Answer:
The specific heat is 3.47222 J/kg°C.
Explanation:
Given that,
Temperature = 13°C
Temperature = 37°C
Mass = 60 Kg
Energy = 5000 J
We need to calculate the specific heat
Using formula of energy
Put the value into the formula
Hence, The specific heat is 3.47222 J/kg°C.
Refer to the diagram shown below.
For dynamic balance,
1.5W - 2.5F = 0
W = (2.5*F)/1.5
= (2.5*40)/1.5
= 66.667 N
Because the lever is 80% efficient, the actual maximum load that can be lifted is
0.8*66.667 = 53.3 N
Answer: D. 53.3 N
