Question
Two identical masses of 5 kg each fall on a wheel from a height of 10m. The wheel disturbs a mass of 2kg water, the rise in temperature of water will be : -
Options
A.2.6oC
B.1.2oC
C.0.32oC
D.0.12oC
Solution
Entire KE gets converted into heat.
ᐃKE = msᐃθ ⇒ 10 × 10 × 10 = 12 × 4200 × ;ᐃθ ⇒ ᐃθ = 0.12oC
ᐃKE = msᐃθ ⇒ 10 × 10 × 10 = 12 × 4200 × ;ᐃθ ⇒ ᐃθ = 0.12oC
