pls help me answer the following
Gauge TRUE OR FALSE Directions: Write TRUE if the statement is correct and FALSE if it gives incorrect information. Write your answer on a separate sheet of paper. 1. At constant temperature, the resistance of a conductor changes according to the applied voltage. 2. The electrical resistance of a wire would be expected to be greater for a longer wire, less for a wire of larger cross sectional area, and would be expected to depend upon the material out of which the wire is made. 3. Resistance and resistivity are the same.10.A cooler wire has less resistance than a warmer wire. Cooler particles have less kinetic energy, so they move more slowly. 1 1. The extremely thick wire has more resistance than a wider wire would. This helps the wire resist electric current and change it to light. 12.All materials have resistance. How much resistance a material has depends on the type of material, its width, its length, and its temperature. 13. Resistance is a hindrance when a material is being used to transmit electric current. Resistance is helpful when a material is being used to produce heat or light. 14.If the two charge bodies are opposite charge, work is needed to move them apart. 15. Electricity flowing through a wire is like water flowing through a hose. More water can flow through a wide hose than a narrow hose. In a similar way, more current can flow through a wide wire than a narrow wire.Activity 4: SOLVE ME! Direction: Read and analyze the following problems below. Write your answers correctly. Use a separate sheet of paper for your answers. 1. A current of one ampere is a flow of charge at the rate of coulomb per second. 2. When a charge of 8 C flows past any point along a circuit in 2 seconds, the current is A. 3. If 5 C of charge flows past in 10 seconds, then the current is A. 4. If the current is 2.0 A, then C of charge flow past in 10 seconds. 5. If 12 C of charge flows past point A in 3 seconds, then 8 C of charge will flow past in seconds.4. The resistivity does not depend on the temperature of most metal wires. 5. While maintaining a constant voltage (V), the current (I) increase when the resistivity p of a wire increases. 6. While maintaining a constant voltage (V), the current (I) decrease when the length (L) of a wire increases. 7. If the voltage across a circuit of constant resistance is doubled, I will decrese. 8. The electromotive force is the total voltage induces by the source. In other words, it is the amount of energy supplied by the source to each coulomb of charge. 9. A shorter wire has more resistance than a shorter wire. Current must travel farther through a longer wire, so there are more chances for it to collide with particles of matterStep by Step Solution
