Acoal-fired power plant with effective stack height of 100 m emits 1.2 g/s of so2 per mw of power delivered. if winds are assumed to be 4 m/s at that height and just over 3 m/s at 10m, how big could the plant be (mw) without having the ground level so2 exceed 365 μg/m3? (first decide which stability classification leads to the worst conditions.)

What happens when chlorine reacts with bromine? a. electrons move from the chlorine atoms to the bromine atoms. b. electrons move from the bromine atoms to the chlorine atoms. c. electrons are shared between the chlorine atoms and the bromine atoms. d. electrons become delocalized among the atoms.

One object has a mass of 1 kg and another object has a mass of 3 kg. if the speeds are the same, which of the following is true about their kinetic energy?

3. a particle with initial velocity v⃗ 0=(5.85×103m/s)j^ enters a region of uniform electric and magnetic fields. the magnetic field in the region is b⃗ =−(1.35t)k^. you can ignore the weight of the particle. a. calculate the magnitude of the electric field in the region if the particle is to pass through undeflected, for a particle of charge +0.640 nc.
