At what distance should an object be placed from a convex lens of focal length 12 cm to obtain an image of 24 cm from it what will be the magnification produced in this case? Solution. T the object should be placed at a distance of 72 cm from the lens. How far should an […]
What is the name of functional unit?
What is the name of functional unit? Cells are called the structural and functional unit of life because all the living organisms are made up of cells and also all the functions taking place inside the body of organisms are performed by cells. What is the simplest structural and functional unit of living things? The […]
What Colour is potassium iodide?
What Colour is potassium iodide? white How can I make potassium iodide at home? Potassium iodide (KI) is prepared by reacting iodine with a hot solution of potassium hydroxide. It is mainly used in the form of a saturated solution, 100 g of potassium iodide to 100 ml of water. This equates to approximately 50 […]
Can we remove carbon from the atmosphere?
Can we remove carbon from the atmosphere? Photosynthesis removes carbon dioxide naturally — and trees are especially good at storing carbon removed from the atmosphere by photosynthesis. How do we get rid of carbon dioxide from the body? Carbon dioxide is made in our bodies as cells do their jobs. The lungs and respiratory system […]
What are the five types of air masses?
What are the five types of air masses? Five air masses affect the United States during the course of a typical year: continental polar, continental arctic, continental tropical, maritime polar, and maritime tropical. Continental air masses are characterized by dry air near the surface while maritime air masses are moist. What is an example of […]
Are cosmic rays dangerous to humans?
Are cosmic rays dangerous to humans? Cosmic ray collisions in the body can be harmful because they can damage the DNA in cells. Remember, a single cosmic ray has a large amount of energy. If it collides with DNA, it will destroy part of that DNA strand. Why are cosmic rays so dangerous? Solar proton […]
What is load of a motor?
What white blood cells are involved in the inflammatory response?
What white blood cells are involved in the inflammatory response? Neutrophils, which target microorganisms in the body, can also damage host cells and tissues [74]. Neutrophils are key mediators of the inflammatory response, and program antigen presenting cells to activate T cells and release localized factors to attract monocytes and dendritic cells [7]. How do […]
Why the voltage coil is connected in parallel with the armature coil?
Why the voltage coil is connected in parallel with the armature coil? Because the armature windings and field windings of a DC shunt motor are connected in parallel, the current in a shunt motor is split into two parts—current through the armature and current through the field windings—and total current is the sum of the […]
At which temperature does all molecular motion steps?
At which temperature does all molecular motion steps? All molecular motion stops at 0 degrees Kelvin or -273.15 degrees Celsius. The temperature at which all molecular motion ceases is known as… What is the difference between molecular motion and temperature? the relationship between molecular motion and kinetic energy is that the faster the molcules are […]
