Why do pin sinks in water class 9? A body floats in water if its density is less than that of water. As the density of iron is more than that of water, an iron pin sinks in water. As the density of wood is less than that of water, it floats in water. What […]
Does a longer string have more tension?
Does a longer string have more tension? The lengths of the strings do not affect the tension. Question about tension in strings with different lengths and angles. What angle do you use in the work equation? Several incline angles are typically used; yet, the force is always applied parallel to the incline. The displacement of […]
How do you calculate the magnification?
How do you calculate the magnification? Magnification = scale bar image divided by actual scale bar length (written on the scale bar). What is magnification and its formula? The formula of magnification represents the ratio of the height of the image to the ratio of the height of the object. Furthermore, the letter ‘m’ denotes […]
What makes an equation have one solution?
What makes an equation have one solution? A system of linear equations has one solution when the graphs intersect at a point. No solution. A system of linear equations has no solution when the graphs are parallel. How do I know if an equation has infinite solutions? If we end up with the same term […]
What is a normal eye Cannot see clearly?
What is a normal eye Cannot see clearly? Explanation. A normal eye cannot see clearly the objects that are placed closer than 25cm because the power of accommodation of the eye is 25cm which is exhausted. When the maximum accommodation of the eye is reached, the ciliary muscles of the eye lens cannot become thicker. […]
Can I put a 60 watt bulb in a 100 watt socket?
What evidence supports a Conservation Law 6 co2?
What evidence supports a Conservation Law 6 co2? Answer: The evidence that supports the conservation law is that Carbon dioxide becomes glucose and oxygen during photosynthesis. The law of conservation of mass states that in a chemical reaction, mass is neither created nor destroyed. How is mass and energy conserved during photosynthesis? The AMOUNT of […]
Where is the thermosphere located?
Where is the thermosphere located? The thermosphere is a layer of Earth’s atmosphere. The thermosphere is directly above the mesosphere and below the exosphere. It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above our planet. How does the thermosphere protect us? These layers protect our […]
Is there a limit to the strength of an electromagnet?
Is there a limit to the strength of an electromagnet? There is no firmly-established fundamental limit on magnetic field strength, although exotic things start to happen at very high magnetic field strengths. Magnetic fields could get strong enough to create black holes. Does the size of a nail affect the strength of an electromagnet? Ferromagnetic […]
Can a live specimen be used in a light microscope?
Can a live specimen be used in a light microscope? Live or Dead specimen may be seen. Only Dead or Dried specimens are seen. Condenser, Objective and eye piece lenses are made up of glasses. All lenses are electromagnetic. What is the advantage of a light microscope? One big advantage of light microscopes is the […]
