Answer:
final equilibrium temperature is 65.02 ◦C
Explanation:
Given data
milk = 12 g
temp milk = 7◦C
coffee = 175 g
coffee temp = 69◦C
to find out
final equilibrium temperature
solution
we apply here equilibrium condition i.e m c ΔT
milk mass × c × ΔT = coffee mass × c × ΔT
12 × 1 × (T- 7) = 175 × 1 × ( 69- T)
12T - 84 = 12075 - 175 T
187 T = 12159
T = 65.02
so final equilibrium temperature is 65.02 ◦C

Answer:
20N
Explanation:
The force (Hooke's Law) is proportional to the deformation. To extend the spring 4 times longer, you will need 4 times the force. In total, 20 N
