Answer:
ydropower, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy
Explanation:
In the generation of hydroelectric power, water is collected or stored at a higher elevation and led downward through large pipes or tunnels (penstocks) to a lower elevation; the difference in these two elevations is known as the head. At the end of its passage down the pipes, the falling water causes turbines to rotate. The turbines in turn drive generators, which convert the turbines’ mechanical energy into electricity. Transformers are then used to convert the alternating voltage suitable for the generators to a higher voltage suitable for long-distance transmission. The structure that houses the turbines and generators, and into which the pipes or penstocks feed, is called the powerhouse.
The answer for the given question above would be option C. GRAVITATIONAL FORCE. Based on the given scenario above of a leaf that falls to the ground when Tonya let it go, the force that pulled the leaf to the ground is the gravitational force. This kind of force is a force <span>that attracts any object with mass. Hope this helps.</span>
Answer is at the very end
Explanation:
Given parameters:
Mass of the asteroid = 10 x 10⁹kg
Distance between the asteroid = 850km
Unknown:
Force = ?
Solution:
We can predict the outcome of this reduction in distance between the two masses using the newton's law of universal gravitation.
The law states that "the gravitational force of attraction between two masses is directly proportional to the product of their masses and inversely proportional to the square of the distances between them".
Mathematically, we have;
F =
F is the gravitational force
G is the universal gravitational constant = 6.67 x 10⁻¹¹Nm²kg⁻²
m is the mass of the body
r is the distance between them.
From this, we know that as the separation increases, the force of gravitation will reduce since the mass is constant.
The distance between the two asteroids decreased from 1000km to 850km, this will increase the force of attraction between them and we expect the force to be higher than 6700N.
At 1000Km, force = 6700N,
since as the distance reduces the force increases, we expect the force to be about 9200N.
Let us verify this by plugging the values into the equation:
F =
F = 9200N
Answer:
Reaction Range
Explanation:
Reaction Range defines the basic IQ of an individual based on both the Phenotype expressed by the Genotype of that organism as well as the external environmental factors.
