Answer:
Explanation:
25 mm diameter 
r₁  = 12.5 x 10⁻³ m radius.
cross sectional area =  a₁
Pressure P₁  = 100 x 10⁻³ x 13.6 x 9.8 Pa 
a ) 
velocity of blood v₁ = .6 m /s 
Cross sectional area at blockade = 3/4 a₁
Velocity at blockade area = v₂
As liquid is in-compressible 
a₁v₁ = a₂v₂
a₁ x .6 m /s  = 3/4 a₁ v₂
v₂ = .8m/s
b )
Applying Bernauli's theorem formula 
P₁ + 1/2 ρv₁² =  P₂ +  1/2 ρv₂² 
100 x 10⁻³ x 13.6 x10³x 9.8 + 1/2 X 1060 x .6² = P₂ +  1/2x 1060 x .8² 
13328 +190.8 = P₂ + 339.2
P₂ = 13179.6 Pa
= 13179 / 13.6 x 10³ x 9.8 m of Hg
P₂ =  .09888 m of Hg
98.88 mm of Hg
 
        
             
        
        
        
The distance covered is 115 m
Explanation:
The motion of Ileana is a uniformly accelerated motion (constant acceleration), therefore we can use the following suvat equation:

where
s is the distance covered
u is the initiaal velocity
v is the final velocity
t is the time elapsed
In this problem, we have:
u = 4.20 m/s
v = 5.00 m/s
t = 25.0 s
Therefore, we can re-arrange the equation to find the distance covered:

Answer:

Explanation:
Moment of inertia of given shell
where
M represent sphere mass
R -sphere radius
we know linear speed is given as 
translational 
rotational 
total kinetic energy will be 


fraction of rotaional to total K.E

 
        
             
        
        
        
Because it demonstrates the relationship between a body and the forces acting upon it, and its motion in response to those forces. [Hope that helps]
