Your stomach, as in JUST your stomach?
Well the role of your stomach is to break down large clumps of food. Without that it would be very hard to impossible to digest food.<span />
Answer:
F = 3.98 kN
Explanation:
GIVEN DATA:
sides of box = 17 cm
pressure = 1 atm = 101325 N/m2
T2 = 378K
T1 = 278 K
final pressure can be calculate by using below relation

we know that
force = pressure * area
therefore force is


F = 3.98 kN
Answer:
The value of the acceleration of gravity of the Unknown Planet = 1.14 
Explanation:
length of the pendulum (L)= 1.15 m
Time period (T)= 6.29 seconds
We know that time period of a simple pendulum is given by
⇒ T = 2
×
put the values in the above formula we get
⇒ T = 2
× 
⇒ 6.29 = 2
× 
By solving the above equation we get
⇒ g = 1.14 
This is the value of the acceleration of gravity of the Unknown Planet.
