Answer:
x2=0.732m
Explanation:
We can calculate the spring constant using the equilibrium equation of the block m1. Since the spring is in equilibrium, we can say that the acceleration of the block is equal to zero. So, its equilibrium equation is:
Then using the equilibrium equation of the block m2, we have:
In words, the lenght x2 of the spring when the m2 block is hung from it, is 0.732m.
Answer:
Temperature
Polarity
Pressure
Solid and liquid solutes
Gas solutes
Molecular size
Stirring increases the speed of dissolving.
d = speed x time
distance = 29 x 30
distance = 870m
