Answer: It may be unreliable.

Explanation:

Harnessing wind a s a source of energy is very efficient and renewable. It does not produce any waste and is environment friendly energy resource because it is naturally occurring.

But it is unreliable. The wind is the motion of air from high pressure region to low pressure region. Thus, we cannot start or stop wind turbines to spin. It depends on the wind and its speed.

Hydroelectric dams use ------- to produce electricity. gravitational potential energy of falling water

Eduardwww [97]

Answer:

Gravitational potential energy

Explanation:

Hydroelectric dams are the power plants which generates electricity by using the energy of falling water from a great height.

A the water is stored in big reservoirs and at a great height, it contain lot of potential energy due to the height. As it falls downwards, the potential energy is converted into kinetic energy of the water. this kinetic energy of the falling water is used to run the turbine, and then the electric energy is generated.

So, in hydroelectric power stations, the potential energy of water is converted into the electric energy.

A chair of weight 70.0 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F =

Annette [7]

Answer:

94.67 N

Explanation:

Consider a free body diagram with force, F of 41 N applied at an angle of 37 degrees while the weight acts downwards. Resolving the force into vertical and horizontal components, we obtain a free body diagram attached.

At equilibrium, normal reaction is equal to the sum of the weight and the vertical component of the force applied. Applying the condition of equilibrium along the vertical direction.

$\begin{array}{l}\\\Sigma {F_y} = 0\\\\N - W - F\sin \theta = 0\\\\N = W + F\sin \theta \\\end{array}$

Substituting 70 N for W, 41 N for F and $\theta$ for 37 degrees

N=70+41sin37=94.67441595 N and rounding off to 2 decimal places

N=94.67 N
