Heat required to raise the temperature of water is given as

here we have
m = 100 g = 0.100 kg
s = 4183 J/kg C

now we can use the above equation


so here it requires 20920 J heat to raise the temperature of 100 g water by 50 degree C
Answer:
b. B, A, C
Explanation:
To solve this problem, let us find the net forces they are experiencing.
Net force = mass x acceleration
Object A; mass = 8kg and acceleration = 4m/s²
Net force = 8 x 4 = 32N
Object B; mass = 10kg and acceleration = 3m/s²
Net force = 10 x 3 = 30N
Object C: mass = 7kg and acceleration = 5m/s²
Net force = 7 x 5 = 35N
So, increasing order of their net force;
B < A < C
