A certain parallel-plate capacitor is filled with a dielectric for which k = 6.50. The area of each plate is 0.0524 m², and the plates are separated by 2.97 mm. The capacitor will fail (short out and burn up) if the electric field between the plates exceeds 179 KN/C. What is the maximum energy that can be stored in the capacitor? Number i Units J

Q. 1/ piece of copper, whose length is 10 cm and the area of its section is 6 cm2. Fix one end of it on 150c and make the other end tangent to a piece of iron of 8cm length and equal to it with the cross-sectional area and straight to one, and the temperature of the piece of iron was 20c. Calculate the contact point temperature between the two pieces, noting that the thermal conductivity coefficient of copper is Scmc / [0.85, while for iron it is 0.75] / ScmC.
A storage tank is connected to a piping system as illustrated in Figure P1. Water at temperature of 20°C in the storage tank flows through a piping system with the pipe's diameter of 5 cm and discharges from a nozzle to the atmospheric at velocity of 3.5 m/s. The diameter of the nozzle is 3cm. Galvanized pipe is used and installed in this piping system. All the fitting components installed in this system such as regular 90° and tees are flanged type. The Water at 20°C 21 m D= 5 cm d- 3 cm After 5 years of operation, the accumulation of the dirt and other micro particles stained on the pipe's wall surface have significantly reduced the water discharge from the nozzle. Please explain this phenomenon.
