What is root in Newton-Raphson method? The root of a function is the point at which f(x)=0. Many equations have more than one root. Every real polynomial of odd degree has an odd number of real roots (“Zero of a function,” 2016). Newton-Raphson is an iterative method that begins with an initial guess of the […]

Concave mirrors are used in reflecting telescopes. They are also used to provide a magnified image of the face for applying make-up or shaving. Concave mirrors are […]

How do you find the specific resistance? Specific Resistance (”ρ”) is a property of any conductive material, a figure used to determine the end-to-end resistance of a conductor given length and area in this formula: R = ρl/A. Specific resistance for materials are given in units of Ω-cmil/ft or Ω-meters (metric). What are the two […]

Are people stronger at pulling or pushing? The results suggest that for our group of healthy recreationally active subjects, the upper body “pushing” musculature is approximately 1.5–2.7 times stronger than the musculature involved for pulling. Is pushing harder than pulling? Pulling is easier if you are taller than the object. Otherwise pushing would be easier. […]

Why is gravity weaker underwater? This is because water exerts a kind of frictional force called “force of buoyancy”. When you throw something into water , the water below the object will push it upwards making the object weigh less. Why is there no gravity under water? There is gravity everywhere. Gravity is just the […]
