Power=20 watts
<span>1.0 gram (g) of electrons would contain 10^27 electrons
Electrons have an electric charge of −1.602×10−19 coulomb
so total charge of 1 g electrons = -1.602 x 10^-19 x 10^27 = -1.602 x 10^8</span>
<span>The centripetal force for such an arrangement can be found through the equation Fc = mv^2/r where m is the mass of the rotating object, v is that object's velocity, and r is the radius of rotation. In this case, we know that the maximum Fc that can be tolerated by the cord is 64N. Thus we set the equation up and solve for the value of v for which Fc = 64.
64 = 0.4*(v^2)/1
64/0.4 = 160 =
v^2
v = sqrt(160) = 12.65 m/s
At any speed faster than 12.65 m/s, the cord will break.</span>
Answer:
Ca + ZnCO3 → CaCO3 + Zn
Explanation:
Ca + ZnCO₃ = CaCO₃ + Zn
Ca + ZnCO3 → CaCO3 + Zn is the answer.
Here Ca and ZnCO₃ are reactant and CaCO₃ and Zn are product . Reactants are written on the left side of equation and product are written on the right side.
