Consider Einstein's famous equation, E = M C2, Find out the correct statement among the following?

1. Mass can be turned into energy, but energy cannot be turned back into the mass

2. Energy can be turned into the mass, but mass cannot be turned back into energy

3. The unit value of mass represents the 1 Joule of energy

4. Mass can be converted into energy if it travels with the speed of light.

Implement the following multiple output combinational logic circuit using a 4 line to

16-line decoder: F1= ∑m (0, 1, 4, 7, 12, 14, 15) F3= ∑m (2, 3, 7, 8, 10)

 F2= ∑m (1, 3, 6, 9, 12) F4= ∑m (1, 3, 5)

A shell-and-tube type of heat exchanger is designed to cool 1.512 kg/s of oil (Cp 2093 J/kg K) from 65.56° C to 42.22° C by using 1.008 kg/s of water at a inlet temperature of 26.67 °C. Assuming an overall heat transfer coefficient of 681.6 W/m²K and a single-shell, 2 tube pass type of heat exchanger determine the required heat transfer area. use the effectiveness method.
