Answer:
Ferrous metals are ones that contain iron ( can be alloys of iron), and non-ferrous metals don't contain iron.
Hope this helps, let me know if you have any questions! :)
Answer:
3349J/kgC
Explanation:
Questions like these are properly handled having this fact in mind;
Quantity of heat = mcΔ∅
m = mass of subatance
c = specific heat capacity
Δ∅ = change in temperature
m₁c₁(∅₂-∅₁) = m₂c₂(∅₁-∅₃)
m₁ = mass of block = 500g = 0.5kg
c₁ = specific heat capacity of unknown substance
∅₂ = block initial temperature = 50oC
∅₁ = equilibrium temperature of block and water after mix= 25oC
m₂= mass of water = 2kg
c₂ = specific heat capacity of water = 4186J/kg C
∅₃ = intial temperature of water = 20oC
0.5c₁(50-25) = 2 x 4186(25-20)
And we can find c₁ which is the unknown specific heat capacity
c₁ =
= 3348.8J/kg C≅ 3349J/kg C
The answers to the problem are as follows:

Answer:
a galaxy observed at a distance of 5 billion light-years
C. 10 m/s
You divide 1000 m by 100 s.
