TAQ 3:
What is an atom? What are atoms made of?
You can use diagrams to illustrate your answer.
Protons and neutrons are both composed of other particles called quarks and gluons. Give details of the three families of quarks and explain where they are found.
Use the information in the table below to determine the quark composition of a neutron. Show how you arrived at your answer.
neutron
Q (relative charge) 0
B ( Baryon Number) 1
S (Strangeness) 0
WORD COUNT
250 WORDS
NOTE:
Completion notes:
The more detail you present relating to the fundamental particles the better, you can research some particles that our learning material has not covered
TAQ 4:
Explain what is meant by the following terms with respect to electricity:
Current, charge, work, power, resistance and voltage.
If I increase the resistance in a circuit and the voltage remains the same, what happens to the current? Which law does this reflect?
The circuit diagram shows a 12V dc supply of negligible internal resistance connected to an arrangement of resistors. The current at three places in the circuit and the resistance of two of the resistors are given on the diagram.
Calculate:
total resistance of the circuit
current through the 16V cell
voltage across the 6Ω single resistor
current through the 9Ω resistor and the 18Ω resistor in parallel
