Modern wind turbines generate electricity from wind power. the large, massive blades have a large moment of inertia and carry a great amount of angular momentum when rotating. a wind turbine has a total of 3 blades. each blade has a mass of m = 5500 kg distributed uniformly along its length and extends a distance r = 46 m from the center of rotation. the turbine rotates with a frequency of f = 13 rpm.(a) enter an expression for the total moment of inertia of the wind turbine about its axis of rotation, in terms of the defined quantities.
(b) calculate the total moment of inertia of the wind turbine about its axis, in units of kilogram meters squared.
(c) enter an expression for the angular momentum of the wind turbine, in terms of the defined quantities. sig. gif? tid=0n86-9a-18-43-94ed-17253
(d) calculate the angular momentum of the wind turbine, in units of kilogram meters squared per second.

Since the pully is a simple machine so the mechanical advantage is a 1

Answer: a charge of -1.0  × 10⁻⁴ c must be placed  at x = 26 m.the sign of the charge will be the same sign as the  -4.0  µc charge.======electricstatic force between two point charges  is given by    where k is coulomb's constant,  8.99×10⁹  n·m²/c², q₁ and q₂ are the point charges, and r is the distance between the two point charges.assign positive to q₁let q₁ =  6.0 µc, q₂ = -4.0  µc, q₀ represent the charge at the origin, and q₃ represent this new charge to place.the charge at the origin q₀ would experience the following force f₀₁ from q₁, with r = 6.0 m (note that 1  µc = 10⁻⁶ c)    the force from q₂    the force from q₃    the net force on the origin charge, q₀, has to be zero for no electrostatic forcehaving an equation where k and q₀ can be divided out of the equation will allow us to solve for q₃    isolating:     a charge of -1.0  × 10⁻⁴ c must be placed  at x = 26 m.the sign of the charge will be the same as the  -4.0  µc charge
