There’s 10mm in a cm: 22mm
A person is submerged of about 97.9%.
The average density of the human body is given as 979 kg/ m³.
<h3>Define Law of floatation.</h3>
Law of floatation can be defined as the volume of the liquid displaced when a body floats on the liquid surface is equal to the body submerged in the water.
As body has the stable equilibrium state, the buoyancy of the fluid will be equal to the weight.
Weight of the body floating = Weight of the body immersed in fluid
Law of floatation = Density of the floating object / density of fluid
As fluid is the freshwater here, the density of fluid will be 1000 kg/ m³.
= (979 kg/ m³) / ( 1000 kg/ m³)
= 97.9 %
A person is submerged when floating gently in fresh water about 97.9%.

Answer:
12294.31 m/s
Explanation:
Momentum = (mass)(velocity)
Momentum before = Momentum after
(momentum of bullet)+(momentum of block)=(momentum of bullet and block)
0.035v+50(0)=(0.035+50)(8.6)
0.035v=430.301
v=12294.3142857m/s
I suppose right answer is d because staellite means an object that move around the larger object and Jupiter also moves around the Sun
Answer:
Heat transfer q = 664015.5 J/kg (Approx)
Explanation:
Given:
Area = a
Velocity flow rate Q1 = 87a m³/s
Velocity flow rate Q2 = 360a m³/s
Find:
Heat transfer = q
Computation:
[P1][v1]/T1 = [P2][v2]/T2
[2][(87a]/300 = [1.45][360a] / T2
T2 = 900 K
Heat transfer q = Cp(T2 - T1) + (V2² /2 - V1² /2 )
Heat transfer q = 1,005(900 - 300) + (360² /2 - 87² /2)
Heat transfer q = 664015.5 J/kg (Approx)
