I have no idea
sorry
good luck thooooo!!
Answer:
halooooooo e in XP g t a goodvgk c and c are so much in XP go us XP thi to us go
A)
Atmospheric pressure is 101325 Pa.
Pressure = Force / Area
Area of table = 1.5 x 2.2
= 3.3 m²
Force = 101325 x 3.3
= 334 kN
B)
According to Newton's third law, every action has an equal and opposite reaction. Thus, the upward force is equal to the force acting downward on the table and is being balanced. The force is 334 kN in the upward direction.
Answer:
pressure=height × density×acc due to gravity
so
pressire is directly proportional to height hence it decreses with decrease in height
here air column height is measured upside down so decreases witn increment
1. One
2. Oohm
Hope this helps
