Answer:
a) 46.76 Lsun
b) 2187 Lsun
c ) You can easily estimate the luminosity of a 3-solar massed giant star because its luminosity is close to the luminosity of the sun
Explanation:
To estimate the luminosity of a celestial body in terms of solar luminosity we use the expression below
= 
a) Estimate the luminosity of a 3 solar mass main sequence star
=
Hence ; L(luminosity of a 3 solar mass star ) = 46.76 Lsun
b) Estimate the luminosity of a 9-solar-mass main sequence star
= 
hence L( luminosity of a 9-solar mass star ) = 2187 Lsun
c ) You can easily estimate the luminosity of a 3-solar massed giant star because its luminosity is close to the luminosity of the sun
The zero-force members in the truss are BE and BC. This is because they are the two non-collinear members.
<h3>How would you identify zero-force members in truss?</h3>
You would definitely identify zero-force members in a truss by the fact that a joint has only two non-collinear members and there is no external load or support reaction at that joint, then those two members are zero-force members.
Zero-force members in a truss are the structural members that significantly support no loading but aid in the stability of the truss.
Therefore, the zero-force members in the truss are BE and BC. This is because they are the two non-collinear members.

Answer:
- price = 380
- dollar = (price // 100) + 1
- print(dollar)
Explanation:
Presume the an item cost 380 cents and we set 380 to the variable price (Line 1). To estimate the number of single dollars to be paid, we can use // operator to divide price by 100 and we will get 3 (the remaining decimal point will be discarded). Then we add 3 by one. So the expression is
(price//100) + 1
*The reason we divide price by 100 is because 1 dollar = 100 cents
Answer:
Option E
The planning and construction of the resorts represent an impact lag of this policy.
Explanation:
Whereas the legislation was enacted without any delay but planning takes six months and construction taking 2 months, it means the policy has a lag. Therefore, option E, the planning and construction of the resorts represent an impact lag of this policy.
