Answer: the answer would be a lower specific heat.
Explanation:
The answer would be c as the cart is not in motion therefor ruling out kinetic and it is completely at rest making all of it energy potential
Answer: 32 kcal
Explanation:
![Q= m\times c\times \Delta T](https://tex.z-dn.net/?f=Q%3D%20m%5Ctimes%20c%5Ctimes%20%5CDelta%20T)
Q= heat gained or lost
m= mass of the substance = 874.3 g
c = heat capacity of water = 1 cal/g ° C
![Q=874.3g\times 1cal/g^oC\times 36.61^oC](https://tex.z-dn.net/?f=Q%3D874.3g%5Ctimes%201cal%2Fg%5EoC%5Ctimes%2036.61%5EoC)
Q= 32008.1cal=32..0kcal (1kcal=100cal)
Thus heat lost by 874.3 g of iron is = 32 kcal
Heat lost is represented as a negative sign.
Ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
