Explanation:
If the family needs 26 kW of power, and knowing that the efficient is 30% the relation between the solar flux and the power would be:
(1)
e is the efficient (in our case 0.3)
Φsolar is the solar flux
S is the effective surface
Solving (1) for S we have:
I hope it helps!
Answer:
a)
b)
c)
Explanation:
From the question we are told that
Mass of soft rubber
Spring compression
Stiffness constant
Ball Distance
Frictional force
a)Generally the equation for motion of the second ball according to Newton's law is given by
b)Generally for speed to be at maximum spring force must equal frictional force
At distance
Therefore
Ball is at maximum speed at
c)Generally maximum velocity is represented mathematically as
The angle of bank needed, measured from the vertical is 86.6⁰.
<h3>
Banking angle of the circular path</h3>
The angle of bank needed, measured from the vertical is calculated as follows;
v = √(rg tanθ)
where;
- v is the speed = 1440 km/h = 400 m/s
- r is radius of the curve = 960 m
- g is acceleration due to gravity
- θ is the banking angle
400² = (960 x 9.8 x tanθ)
tanθ = 400²(960 x 9.8)
tanθ = 17
θ = arc tan(17)
θ = 86.6⁰
Thus, the angle of bank needed, measured from the vertical is 86.6⁰.
