How do you prove an electric field is perpendicular to equipotential surface? An equipotential surface is circular in the two-dimensional. Since the electric field lines are directed radially away from the charge, hence they are opposite to the equipotential lines. Therefore, the electric field is perpendicular to the equipotential surface. Is electric field constant on […]

What is the equation for the mechanical advantage of a lever? To calculate the mechanical advantage of levers, you can use one of two formulas. 1. Mechanical advantage = effort distance / resistance distance (MA = ED / RD) This formula is used when given meters. The distance of effort is the distance from the […]

Who is stronger Colossus or Juggernaut? According to the (Original) Official Handbook of the Marvel Universe (from the 80’s), Colossus could lift (press) 70 tons. He fought Juggernaut and lost, but held his own because of the durability of his Organic Steel form. Juggernaut has always been “class 100” strength (on par w/ Thor & […]

Do sled dogs get whipped? Iditarod sled dog puppies are beaten with whips, shovels, tree branches or anything else that’s within easy reach. Mushers beat their dogs with quirt whips. The whip has two tails at the end, and a core that’s normally filled with lead shot. Mushers roll up their whips and hide them […]

What is Q for an isothermal expansion? In other words, in an isothermal process, the value ΔT = 0 but Q ≠ 0, while in an adiabatic process, ΔT ≠ 0 but Q = 0. For an ideal gas, the product PV (P: pressure, V: volume) is a constant if the gas is kept at […]

How much G force can a human take? Normal humans can withstand no more than 9 g’s, and even that for only a few seconds. When undergoing an acceleration of 9 g’s, your body feels nine times heavier than usual, blood rushes to the feet, and the heart can’t pump hard enough to bring this […]

What is a unique zero? ag.algebraic-geometry nt.number-theory algebraic-number-theory. Suppose p is a point in Rn so that among the set S of polynomials in Z[x1,…,xn] which equal zero at p, p is the only point in some neighborhood of p at which all of them equal zero. How do you tell if a function has […]
