Transformer EMF Calculation: EMF is nothing but a voltage which built at the transformer terminal when you apply voltage at another winding. EMF E (V) in volts is equal to the 4.44 times of product of frequency F (Hz) in Hertz, maximum flux ϕ m in Weber and the number of conductor N in number. EMF equation can be written as,

The total (kinetic) energy of an object which rolls without slipping is given by Eq. 2.4. To use this equation we have everything we need except the angular speed of the ball. From Eq. 2.2 it is related to the linear velocity of the ball by vCM = Rω, so the angular speed is ω = vCM R = (4.0 m s) (0.10m) = 40.0 rad s and then the kinetic.

In describing the motion of rolling objects, it must be kept in mind that the kinetic energy is divided between linear kinetic energy and rotational kinetic energy. Another key is that for rolling without slipping, the linear velocity of the center of mass is equal to the angular velocity times the radius. Sphere on incline. Hoop and cylinder.

Give the equation of the reaction involved. When a solution of sodium hydrogen carbonate is heated, it decomposes to form sodium carbonate with the evolution of carbon dioxide gas. The equation of the reaction involved is:

CKD-EPI Equations for Glomerular Filtration Rate (GFR) Estimates GFR based on serum creatinine, serum cystatin C, or both. IMPORTANT The 2021 CKD-EPI equation is now the recommended standard. This version does not include race, as do the 2009 and 2012 CKD-EPI creatinine and creatinine-cystatin C equations.

C a S O 4 .2 H 2 O → C a S O 4 .1 / 2 H 2 O + 1 1 / 2 H 2 O (c) Plaster of Paris should be stored in a moisture-proof container because the presence of moisture can cause the slow setting of plaster of paris by bringing about its hydration. (d) The two important uses of plaster of pairs is given below: It is used for healing the fracture of bones.

Question: Benzene (C6H6) burns according to the following balanced equation: C6H6 (l)+152O2 (g)→6CO2 (g)+3H2O (g) Part A Calculate ΔH∘rxn for this reaction using standard enthalpies of formation. (The standard enthalpy of formation of liquid benzene is 49.1 kJ/mol.) Please show ALL work. Calculate Δ H ∘rxn for this reaction using.

answered • expert verified. Metal compound A reacts with dilute hydrochloric acid to produce effervescence. The gas evolved extinguishes a burning candle. Write a balanced chemical equation for the reaction if one of the compounds formed is calcium chloride.

In a balanced chemical equation, the total number of atoms of each element present is the same on both sides of the equation. Stoichiometric coefficients are the coefficients required to balance a chemical equation. These are important because they relate the amounts of reactants used and products formed.
