Answer:
Solar
Explanation:
The Hubble space telescope is a bus-sized satellite powered by huge solar panels.
Answer:
a)
Calculate the net power developed by using
the following relation:
Wste=W-W.
Substitute 8728 kw for w, and 2846 kw for w..
Wyle=8728 - 2846
= 5882 kW
Therefore, the net power developed is 5882 kW).

Step 6 of 7 A
Calculate the thermal efficiency by using the
following relation:
Here, e, is the heat input.
Substitute w, for ..
w
Substitute s882 kw for ws and 8728 kw for w.
5882
1-8728
67.39%
Therefore, the thermal efficiency is 67.39%).

Step 7 of 7 A
Calculate the back work ratio.
bwr =
Substitute 8728 kw for w, and 2846 kw for w..
bwr - 2846
bwr=8728
=0.326
Therefore, the back work ratio is 10.326).
Explanation:
Answer:
U=0.198J
Explanation:
The potential energy associated with two point charges is given as
U=(Kq1q2)/r
Where k=8.99*10⁹N.m²/C²
r=0.5m,
q₁=2μc,
q₂=5.5μc
If we substitute values into the equation we arrive at
U=(8.99*10⁹N.m²/C²* 2*10⁻⁶*5.5*10⁻⁶)/0.5
U=197.78*10⁻³
U=0.198J
From the calculation above, we can conclude that the potential energy between the two system of charges is 0.198J
Answer:
L= 312.75 mm
Explanation:
given data
elastic modulus E = 106 GPa
cross-sectional diameter d = 3.9 mm
tensile load F = 1660 N
maximum allowable elongation ΔL = 0.41 mm
to find out
maximum length of the specimen before deformation
solution
we will apply here allowable elongation equation that is express as
ΔL = 
....................1
put here value and we get L
L = 
solve it we get
L = 0.312752 m
L= 312.75 mm
