From 200 BC to around 14 AD, Rome had conquered most of Western Europe, Greece and the Balkans. Also the Middle East, and North Africa.
Answer:
13.5 km/h
Explanation:
John runs for 10 min at 9 km/h, then 20 min at v. He will have run a total of 30 min at 12 km/h.
Therefore:
(30 min) (12 km/h) = (10 min) (9 km/h) + (20 min) v
v = 13.5 km/h

Answer: A current of 1 A is flowing in a circuit if a charge of 1 coulomb passes any point in the circuit every second.
1 Amp = 1 Coulomb per second
We can write this formula as:
Current (I) = Charge (Q) / Time (t)
Charge (Q) = Current (I) x Time (t)
Explanation:
The realtionship between force in Newtons, mass in kilograms and acceleration in metres per second squared is described by Newton's second law of motion which is Force = mass times acceleration, or F=ma. You need to know the mass, so rearrange the formula to solve for m, giving m=F/a
In your example, the mass is therefore 8480 divided by 32, which is equal to 265kg.
