negative impacts of wind turbines - ANS-wildlife collisions including bats and birds, noise pollution,
visual impacts



negative impacts of tidal turbines - ANS-less visual impacts, affects sea life,



hazard of finding specific heat capacity of water - ANS-electricity near water

temp of water, turn on heater and joulemeter and leave for 10 mins, measure joules, final temp and
calculate the temperature change, find specific heat capacity by using the formula heat energy/ mass of
substance x change in temperature



one way to prevent energy loss - ANS-add lid to beaker



one way potential difference can be varied across the led - ANS-change resistance on the variable
resistor
