MARKING SCHEME (VERIFIED)
difference between renewable and non-renewable energy sources - ANS-1-non-renewable energy
sources will eventually run out 2- renewable energy sources can be replenished at the same rate that
they are used up
formula that links density mass and volume - ANS-Density = mass/volume
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
how to find specific heat capacity of water - ANS-measure mass of water using balance, measure initial
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
why would an ammeter show 0.0A for lll values of pot difference - ANS-if the diode has high resistance
in the opposite direction the current can not flow through it
