Answer: Pros and cons okay
Explanation:
Pros: Produces no polluting gases. Waste is radioactive and safe disposal is very difficult and expensive.
Does not contribute to global warming.
Cons: Waste is radioactive and safe disposal is very difficult and expensive.
Local thermal pollution from wastewater affects marine life.
Answer:
is the minimum gap between the slabs
Explanation:
Given:
- length of the concrete highway,
- coefficient of thermal expansion,
- range of temperature variation,
<u>Now form the equation of thermal expansion:</u>
Since each slab of the highway expands by the above length so the minimum gap between the slabs to prevent buckling:
is the minimum gap between the slabs
Answer:
μ = 0.189
Explanation:
The spring potential energy will convert to work of friction
Fd = ½kx²
μmgd = ½kx²
μ = kx²/2mgd
μ = 167(0.132²) / (2(2.77)(9.81)(0.284))
μ = 0.18852424...
