What are 6 different tests that are used to identify minerals?
What are 6 different tests that are used to identify minerals? Geologists use the following tests to distinguish minerals and the rocks they make: hardness, color, streak, luster, cleavage and chemical reaction. What are the two main types of mineral classification? Minerals are classified based on their crystal form and chemistry. Minerals are divided into […]
What happens when mercuric oxide and potassium nitrate are heated?
What happens when mercuric oxide and potassium nitrate are heated? When mercuric oxide is heated, it decomposes to give mercury and oxygen. Potassium nitrate on heating gets converted into molten potassium nitrite with the release of oxygen. What Happens When mercuric oxide is subjected to heating? Mercury(II) oxide, a red solid, decomposes when heated to […]
Are all projectiles parabolic?
Are all projectiles parabolic? Projectile motion is parabolic because the vertical position of the object is influenced only by a constant acceleration, (if constant drag etc. is also assumed) and also because horizontal velocity is generally constant. Why are parabolas important in real life? The parabola has many important applications, from the design of automobile […]
What are some good insulators?
What are some good insulators? Plastic, rubber, wood, and ceramics are good insulators. These are often used to make kitchen utensils, such as saucepan handles, to stop heat from flowing up to burn the cook’s hand. Plastic coating is also used to cover most electrical wires in appliances. Air is also a good insulator of […]

Does frequency change power?
Does frequency change power? Frequency of the system will vary as load and generation change. Increasing the mechanical input power to a synchronous generator will not greatly affect the system frequency but will produce more electric power from that unit. Can I use a 60 Hz device in a 50 Hz power frequency? Electrical machines […]
