Adiabatic process is that process in which heat of a closed system will remain conserved or we can say that system can not exchange its thermal energy from its surrounding
So here from 1st law of thermodynamics we can say
since we know that
so we will have
so we have
so here correct answers are
<em>A. -ΔU = W </em>
<em>B. Heat is constant. </em>
Answer:
0.25 N
Explanation:
The density of the ball () = 0.0839 g/cm³ = 83.9 kg/m³
The density of water () = 1000 kg/m³
diameter = 3.77 cm = 0.0377 m
radius of ball = 0.0377/2 = 0.01885 m
The volume (V) =
Let us assume the acceleration due to gravity (g) = 9.8 m/s²
Hence:
The force is required to hold it completely submerged under water (F) is:
F = 0.25 N
