine the cause and effects in research. How important is it for the researcher to identify the type of variable used in the study? Answer: It is […]
Is physics the hardest science?
Is physics the hardest science? A-Level Physics is considered as one of the hardest courses due to the amount and complexity of material as well as the difficulty of exam questions. Even though, the subject is quite interesting and compelling for many of the students. How old are 12th graders? Stamford American International School Grade […]
How much is 100 km in miles per hour?
Does Sun have shadow?
Does Sun have shadow? Technically, like any non-transparent object, the Sun would cast a shadow on another object. So theoretically, it does cast a shadow, practically it would only do so if a brighter star (or other source of light) were to appear or move near it. What is a shadow give an example? Shadow […]
What do you mean by oxidation give examples?
What do you mean by oxidation give examples? The term oxidation was originally used to describe reactions in which an element combines with oxygen. Example: The reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium. In the course of this reaction, each magnesium atom loses two electrons to form […]
Which has more visibility fog or mist?
What are the 3 main sections of a turbine engine?
What are the 3 main sections of a turbine engine? (1) The cold section includes the engine inlet, compressor, and turbine sections. (2) The hot section includes the combustor, diffuser, and exhaust sections. What are the four types of turbine engine combustors? The type of engine is further classified by the path the air takes […]
Is carbon 14 a radioisotope?
Is carbon 14 a radioisotope? Carbon-14 (14C), or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Carbon-12 and carbon-13 are both stable, while carbon-14 is unstable and has a half-life of 5,730 ± 40 years. Carbon-14 decays into nitrogen-14 through beta decay. What do we use […]
Is copper a solenoid?
Is copper a solenoid? An electromagnet is a coil of wire with an electric current flowing through it. When the wire is coiled around in a cylinder, we call this a solenoid. Copper is used because it has a low electrical resistance (see conducting properties). This means that it is easy for the current to […]
