Hydroelectric plants use __________ to produce electricity. A. fire B. sunlight C. water D. wind
xz_007 [3.2K]
"Hydro..." means "water".  Hydroelectric plants use the kinetic energy
of falling water to produce electrical energy. 

I wouldn't exactly say that they "use water", because after they produce
the electrical energy, there's still just as much water as there was before.

Calculate the mass of air in a room if the floor dimensions are 10 mx
aleksklad [387]
  • <em>Answer:</em>

<em>604.8 kg</em>

  • <em>Explanation:</em>

<em>Hi there ! </em>

<em>d = m/V => m = d×V</em>

<em>V = l×w×h = 10m×12m×4m = 480 m³</em>

<em>m = 1.26kg/m³×480m³ = 604.8 kg</em>

<em>Good luck !</em>

There are two identical small metal spheres with charges 38.9 µC and −27.6399 µC. Thedistance between them is 6 cm. The spheres
Greeley [361]

Answer:

2683.3N

Explanation:

According to coulombs law which states that "the force of attraction existing between two charge q1 and q2 is directly proportional to the product of the charges and inversely proportional to the square of the distance (d) between them. Mathematically |F|= k|q1| |q2| /d² where;

F is the force of attraction between the charges

q1 and q2 are the charges

d is the distance between them

k is the coulombs constant

Given |q1|= 38.9 × 10^-6C and |q2| = 27.6399×10^-6C d = 6cm = 0.06m

k = 8.98755 × 109 Nm² /C²

Substituting the given data's in the equation we have;

|F| = 8.98755 × 10^9×38.9×10^-6×27.6399×10^-6/0.06²

|F| = 9.66/0.06²

|F| = 9.66/0.0036

|F| = 2683.3N

The magnitude of the force will be 2683.3N

Note that the modulus of the charges changes negative value of q2 to positive value. The opposite signs of the charges doesn't affect the final calculation, it only tells the force of attraction or repulsion between the charges. Since they are unlike charges, they will attract each other in the field.
