What is explosion in class 8? CBSE NCERT Notes Class 8 Chemistry Combustion and Flame. The type of combustion reaction that occurs with the evolution of tremendous amount of heat, light, gases and sound is known as Explosion. For instance, when we burn a cracker it bursts with the liberation of tremendous amount of heat, […]
Why do water bottles have an air hole?
Is viscosity dependent on temperature?
Is viscosity dependent on temperature? According to the kinetic theory of gases, viscosity should be proportional to the square root of the absolute temperature, in practice, it increases more rapidly. With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same. Does salt increase surface tension? Yes, adding […]
What if the boy and the girl pull the heavy crate at the same time?
What are 3 benefits of biodiversity?
What are 3 benefits of biodiversity? Increase ecosystem productivity; each species in an ecosystem has a specific niche—a role to play. Support a larger number of plant species and, therefore, a greater variety of crops. Protect freshwater resources. Promote soils formation and protection. How do humans benefit from biodiversity? Biodiversity plays a crucial role in […]
How do you zero a triple beam balance?
How do you zero a triple beam balance? The triple beam balance is used to measure masses very precisely; the reading error is 0.05 gram. With the pan empty, move the three sliders on the three beams to their leftmost positions, so that the balance reads zero. What is the uncertainty of the triple beam […]
How do you control speed and torque of a DC motor?
How do you control speed and torque of a DC motor? Torque Control Torque can be controlled directly by controlling the armature current. Fig. In Fig. 10.8a, a phase-controlled rectifier, in combination with a dc-link filter inductor, can be used to create a variable dc-link current which can be applied directly to the armature terminals […]
What is tissue and function?
What is tissue and function? Tissue is a group of cells that have similar structure and that function together as a unit. Primary types of body tissues include epithelial, connective, muscular, and nervous tissues. Epithelial tissues form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in […]
How do variables affect the result of the research study?
How do variables affect the result of the research study? The key to designing any experiment is to look at what research variables could affect the outcome. The independent variable is the core of the experiment and is isolated and manipulated by the researcher. The dependent variable is the measurable outcome of this manipulation, the […]
What does the slope of the best fit line represent?
What does the slope of the best fit line represent? The Line of Best Fit Equation and Its Components The coefficient of each independent variable represents the degree of change in y for each additional unit in that variable. In a simple regression with one independent variable, that coefficient is the slope of the line […]
