Answer:
A) 1384.6 J/g
b)110.768 MJ
Explanation:
Given data:
density of titanium = 4.5 g/cm^3
specific heat = 0.544 J/g degree C
heat of fusion = 419 J/g
Pouring temperature for titanium = 1800 degree C
Initial temperature = 25 degree C
a) eneegy for heating unit mass is given as
= 1384.6 J/g
b) Total energy to heat 80 kg metal
we know for one unit 1384.6 J/g energy is required
therefore for 80 kg , energy required is
= 110768000 J
Answer:
Attached is the complete question but the weight of the mailbox and cross bar differs from the given values which are : weight of mail box = 3.2 Ib, weight of the uniform cross member = 10.3 Ib
Answer : moment of inertia = 186.7 Ib - in
Explanation:
Given data
weight of the mailbox = 3.2 Ib
weight of the uniform cross member = 10.3 Ib
The origin is of mailbox and cross member is 0
The perpendicular distance from Y axis of centroid of the mailbox
= 4 + (25/2) = 16.5"
The centroid of the bar =( ( 1 + 25 + 4 + 4 ) / 2 ) - 4 = 13"
therefore The moment of Inertia( Mo) = (3.2 * 16.5) + ( 10.3 * 13)
= 52.8 + 133.9 = 186.7 Ib-in
Pipelines are a useful means of transporting oil because they offer low maintenance and dependable transportation for a narrow but important range of products.
<h3>What is a pipeline?</h3>
A pipeline is a system of connected pipelines that can be either underground or out in the environment. These pipelines are used to transport or distribute water, gas, and oil.
The options are attached
a. Pipelines provide jobs for consumers because of the resurgence of exploration and drilling in North America.
b. Pipelines are versatile, carrying more ton-miles than any other mode of transport over more than 2 million miles of pipeline.
c. Pipelines have more locations than water carriers.
d. Pipelines offer low maintenance and dependable transportation for a narrow but important range of products.
Thus, the correct option is d. Pipelines offer low maintenance and dependable transportation for a narrow but important range of products.

Answer: 4I
Explanation:
If we had simply put in parallel with the wire one equal to it, the total current flowing through both resistors would double, due to the equivalent resistance of two resistors of equal value, in parallel, is just the half of one of them, so applying Ohm's Law, I will be double than I₀.
But in this case, everything happens as if we put in parallel two resistors of half the value (as the resistance is directly proportional to the length while Ohm's Law be valid), so the equivalent resistance becomes 1/4 of the original wire.
Applying Ohm's Law, we have I = (V / R/4) ⇒ I = 4 I₀
Answer:
the elevation at point X is 2152.72 ft
Explanation:
given data
elev = 2156.77 ft
BS = 2.67 ft
FS = 6.72 ft
solution
first we get here height of instrument that is
H.I = elev + BS ..............1
put here value
H.I = 2156.77 ft + 2.67 ft
H.I = 2159.44 ft
and
Elevation at point (x) will be
point (x) = H.I - FS .............2
point (x) = 2159.44 ft - 6.72 ft
point (x) = 2152.72 ft
