Is gold still used in medicine? Gold-based drugs have been developed and used to treat illnesses such as rheumatoid arthritis. Research is currently ongoing into the role that gold can play in cancer treatment. A method has already been developed that delivers anti-cancer drugs directly to tumours using gold nanoparticles. How do humans use gold? […]

What are three properties of mixtures?
What are three properties of mixtures? Mixtures can be classified on the basis of particle size into three different types: solutions, suspensions, and colloids. The components of a mixture retain their own physical properties. These properties can be used to separate the components by filtering, boiling, or other physical processes. What are the set of […]
What are the disadvantages of eddy current?
What are the disadvantages of eddy current? Disadvantages of Eddy Currents: There is a major heat loss during cycling eddy currents due to friction in the magnetic circuit, especially where the core is saturated. Thus there is the loss of useful electrical energy in the form of heat. There is magnetic flux leakage. How do […]

Is gravity getting stronger?
Is gravity getting stronger? Gravity is slightly stronger over places with more mass underground than over places with less mass. NASA uses two spacecraft to measure these variations in Earth’s gravity. These spacecraft are part of the Gravity Recovery and Climate Experiment (GRACE) mission. Why was my original gravity so low? Sparging – If you […]
How can electrons become excited?
How can electrons become excited? When an electron temporarily occupies an energy state greater than its ground state, it is in an excited state. An electron can become excited if it is given extra energy, such as if it absorbs a photon, or packet of light, or collides with a nearby atom or particle. What […]
