Answer:
Given: mass 1200kg
initial velocity: 4m/s
finial velocity: 10 m/s
time 3 sec
then
speed; initial velocity + final velocity/2
4+10/3
: 4.66m/s2
For Science fair project you can do convection current
Explanation:
Show how to do the process
and then make a model to demonstrate
Materials required:
Potassium Permanganate,beaker,bunsen burner,water and retort stand
The answer is Polar covalent. btw, this is chemistry work. not physics
An example would be a swimmer pushes on the wall with her feet, which causes the wall to push back on her feet due to Newton's third law
