Answer:
The required specific heat is 196.94 joule per kg per °C
Step-by-step explanation:
Given as :
The heat generated = Q = 85.87 J
Mass of substance (m)= 34.8 gram = 0.0348 kg
Change in temperature = T2 - T1 = 34.29°C - 21.76°C = 12.53°C
Let the specific heat = S
Now we know that
Heat = Mass × specific heat × change in temperature
Or, Q = msΔt
Or, 85.87 = (0.0348 kg ) × S × 12.53°C
Or , 85.87 = 0.4360 × S
Or, S =
∴ S = 196.94 joule per kg per °C
Hence the required specific heat is 196.94 joule per kg per °C Answer
Answer:
Pretty Sure all except D. and E. are true
Step-by-step explanation:
The text states the ship reaches 236 dt above sea level proving A. true
The ship also reaches -74 ft below sea level meaning it goes 74 ft undersater proving B.
The 74 ft plus the 236 ft show that the ship's full size is more than 236 alone proving C. correct
and proving D. and E. false as well
