1. If 20 g of ice at 0 °C is added to 180 g of water at 22 °C, what will the final temperature of the water be? (3 marks) 2.When a 120 g sample of aluminum (Al) absorbs 9612 J of energy, its temperature increases from 25 °C to 115 °C. What is the specific heat of aluminum? (3 marks)

low freq = 100 mhz

low wavelength =101.7m

length = 3x10^8/freq

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

i would like to make dinner for my mom, dad, and sister

what is the actual question though?
