1) nuclear fusion
During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. During this process, radiant energy is released.
 
        
             
        
        
        
Answer:

b).2.957kW
Explanation:
Using Inertia and tangential velocity
a).


Now using Inertia an w 

average power=
b).
power=t*w
P=
P=2.957 kW
 
        
                    
             
        
        
        
Answer:
Explanation:
a )
Each blade is in the form of rod with axis near one end of the rod 
Moment of inertia of one blade
= 1/3 x m l²
where m is mass of the blade 
l is length of each blade. 
Total moment of moment of 3 blades 
= 3 x x m l²
  x m l²
ml²
2 )
Given 
m = 5500 kg
l = 45 m 
Putting these values we get 
moment of inertia of one blade 
= 1/3 x 5500 x 45 x 45
= 37.125 x 10⁵ kg.m²
Moment of inertia of 3 blades 
= 3 x 37.125 x 10⁵ kg.m²
= 111 .375 x 10⁵ kg.m²
c )
Angular momentum 
= I x ω
I is moment of inertia of turbine 
ω is angular velocity
ω = 2π f 
f is frequency of rotation of blade
d ) 
I = 111 .375 x 10⁵ kg.m² ( Calculated )
f = 11 rpm ( revolution per minute )
= 11 / 60 revolution per second 
ω = 2π f 
=  2π  x  11 / 60 rad / s 
Angular momentum 
= I x ω
111 .375 x 10⁵ kg.m² x  2π  x  11 / 60 rad / s 
= 128.23 x 10⁵  kgm² s⁻¹ . 
 
        
             
        
        
        
Answer:
yes
Explanation:
because when you slow down, the resistance slows with the speed.
 
        
                    
             
        
        
        
Yes because if 0*c equals 32*F than the higher the number the hotter it is
