Answer:
193,210 J
Explanation:
Ec = (1/2)mv^2
m = 500kg
v = 27.8 m/s
Ec = (1/2)(500)(27.8)^2 = 193,210 J
Answer: it would be a 1 to 1 ratio
Explanation: originally it would be 2 to 2 but you have to reduce
2.12atm
Boyle's Law: P1V1 = P2V2
Manipulate to solve for unknown: P2 = P1V1/V2
Substitute values: P2=(1.2atm)(4.6L)/2.6L
P2 = 2.1230769atm
Round to 3 sig figs to get 2.12atm

As the atomic mass of iron is 55.847u
We say that it is the mass of one mole of iron.
By formula it can be find by
No.of mole=mass in g/molar mass
Mass in gram = no.of mole x molar mass
No.of mole =1
Molar mass = 55.847g
Mass in gram = 1x55.847
= 55.847g of Fe
