Do forces have direction? A force is a vector quantity. As learned in an earlier unit, a vector quantity is a quantity that has both magnitude and direction. Because a force is a vector that has a direction, it is common to represent forces using diagrams in which a force is represented by an arrow. […]
What is the distance between two contour lines called?
What is the distance between two contour lines called? The elevation difference between two adjacent contour lines is called the contour interval (CI). Usually the contour interval is noted on the map legend. In most topographic maps every 5th contour line is drawn in bold print or wider than other contours. Such lines are called […]
How do you interpret mean median and mode in research?
What are all the structures in cytoplasm?
What are all the structures in cytoplasm? It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus. All of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm. Which […]
Is plastic or wood a better insulator?
Is plastic or wood a better insulator? Metal is a good conductor of heat, while wood and plastic are good insulators. A conductor transfers thermal energy (heat) well, while an insulator does not transfer thermal energy (heat) well. What is the warmest insulation for jackets? Loftier (or puffier, if you will) materials consist of more […]
Does size affect buoyancy?
Does size affect buoyancy? Because the buoyancy of a solid cube of material depends on its density, which does not vary with the size of the object, changing the size of a cube does not affect whether it will sink or float. Do things weigh less underwater? A: When objects are placed in water, their […]
What happens when a solid is dissolved in a liquid?
What happens when a solid is dissolved in a liquid? In the simplest case it involves mixing two materials together. The most common examples of dissolving involve a solid and a liquid, usually water. When a solid dissolves the solid (solute) and the liquid (solvent) form a very close intimate mixture called a solution. Why […]
What are large scale maps give two examples?
What are large scale maps give two examples? Large scale maps : These maps represent small area of the earth on a large size of paper sheet with greater details. Examples: Cadastral maps, topographical maps….A map bearing a scale of 1: 4000 and larger is called : Cadastral map. Topographical map. Wall map. Atlas map. […]
What is the difference between control variable and independent variable?
What is the difference between control variable and independent variable? Independent variable – the variable that is altered during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment. Any change in a controlled variable would invalidate the results. What is the different types of variables? Parts of […]
Are the layers still horizontal or are they bent Why?
Are the layers still horizontal or are they bent Why? Answer. Answer: Figure 10.6: Rocks that were originally deposited in horizontal layers can subsequently deform by tectonic forces into folds and faults. Folds constitute the twists and bends in rocks. How is horizontal unconformity formed? An angular unconformity is an unconformity where horizontally parallel strata […]
