Heat Transfer by conduction in solids, convection of fluids (liquids or gases), and radiation through anything that will allow radiation to pass. if this is not what are you looking for I am sorry :c
Answer:
F = 45 KN = 45000 N
Explanation:
Considering the downward direction as the positive direction:
where,
P = Resultant Pressure = ?
P₁ = Atmospheric Pressure = 100 KPa
P₂ = Pressure inside the can = 70000 Pa = 70 KPa
Therefore,
Now the resultant force will be given as:
where,
F = resultant force = ?
A = Area of side of can = 1.5 m²
Therefore,
<u>F = 45 KN</u>
Here, you need to apply second equation of Kinematics
S = ut + 1/2 at²
s = at²/2 [ As initial velocity (u) = 0 ]
Now, a = 9.8 m/s²
t = 2.7 s
Substitute their values in the formula:
s = 9.8 × (2.7)² / 2
s = 35.721 m
After rounding-off to the nearest hundredth value, it would be 36 m
Finally, your answer would be option B.
Hope this helps!

Explanation:
Thats to fast
When 2 forces act in the same direction the add together.
