Higher wind speeds would increase the amount of electricity generated by a wind turbine.
<h3>What is a power plant?</h3>
A power plant is an industrial structure that generates electricity. The majority of power plants are linked to the electrical grid.
Stronger winds produce greater power because they enable the blades to revolve more quickly. Greater mechanical and electrical power from the generator result from faster spinning.
Hence, higher wind speeds would increase the amount of electricity generated by a wind turbine.

Answer: Option D and E
Explanation: Across the electromagnet spectrum, the frequency increases but the wavelength reduces.
This implies that radio waves have the longest wavelength but the smallest frequency, while gamma rays have the shortest wavelength but the highest frequency.
This implies that there is an inverse relationship between wavelength and frequency.
Of all the technologies listed above, wireless internet has the highest frequency hence making it have the shortest wavelength.
Also by comparing values from the data given to us above, it is possible for some wireless internet device to operate within the same frequency range of the microwave.
Focusing on the present is a characteristic of the observant function.
<h3>What is an Observant personality trait?</h3>
This trait is characterized by people who pay much attention to themselves more than others.
This type of people focus on the present and ensure things are done without procrastination. This depicts the option D which makes it the most appropriate choice.

Answer:
m = 2.31 Kg
Explanation:
given,
m₁ is the mass rest on the inclined plane = 1.5 Kg
inclination of plane = 30°
Kinetic friction = μ = 0.4
acceleration of the body = 2.68 m/s²
mass m is hanging = ?
using equation to solve
T - m₁g sin θ - μ m₁g cos θ = m₁ a
on the block on inclined plane there will be acting tension T on the string,
mg sin θ will be the force acting opposite to the tension on the string and a frictional force will be acting which will oppose moment which will be equal to μ m₁g cos θ
T = m₁(g sin θ + μ g cos θ + a )
T = 1.5 (9.8 x sin 30° + 0.4 x 9.8 x cos 30°+ 2.68 )
T = 16.46 N
now, forces on the other side of pulley
m g - T = m a
m (g - a ) = T
m = 2.31 Kg
I will assume here that the well is sufficiently short so that the time the sound takes to come from the bottom of the well to our ear is negligible.
Since the pebble moves by uniformly accelerated motion, the distance it covers is given by
where
is the gravitational acceleration
is the time the pebble takes to reach the bottom of the well
Therefore, the depth of the well is
and the correct answer is B.
