The answer is A & B
A) The percent values were written incorrectly in the equation.
B) The amount of 7% solution should be written as 1 – x, not x – 1.
Hmm...
dam power plant (not sure if this is considered renewable): benefits: as it creates a tourist spot bringing more money and provides electricity.
disadvantages: restricts flow of water to farms, costs millions to build.
solar power plant: benefits: sunlight just keeps coming, produces a lot of electricity for maybe half the cost.
disadvantages: takes a large crew to maintain, mostly needs to be in an open area.
Wind farm: benefits: wind we don't have to worry about much, just blows through and turns the turbines, and can produce electricity almost 24/7.
disadvantages: unsightly, needs open space and costs a lot to build
Take your pick!
Answer: Hydrostatic equilibrium in the Sun means that pressure balances the weight of overlying layers.
Explanation: To find the answer, we have to know more about the Hydrostatic equilibrium in sun.
<h3>What is
Hydrostatic equilibrium in sun?</h3>
- Hydrostatic equilibrium in sun means that, the sun is neither expanding not contracting.
- We can say that the forces that control the sun are precisely balanced.
- The structure of the sun is in such a way that it can balance the pressure outward and the force of gravity inward.
- This balance is known as hydrostatic equilibrium.
Thus, we can conclude that, the Hydrostatic equilibrium in the Sun means that pressure balances the weight of overlying layers.

Answer:
v₂ = 16 m/s
Explanation:
We can use the continuity equation, which is as follows:
where,
A₁ = Area of inlet = πd²/4
A₂ = Area of outlet = π(d/2)²/4 = πd²/16
v₁ = velocity at inlet = 4 m/s
v₂ = velocity at outlet = ?
Therefore,
<u>v₂ = 16 m/s</u>
