Year 8 Science Test Welcome to your Year 8 Science Test Name Email Match them to their meaning Frequency Trough Wavelength Amplitude Time period Peak the time taken for one complete cycle of the wave the number of complete vibrations in one second the highest point of a transverse wave The distance from one peak to the next pea the lowest point of a transverse the distance from a peak or a trough, to the rest position Match them to their answers C D A B Peak Trough Wavelength Amplitude Fill the in gap (a) Waves P and Q have the same , but wave P has twice the of wave Q.(b) Waves Q and R have the same ,but wave R has twice the of wave Q.(c) Wave shows a steady frequency but changing amplitude.(d) Wave shows steady amplitude but a changing frequency.(e) Waves and have a low amplitude and a steady frequency Match them to their functions capillaries arteries veins A somewhat elastic, muscular-walled vessel taking blood towards the heart Tiny blood vessels which carry blood into and out of all tissues in the body An elastic, muscular-walled vessel taking blood away from the heart. Match the to their structure arteries veins capillaries They have very thin walls one-way valves in your veins stop it flowing backwards made of thick muscle to withstand this pressure Tick TWO the products of photosynthesis Carbon dioxide Water Light Glucose Oxygen Match them to their functions potential difference voltmeter Switch current Fixed resistor ammeter device used to measure potential difference or voltage device used to measure electric current supply is a measure of the energy restricts or limits the flow of electrical current Moving electric charges used to turn a circuit Time's upYou cannot switch tabs while taking this quiz!You are not allowed to switch tabs violation has been recorded.you cannot minimize full screen mode!You are not allowed to minimize full screen while taking this quiz, violation has been recorded.Access denied!
