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 […]
What is the relation between area and resistance?
What is the relation between area and resistance? Resistance depends on an object’s size, shape, and material. In Figure 3 below, the cylinder’s resistance is directly proportional to its length l. The longer the cylinder, the higher the resistance. Additionally, the resistance is inversely proportional to the cross sectional area A. What happens to the […]

Several Soviet and U.S. robotic spacecraft have landed on Venus and the Moon, and the United States has landed spacecraft on the surface of Mars. Does moon affect […]
Is gold a good heat reflector?
Is gold a good heat reflector? Surfaces designed to reflect a broad spectrum of electro-magentic waves, (shiny things generally, like mirrors or polished metal) specifically infrared wavelengths are good reflectors of radiant heat. Gold is the best material for reflecting radiant heat. Does gold Harden work? Heat: In general, Yellow Gold can be hardened by […]
When a ball is thrown up vertically with velocity u it attains a maximum height h What should be the velocity so that maximum height becomes 2h?
When a ball is thrown up vertically with velocity u it attains a maximum height h What should be the velocity so that maximum height becomes 2h? Thus maximum height attained becomes four times (4H) when the initial velocity is increased by 2 times. When a ball thrown up with velocity v0 it reaches the […]
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 […]

How are crumple zones designed?
How are crumple zones designed? The safety cell and crumple zones were achieved primarily by the design of the longitudinal members: these were straight in the centre of the vehicle and formed a rigid safety cage with the body panels, the front and rear supports were curved so they deformed in the event of an […]
