 A quantity that is fully specified by measuring its size is called a: Scalar How much work is being done by a person holding a 60 pound suitcase 18 inches above the floor? None The force like quantity in the equation for electrical work is: Charge; if it has charge in or delta it's the force like quantity One ampere equals: one coulomb per second When a substance (such as water) goes from a solid to a liquid state without a change in temperature, the heat added during the transformation is called: Latent Heat Rearrange the formula, Rt=L/kA, to solve for L L=Rt(kA) What is Sensible heat? when heat is added to a substance and the temperature of the substance increases the heat is called this. What is Latent heat? When heat is added to a substance and the temperature DOES NOT change but the substance changes STATE, the heat thats added is called this. Tension, compression, bending, and twisting are kinds of mechanical: Stress A resultant force has both magnitude and: Direction The measure of gravitational pull is: Weight The SI units of mechanical force are: Newtons or kilogram weight Torque is a measure of what kind of force? Rotational Total pressure above zero pressure is: Absolute pressure In fluid systems, the quantity that has no units is: Specific Heat Sea level air pressure is: 14.7 lb/inches squared Voltage difference is measured with a/am: VOM A term that pertains to DC voltage is: Anode Heat energy moves from: Warmer regions to cooler regions Fluid-flow rate units such as "kg per min" or "gm per sec" are units of: Mass-Flow rate what is net force? determines which way it will move what is Equilibrium? if the system is at rest when the force are applied, it remains at rest. what is scalar value? gives only magnitude (how much) what is vector? gives both magnitude and direction what is absolute pressure? is the total pressure measured above a reference of zero pressure- a perfect vacuum Think of temperture difference as what? as Force what is heat energy? thermal systems are designed to move heat energy from warmer regions to cooler regions-usually to remove excessive heat what is force? push or pull what is an Electron? electrons are in a charge what is charge? needed for electrical systems to do work moves electricity
