As velocity = displacement /time
Then dispalcement=150 km = 0.15 m
time=1700 s
velocity= displacement / time
= 0.15/1700
=0.0000882353 m/s
Use the specific heat equation to solve this.
Answer: Energy = 10000J - 2000J = 8000J
Therefore, the energy is dissipated the skier moves down to the slope is 8000J
Explanation:
Answer:
Explanation:
Calcium bicarbonate dissolved in hard water can easily be removed by heating the hard water . On heating , it decomposes to give calcium carbonate which is insoluble and therefore can be filtered out .
Ca( HCO₃)₂ = CaCO₃ + CO₂ + H₂O.
In this way hardness of water is removed .
No, not every collision makes a reaction.
