Is it legal to brake check a tailgater? Yes it is illegal to brake check a tailgater. Causing an accident on purpose is illegal. Others have said that you can claim to have seen something dart into the road, but you have still caused an accident. Yes, tailgating is also illegal, but two wrongs do […]

How do rockets rotate? In flight, any rocket will rotate about its center of gravity, a point which is the average location of the mass of the rocket. Most rockets are symmetric about a line from the tip of the nose to the center of the nozzle exit. We will call this line the roll […]

Which type battery is best? Lithium-ion batteries What kind of batteries are least expensive? The most economical Li-ion battery in terms of cost-to-energy ratio is the cylindrical 18650 cell. Where is the cheapest place to buy batteries? For the best overall prices, consider shopping at one of these top five places to buy cheap batteries: […]

What is meant by one dimensional elastic collision? Two identical objects (such as billiard balls) have a one-dimensional collision in which one is initially motionless. After the collision, the moving object is stationary and the other moves with the same speed as the other originally had. Show that both momentum and kinetic energy are conserved. […]

What makes it easier to push heavy things answer? Answer: When you push there is one component of force that adds to the weight of the body and hence there is more friction. When you pull the vertical component of force is against the weight of body and hence there is less overall friction. So […]

Does the atomic radius increase from left to right? Atomic radius is determined as the distance between the nuclei of two identical atoms bonded together. The atomic radius of atoms generally decreases from left to right across a period. The atomic radius of atoms generally increases from top to bottom within a group. What is […]

What is the property of minerals that reflects light? Luster What are the two major properties of minerals? A mineral species is defined by two distinct properties: (1) its chemical com- position and (2) its crystal structure. Each mineral has a distinct three- dimensional array of its constituent atoms. This regular geometry affects its physical […]
