When a device is used in a circuit in which the voltage is 81V? When a device is used in circuit in which the voltage is 81V , current flowing the device is 3A . The resistance is 27 ohm. V = IR ; 81 = 3 R ; R = 81/ 3 = 27. […]
What is the difference between synoptic and prognostic charts?
What is the difference between synoptic and prognostic charts? 2. How are prognostic charts different from synoptic weather maps? ď‚·Prognostic charts are computer generated forecast showing the expected pressure pattern at a specific future time. Synoptic weather maps describe the state of the atmosphere over a large area at a given moment. What is good […]
What is a Type D fire?
What is a Type D fire? Class D. Class D fires involve combustible metals, such as magnesium, titanium, and sodium. Extinguishers with a D rating are designed to extinguish fires involving combustible metals. Note: Common extinguishing agents may react with a combustible metal fire causing the severity of the fire to increase. What is a […]
What happens when an atom gains or loses an electron quizlet?
What happens when an atom gains or loses an electron quizlet? When an atom loses an electron, it loses a negative charge and becomes a positive ion. When an atom gains an electron it gains a negative charge and becomes a negative ion. What kind of bond is formed when two atoms share an electron? […]
What is CP and CV for water?
What is CP and CV for water? Specific heat is the energy required to raise the temperature of a unit mass of a substance by one degree. In thermodynamics, there are two kinds of specific heats: Cv (specific heat at constant volume) and Cp (specific heat at constant pressure). What is CP and CV? The […]
What is special about summer solstice?
What is special about summer solstice? The day that the Earth’s North Pole is tilted closest to the sun is called the summer solstice. This is the longest day (most daylight hours) of the year for people living in the northern hemisphere. It is also the day that the Sun reaches its highest point in […]
What is a critical point of a substance?
What is a critical point of a substance? Critical point, in physics, the set of conditions under which a liquid and its vapour become identical (see phase diagram). For each substance, the conditions defining the critical point are the critical temperature, the critical pressure, and the critical density. What happens to water at its critical […]
What is chemical energy for kid?
