When building a bridge, engineers want the bridge cables to have great:
- Tensile strength has to do with the amount of stress that a thing is able to resist without breaking under legthwise stress.
- This is measured by the largest load (kg) per unit area as it refers to the amount of stress an object or material is <u>able to endure</u> without tearing apart or breaking off.
- As a result of this, when building a bridge, engineers want the bridge cables to have great tensile strength so that they do not collapse <em>under the weight</em> placed on them.
- A bridge is a passage or structure that <em>connects between two obstacles.</em> A lot of cars, heavy lorries and trucks pass through a bridge, so iit is important that the bridge cables are able to resist this stress effectively.
'
- Therefore, the correct answer is tensile strength

The equation to use:
Change in energy = mass x SHC x change in temperature
Energy = 0.02 x 0.450 x 26
= 0.234 J
In the combined gas equation, (P1V1)/T1=(P2V2)T2, where P1 is the initial pressure, V1 the initial volume, T1 the initial temperature,P2 is the final pressure, V2 the final volume, T2 the final temperature,
substituting for the values: (155kPa× 1.00L)/273K=(500kPA× V2)/408K
V2=(155kPa×1.00L×408K)/(273K×500kPa)
= 0.463L
Answer:
B
Explanation:
Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface.
