WebbDensity is calculated using the formula d=M/V, where d represent density, M is mass and V is volume. The density of a substance is usually expressed in grams per cm. Water, for … WebbThe Current density formula as, J = J = J=0.33 A/m² Thus current density is 0.33 A/m² Q.2: Determine the current density of 100 Amperes of current is flows through the battery in an area of 10 m² ? Solution Given parameters Current I = 100 A, Area, A = 10 m² Now, applying the formula, J = J = = 10 A/m² Thus current density is 10 A/m². Browse

WebbThe weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. For an object in free fall, so that gravity is the only force acting on it, then the expression for weight follows from Newton's second law.
