What is the distance from a concave mirror of focal length 25 cm? Answer Expert Verified We can Says that ,if object is Equal to image , For which that distance will be double to it’s focal Length. Therefore, the object Distance should be 50 Cm from the pole of the mirror. Where are periscopes […]

What is crust explain? “Crust” describes the outermost shell of a terrestrial planet. Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. […]

What solution has 36 grams in 100 mL solvent at 25 C? sodium chloride What would you predict is the solubility of potassium nitrate at a temperature of 5 C? Check your 5 °C prediction with the Gizmo. 5 °C predicted solubility: 155 °C actual solubility: 16.8695 °C predicted solubility: 225 (Impossible to find actual […]

Can the amount the balloon fills up be controlled by the amount of vinegar or baking soda? Can the amount the balloon fills-up be controlled by the amount of vinegar or baking soda? Yes, if you don’t use the right amount of vinegar or baking soda the balloon will not inflate, if you use too […]

What is the critical approach to technology? Drawing inspiration from Marx’s approach, critical theory of technology argues that technology is both rational and biased. The design, development and eventual implementation of a technology are seen as normative processes through which interests and values are delegated to technological devices and systems. Does technology determine society? Technological […]

How can I check my oxygen level at home iPhone? On your iPhone, open the Health app. Follow the onscreen steps. If you don’t see a prompt to set up, tap the Browse tab, then tap Respiratory > Blood Oxygen > Set up Blood Oxygen. After you complete setup, open the Blood Oxygen app on […]

What makes it easier to push heavy things answer? Answer: When you push there is one component of force that adds to the weight of the body and hence there is more friction. When you pull the vertical component of force is against the weight of body and hence there is less overall friction. So […]

Is work done and kinetic energy Same? In other words, the work done is equal to the change in K.E. of the object! This is the Work-Energy theorem or the relation between Kinetic energy and Work done. In other words, the work done on an object is the change in its kinetic energy. W = […]

What is the thinnest liquid? Thanks to the “super material” graphene, a team of researchers managed to create one of the world’s thinnest layers of liquid. There’s now a new understanding of the word “wet” thanks to physicists who created the thinnest film of liquid ever. What is a viscous sauce? A sauce that runs […]

What is the full form of laser? Light amplification by stimulated emission of radiation What are the uses of laser technology? Lasers are widely used for laser material processing in manufacturing, e.g. for cutting, drilling, welding, cladding, soldering (brazing), hardening, surface treatment, marking, engraving, micromachining, pulsed laser deposition, lithography, etc. What is Laser What are […]
