Answer:
Solar
Explanation:
The Hubble space telescope is a bus-sized satellite powered by huge solar panels.
Answer:
a) ≈ 30 mins
b) 8 vpm
Explanation:
<u>a) Determine how long after the first vehicle arrival will the queue dissipate</u>
The time after the arrival of the first vehicle for the queue to dissipate
= 29.9 mins ≈ 30 mins
<u>b) Determine the average service rate at the parking lot gate </u>
U = A / t
where : A = 240 vehicles , t = 30
U = 240 / 30 = 8 Vpm
attached below is a detailed solution of the given problems above
Answer:
<em>a) 42 mm</em>
<em>b) 144.4 MPa</em>
<em></em>
Explanation:
Load P = 200 kN = 200 x 10^3 N
Torque T = 1.5 kN-m = 1.5 x 10^3 N-m
maximum shear stress τ = 100 Mpa = 100 x 10^6 Pa
diameter of shaft d = ?
From T = τ *
* 
substituting values, we have
1.5 x 10^3 = 100 x 10^6 x
x 
= 7.638 x 10^-5
d =
= 0.042 m = <em>42 mm</em>
b) Normal stress = P/A
where A is the area
A =
=
= 1.385 x 10^-3
Normal stress = (200 x 10^3)/(1.385 x 10^-3) = 144.4 x 10^6 Pa = <em>144.4 MPa</em>
Answer:
Ancestor are our great grandparents
Answer:
b) decreased
Explanation:
Viscosity is the measure of the resistance between the layers of the liquid. On increasing temperature, the kinetic energy of the molecules of the liquid increases which in turn increase in the random motion of the molecules. Thus, the relative motion of the molecules in the liquid become easier and hence, viscosity decreases.
