Using Fruits ( Lemon‚ Orange ) As Battery Purpose To demonstrate how an electrical current can be generated using citrus fruits (such as lemons or limes) that is strong enough to power a small light bulb. Additional information Batteries are devices that store chemical energy and convert it to electrical energy. Consisting of one or more voltaic cells‚ batteries come in various sizes and forms and are integrated into most electronic and portable devices. Electrical current is the flow

Biology Lab Report BY: Michael Ryan Pranata 11C | Background: As heat is a form of thermal energy‚ they tend to have the behavior of reaching a thermal equilibrium. This means that when two bodies of different temperatures come in contact with each other‚ the hotter ones will transfer heat particles to the body with a colder temperature‚ with an aim to reach this “thermal equilibrium”‚ whatever the temperature may be. The larger the surface area‚ means there can be more “paths” from the

Tutorial 1 (Conduction and Convection) 1. Consider a composite structure shown on below. Conductivities of the layer are: k1 = k3 = 10 W/mK‚ k2 = 16 W/mK‚ and k4 = 46 W/mK. The convection coefficient on the right side of the composite is 30 W/m2K. Calculate the total resistance and the heat flow through the composite. (0.46‚ 173.9 W) 2. Consider a 1.2-m high and 2-m-wide glass window whose thickness is 6 mm and thermal

Jim Lovell. The flight was planning on landing on the moon but unfortunately something went wrong‚ one of two fuel cell oxygen tanks in the service module had exploded. Damaged Teflon insulation on the wires to the stirring fan inside oxygen tank 2 allowed the wires to short-circuit and ignite the insulation. The lives of the three astronauts were threatened because of the massive internal damage in the spacecraft. NASA had to make the decision between landing on the moon and getting home safely
