The difference in kilowatt-hours of monthly energy production between an average local wind speed of 15 miles per hour and an average local wind speed of 10 miles per hour is 5 miles per hour.

Energy production refers to how a lot of number one power a country extracts from nature. that is the whole of all of the harvested number one fuels and number one energy flows. word manufacturing ignores both imports and exports, and sums up what's extracted from nature.

In modern-day wind generators, wind rotates the rotor blades, which convert kinetic energy into rotational energy. This rotational power is transferred with the aid of a shaft to the generator, thereby producing electrical power.

Calculation:-

local wind speed of 15 miles per hour.

an average local wind speed of 10 miles per hour.

Therefore difference = 15 - 10

To known the speed and inertia of the cart.

What is inertia?

Matter has an attribute called inertia that makes it resist changes in velocity (speed and/or direction). Newton's first law of motion states that an object moving at a certain speed will stay there unless it is acted upon by an outside force.

What constitutes speed?

The speed of a change in an object's position in any direction Speed is defined as the ratio of distance to the amount of time it takes to cover that distance. Due to its lack of magnitude and only having a direction, speed is a scalar quantity.

Inertia of a cart is only dependent on the mass of the cart .

Mass of the cart , M = 12 Kg  is moving at speed 0.25 m/s  , speed of the cart is tripled but mass remains same , so that means inertia of the cart will be unchanged.

The gravitational force is reduced by a factor of 4 and the distance between two objects is doubled when the radius between them is increased by a factor of 2.

The gravitational force attracts mass-containing objects to one another. We frequently reflect on the gravitational pull of the Earth. This force keeps your body rooted to the ground. In light of the fact that the gravitational force is inversely proportional to the mass of the two interacting objects, heavier objects will be drawn by stronger gravitational forces. The gravitational pull between two objects therefore increases as their relative masses do.
