    Topic 4- summarised:
    Ultrasound- sound frequency HIGHER than 20000Hz
    - Used for pre-natal scanning and sonar.

    Infrasound-Sound frequency BELOW 20Hz
    -Animal communication

    P-waves- LONGITUDINAL and FAST moving. They can also travel through liquids and solids.
    S-waves- Transverse waves and they are SLOW moving. Travel through SOLIDS ONLY.

    Personally, I'm hoping for lifecycle of stars. I think Renewable/non renewable could come up and transformers may come up. Telescopes is a bother potential as well.

    Yes, they should be. What did you get for the secondary coil question?

    Who took the physics exam in May? Do you think that it was hard? I'm worried about what grade ill get overall as I think I have done ok in biology and chemistry but physics let me down. In my physics mock exam earlier this year in April I got a U in physics, C in biology and another C in Chemistry
