What are two bad things about plate tectonics? Two bad things that can happen as a result of plate tectonics are: volcanoes and earthquakes. What is the implication of being near a plate boundary? If we choose to live near convergent plate boundaries, we can build buildings that can resist earthquakes, and we can evacuate […]
What is Lambda fuel ratio?
What is Lambda fuel ratio? Lambda represents the ratio of the amount of oxygen actually present in a combustion chamber compared to the amount that should have been present in order to obtain “perfect” combustion. Thus a lean air/fuel ratio of, say, 16:1 would translate to a lambda value of 1.088. (To calculate, divide 16 […]
Which of the following statement is correct about the magnetic field lines?
Which of the following statement is correct about the magnetic field lines? Magnetic field lines are continuous curves. It originate from north pole and terminate on south pole. But inside the magnet it moves from south pole to north pole forming a closed loop. So, there is no any origination or termination point like electric […]
Que se conserva en el choque elastico?
¿Que se conserva en el choque elastico? En física se dice que el choque entre dos o más cuerpos es elástico cuando se conserva la energía cinética total del sistema de cuerpos durante la interacción. ¿Qué efecto produce la energía cinetica en un choque? Colisiones. Si el choque es perfectamente inelástico (plástico) la energía cinética […]

How do you know if alkene is symmetrical?
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 […]
