Jenny loves puffed rice cereal. As she is pouring the cereal, two little pieces of cereal each with equal charges of 1.85 x10-18 coulombs
fall into the bowl 0.025 meters apart. Use Coulomb's Law to find the
electrostatic force between them. (Remember, Coulomb's constant
is 8.99 x10° N*m2/C2)
A-4.9 x 1023 N
B-6.2x 10-15 N
C-9.0 x 10-3 N
D-2.5 x 10-23 N

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

Which sections of the heating curve illustrate this process?
