I would say C: Dam
Sea walls and levees stop water from overflowing onto something. Which can we good but has no impact on droughts.
Storm shelters wont impact droughts either. They are men't to protect people from storms.
A Dam on the other hand can contain and keep water in one given place. Which will save water, to be used to prevent future droughts.
Hope this helps!
Brainliest is appreciated if you feel its deserved!
Answer:
Explanation:
Work: This can be defined as the product of force and distance. The unit of work is Joules (J). it can be expressed mathematically as
W = F×d
or
W =
.................................. Equation 1
Where b = upper limit, a = lower limit, Fx = expression of force.
<em>Given: a = 0 , b = 1.3 m, Fx = 4 + 15.7x - 1.5x²</em>
Substituting these values into equation 1
<em>W =
</em>
W = ᵇ[4x + 15.7x²/2-1.5x³/3 +C]ₐ
Work = upper limit - lower limit
Work = ᵃ[4x + 15.7x²/2 - 1.5x³/3 +C] - [4x + 15.7x²/2 + 1.5x³/3 +C]ᵇ............... Equation 2
Substituting the values of a and b into equation 2
Work = [4(1.3) + 15.7(1.3)²/2-1.5(1.3)³/3 + C] - [0 +C]
Work = [5.2 + 26.53 -3.29 + C] - C
Work = 28.44 J
Work done by the force = 28.44 J.
Answer: False but read why
Heated water molecules expands ( become less dense) but they do float to the top.
Low pressure has a bit less of a function than high pressure, high pressure is more useful in certain terms
