Answer:I think its the first one
Explanation:
Answer:
An object’s weight is proportional to its mass.
It will lead to rain. I know this because as the clouds move over water sources like oceans, lakes, and rivers, the water evaporates and rises. The water then liquefies into little water droplets. As the cloud moves over more water the droplets get scrunched up and get bigger over time and soon they get heavy and gravity pulls the droplets down to earth as rain. The End.
This would be a physical change because it can change back to its original form. This is like ripping paper. You can piece it back together and it still is paper.
The opposite of this is chemical change. Chemical change means the product has been changed completely like burning paper. The paper has now been turned to ash and it's impossible to change this back to its original form.
a = F/(m1+m2)
1.2 = F/48,000
F = 57,600N
a = F/(m1+m3)
a = 57,600/24,000
a = 2.4 m/s^2
