Answer:
horizontal structural member that supports a floor. Beams are typically wood, cold formed metal framing or steel.
Joists
Horizontal timbers, beams or bars supporting a floor.
Answer:
The unit you should use for work done and energy is the joule (J) which is indeed the same as the newton metre (N m).
There is another physical quantity which is the product of force and distance and that is torque or moment of a force.
The unit you should use for torque is the newton metre (Nm) and not the joule.
Naming the units of work done and torque differently helps to emphasis the fact that work done and torque refer to two different physical quantities although the definitions of both quantities have the product of force and distance in them.
work done=force→⋅displacement→ and torque→=force→×displacement→

A low-luminosity star has a small and narrow <u>habitable zone</u>, whereas a high-luminosity star has a large and wide one.
<h3>What is luminosity of a star?</h3>
The radiant power emitted by a light-emitting item over time is measured as luminosity, which is an absolute measure of radiated electromagnetic power (light).
The total quantity of electromagnetic energy released per unit of time by a star, galaxy, or other celestial object is referred to as luminosity in astronomy.

Answer:
h = 4 in
Explanation:
GIVEN DATA:
volume of tin
we know that
volume of cylinder is 
so,
construct formula for surface area
minimize the function wrt h
solving for h we have
![h = [\frac{4 v}{\pi}]^{1/3}](https://tex.z-dn.net/?f=h%20%3D%20%5B%5Cfrac%7B4%20v%7D%7B%5Cpi%7D%5D%5E%7B1%2F3%7D)
we kow 
so
h = 4 in
PV = 400 x 0.08 = 32 J
