Answer:
P = VI
Explanation:
the power is equal to the current × voltage 
 
        
                    
             
        
        
        
(a) The average speed from A to B would be 1.76 metre per second and the average velocity from A to B would also be 1.76 metre per second 
<span>(b) The average speed from A to C would be 1.73 metre per second and the average velocity from A to C would be 0.87 metre per second</span>
        
             
        
        
        
Answer:
85.8 m/s
Explanation:
We know that the length of the circular path, L the plane travels is
L = rθ where r = radius of path and θ = angle covered 
Now,its speed , v = dL/dt = drθ/dt = rdθ/dt + θdr/dt 
where dθ/dt = ω = angular speed = v'/r where v' = maximum speed of plane and r = radius of circular path 
Now, from θ = θ₀ + ωt where θ₀ = 0 rad, ω = angular speed  and t = time,
θ = θ₀ + ωt = 0 + ωt = ωt
So, v = rdθ/dt + θdr/dt 
v = rω + ωtdr/dt 
v = (r + tdr/dt)ω 
v = (r + tdr/dt)v'/r
v = v' + tv'/r(dr/dt)
v = v'[1 + t(dr/dt)/r]
Given that v' = 110 m/s, t = 33.0s, r = 120 m and dr/dt = rate at which line is shortened = -0.80 m/s (negative since it is decreasing)
So, v = 110 m/s[1 + 33.0 s(-0.80 m/s)/120 m]
v = 110 m/s[1 + 11.0 s(-0.80 m/s)/40 m]
v = 110 m/s[1 + 11.0 s(-0.02/s)]
v = 110 m/s[1 - 0.22]
v = 110 m/s(0.78) 
v = 85.8 m/s
