Mybe i can solve another question!
Answer:
both kinetic energy and potential energy
Answer:
oxygen
Explanation:
as it is in the air it can't be depleted or used up
Pressure is given by:
P=F/A
force=1200*10=12000 N
Area=pi*r^2=3.14*0.15^2
=0.07065 m^2
Thus;
P=12000/0.7065
P=169,851.38 N/m^2
but
1 N/m^2=1 Pa
thus our pressure is:
169,851.38 Pa
