The bottle's mass is 0.2 kg. The diameter of its base is 10cm. How much pressure does the bottle exert on the table? A) 64 Pa B) 25 Pa C) 6.4 Pa D) 255 Pa

D) 255pa

Explanation:

pressure= force/area

force = weight

weight= mass* gravitational acceleration

weight= 0.2kg*10m/s²

weight= 2N

area= πr² where r=1/2diameter

r=1/2diameter

r=1/2(10cm)

r=5cm or 0.05m

area= πr². where π 's approximate value is 3.14

area=3.14(0.05m)²

area=3.14 * 0.0025m²

area=0.00785m²

pressure= force/area

pressure=2N/0.00785m²

pressure=255pa approximately

the results is a decrease in air temperature with an increase of altitude.
