Externally applied mechanical forces acting on a body, such as normal and shear forces, will cause deformation dependent on the
characteristics of that body and the magnitudes of the applied forces. Similarly, changes in temperature can cause deformation (i.e., expansion or contraction) as particles and bonds inside the material undergo changes in energy. For simple geometries, the changes in volume are proportional in the linear dimensions. Each of the 25cm×5cm25cm×5cm beams below is subjected to a 20 degree change in temperature. Rank the items based on the total change in length along the long axis of the beams. Many polymers such as polyethylene are significantly affected by changes in temperature, especially when compared to the metal and mineral materials discussed here. To a lesser degree, soft metals likewise are significantly affected by temperature changes. For example when heated, lead expands almost a third more than aluminum and almost twice as much gold. However, hard metals and materials, such as platinum and quartz, do not deform significantly in response to temperature. Because platinum is a metal, it will deform almost nine times more than quartz.

Answer:
Amount spent after sales tax = $112.58
Step-by-step explanation:
Given that:
Cost of jacket = $49.00
Cost of new Vans = $55.00
Total spent = 49.00 + 55.00 = $104.00
Sales tax = 8.25%
Amount of sales tax =
Amount of sales tax = $8.58
Total after sales tax = 104.00 + 8.58 = $112.58
Hence,
Amount spent after sales tax = $112.58
<h2>Hello!</h2>
The answer is:
B.
From the statement we know that the cheetah can reach a speed of 70 mph, but it can be maintained for no more than 1,640 feet.
The expression "no more than" means that at least it can be reached but never exceeded, it involves that the distance can be less or equal than 1,640 feet but never more than that.
So, the correct option is:
B.
Have a nice day!
