2. how much work does gravity do in causing a 6 kg hammer to fall to the ground from a
height of 10 m?

600 J = 600 N m (newton meters)

Explanation:

To do this quickly, we should know that this question is asking us to how much work has been done on the object - and...because its falling from a height, we can switch this up to ask - "what is the change in potential energy of the object?" Which means that we can use this formular - PE = mgh where.....

m = the mass of the object

g  = the accerlation due to gravity and...

h  = which is the height of the falling object.

When we put that all together we get; PE =

Multiplying everything out gives 600 J or joules, which also equals 600 N m.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

idk im sorry.
