Heat: a form of energy Heat In physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions.[1][2] The transfer of energy can occur in a variety of ways‚ among them conduction‚[3] radiation‚[4] and convection. Heat is not a property of a system or body‚ but instead is always associated with a process of some kind‚ and is synonymous with heat flow and heat transfer. Heat flow from hotter to colder systems occurs spontaneously‚ and is always accompanied by an

Modify the Multisim file to match the equivalent circuit you developed in problem #1 (Battery and two equivalent resistors). Run the simulation and compare the equivalent circuit’s results with the original circuit’s results. Are the results the same (YES/NO)? If no‚ determine why and correct it Yes the results are the same. 4. Construct the original circuit above

Main Control The function of main control consists of gizduino together with its basic functional circuit which are located at electric switch‚ inside electric switch is the relay shown in Figure 3.3‚ transistor shown in Figure 3.4‚ and resistor shown in Figure 3.5. In the sense that the appliances connection to the main control board was wired and also the use of relays to control switches. The function of control bit is to determine 0 or 1 binary output and then will trigger the relay

Grade 9 Task Term 3 Hydraulics and Pneumatics Section: A 1. a) Good examples of hydraulic systems include automotive brakes‚ and the control systems of large aircraft. Hydraulic systems supply forces somewhere remote from where it is practical to locate large machinery. Hydraulics gives high forces with low losses‚ thanks to the virtual incompressibility of hydraulic fluids. Pneumatics is usually less efficient‚ though simpler since the "reservoir" in the circuit is the atmosphere
