7. A capacitor of capacitance 500 uF is charged to V volts. It is then
discharged through a small coil of resistance wire embedded in a
thermally insulated block of specific heat capacity 2.5 x 102 Jkg 'K' 9.
and of mass 0.1 kg. If the temperature of the block rises by 0.4K,
what is the value of V?

Alexander calder's mobiles are an example of motion because it uses forces of wind and water.

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.
