How do you know if alkene is symmetrical? A symmetrical alkene is an alkene in whose molecule the doubly bonded carbons bear the same ligands. eg. 1: In 1, each double bonded carbon bears two methyl groups. How do you identify asymmetric carbon? A carbon atom is asymmetric if it has four different chemical groups […]
What is the difference between indication and contraindication?
What is the difference between indication and contraindication? In medicine, a contraindication is a condition that serves as a reason to not take a certain medical treatment due to the harm that it would cause the patient. Contraindication is the opposite of indication, which is a reason to use a certain treatment. What are contraindications […]
How can I be perfect in physics?
How can I be perfect in physics? Best Ways to Study and Do Well in Physics: Good understanding of the basics: Memorizing basic equations: Strengthening your math skills: Studying derivations: Analyze problems: Focus on important aspects of each problem: Utilize drawings: Making use of correct units: Is physics harder than math? General perception: Physics is […]
Can we charge an insulator?
Can we charge an insulator? Charge cannot flow along or through an insulator, so its electric forces remain for long periods of time. (Charge will dissipate from an insulator, given enough time.) Do conductors attract insulators? If the insulator started with positive charge on it, that means electrons are missing inside of it. The electrons […]
In what direction is the net force exerted on the moon?
In what direction is the net force exerted on the moon? We know from Newton’s second law of motion that an object experiencing a net force undergoes acceleration. In the case of the moon orbiting the Earth (or any object orbiting another object to which it is attracted by some force), the net force on […]
What is the process of an electromagnet?
What is the process of an electromagnet? An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil. […]
Who invented inches?
Who invented inches? The old English ynce was defined by King David I of Scotland about 1150 as the breadth of a man’s thumb at the base of the nail. To help maintain consistency of the unit, the measure was usually achieved by adding the thumb breadth of three men—one small, one medium, and one […]
Can the resultant of 3 vectors be zero?
Can the resultant of 3 vectors be zero? Answer. Three vectors are coplanar which means all three vectors are in the same plane. If direction of resultant of those two vectors is exactly opposite to the direction of the third vector. If all above conditions are satisfied, then the resultant of three vectors will be […]
What causes wave refraction?
What causes wave refraction? Refraction is the bending of a wave-front as it travels at different speeds over water of different depths. When different parts of the same wave-front travel at different speeds, the wave bends towards the slower part. The shallower the water, the slower the wave; therefore the wave bends towards the shallower […]
What is the chemical name for AlF3?
What is the chemical name for AlF3? Aluminum fluoride Where is aluminum fluoride found? Fluoroaluminate glass is found in optical fiber applications, such as fiber-optic imaging and medical applications. Aluminum fluoride is commonly used in ceramics, where it is found as the main chemical compound in glazes for finished products. Is aluminum trifluoride ionic? Al […]
