A = change in v/t
= vf - vi / t
= 4.9 - 0 / 3
= 1.6 m/s^2
A and D make the most sence
Answer:
Iron metal is more reactive than copper.
Explanation:
Iron metal is more reactive than copper. ... Cu is less reactive than iron, therefore, cannot replace iron from iron sulphate (FeSO4). we have already seen that iron is more reactive than copper. So that means that in this reaction, copper is less reactive than iron. That means copper cannot displace iron. It cannot kick out iron from a sulfate.
Answer:
Constant Volume Calorimeter
Explanation:
In order to measure the heat released in burning of a gasoline, we generally use closed calorimeter. It is a constant volume calorimeter.
Most common example of such calorimeter is Bomb calorimeter.
We use closed calorimeter or constant volume calorimeter as large amount of heat is released during combustion of a fuel or gasoline.
