A. How much work is being done to hold the beam in place?
Work is the product of Force and Displacement. Since there
is no Displacement involved in just holding the beam in place, hence the work
is zero.
B. How much work was done to lift the beam?
In this case, force is simply equal to weight or mass
times gravity. Hence the work is:
Work = weight * displacement
Work = 500 lbf * 100 ft
Work = 50,000 lbf * ft
C. How much work would it take if the steel beam were
raised from 100 ft to 200ft?
The displacement is still 100 ft since 200 – 100 = 100 ft,
hence the work done is still similar in B which is:
<span>Work = 50,000 lbf * ft</span>
Answer:
The answer is 20 miles
Explanation:
You would use a^2+b^2=c^2 to get the displacement.
So 16^2+12^2=c^2
400=c^2
c=20
A would be the best answer beacuse
Ovaries - small, oval-shaped glands that are located on either side of the uterus. The ovaries produce eggs (ova - an ovum is one egg, ova means multiple eggs.) The ovaries also produce the main female sex hormones which are released into the bloodstream.
Explanation:
The difference between a seismograph and a Seismogram is that:
a Seismograph is referred to a tool or instrument used in measuring the magnitude or effect of an earth quake
While
Seismogram is a type of output report or data that is generated out of a seismograph.
So in summary, a Seismograph is an instrument or tool while Seismogram is an output data generated from the usage of a seismograph.
Given:
1 mi = 1609 m.
Also,
1 hour = 3600 s
Therefore
Answer: 767.4 mph (nearest tenth)
