What are the two main goals of epidemiology? The objectives of epidemiology include the following: to identify the etiology or cause of disease. to determine the extent of disease. to study the progression of disease. What are the two goals of epidemiology? The principal aim of epidemiology is to identify factors related to the occurrence […]
What is the difference between mechanical energy and total energy?
What is the difference between mechanical energy and total energy? The total energy consists of all forms of energy present in the system and the system is an isolated system. Mechanical energy is equal to sum of kinetic energy and potential energy. Does total energy remain constant? The total amount of energy and matter in […]
What are the types of interference in communication?
What are the types of interference in communication? The common types of interference in cellular networks are: self-interference, multiple access interference, co-channel interference (CCI) and adjacent channel interference (ACI). Self-interference is induced by signals that are transmitted on a shared transmitter. What is interference in Bluetooth? The Problem. To communicate between your devices, Bluetooth sends […]
What are the two types of transistors?
What are the three energy systems?
What are the three energy systems? There are 3 Energy Systems: Anaerobic Alactic (ATP-CP) Energy System (High Intensity – Short Duration/Bursts) Anaerobic Lactic (Glycolytic) Energy System (High to Medium Intensity – Uptempo) Aerobic Energy System (Low Intensity – Long Duration – Endurance) Which energy system is the quickest? phosphagen system Which energy system is fastest […]
What triggers mass wasting?
What triggers mass wasting? Mass-wasting events often have a trigger: something changes that cause a landslide to occur at a specific time. It could be rapid snowmelt, intense rainfall, earthquake shaking, volcanic eruption, storm waves, rapid-stream erosion, or human activities, such as grading a new road. How can the effects of mass wasting be reduced? […]
What are the similarities and differences between conduction convection and radiation?
What are the similarities and differences between conduction convection and radiation? In conduction, heat transfer takes place between objects by direct contact. In convection, the heat transfer takes within the fluid. In radiation, heat transfer occurs through electromagnetic waves without involving particles. The heat transfer takes place due to the difference in temperature. Is cotton […]
How many WH is a 18650?
What is the third ionization of aluminum?
What is the third ionization of aluminum? On the other hand, aluminium has three electrons located on its outermost energy level, one located in a 3p-orbital and two in the 3s-orbital. The third ionization energy is the energy needed to remove a third electron from an atom. What is the third ionization energy of Al? […]
What is a surface tension in chemistry?
What is a surface tension in chemistry? Surface tension is a fundamental property of the surface of liquid. Surface tension is responsible for the curvature of the surfaces of air and liquids. Surface tension is responsible for the ability of some solid objects to “float” on the surface of a liquid. What are the types […]
