Question

a turbine cannot be rotated by

1.Flowing water
2.Heat of sun
3.Steam
4.Moving wind​

Answer 1

Explanation:

So turbine now has a fixed kinetic energy. But once you connect load(say a light bulb)you will notice that the turbine will stop rotating

Answer 2

Answer is - Heat of sun

From massive wind farms generating power to small turbines powering a single home, wind turbines around the globe generate clean electricity for a variety of power needs.

Explanation:

In the United States, wind turbines are becoming a common sight. Since the turn of the century, total U.S. wind power capacity has increased more than 24-fold. Currently, there’s enough wind power capacity in the U.S. to generate enough electricity to power more than 15 million homes, helping pave the way to a clean energy future.

WHAT IS A WIND TURBINE?

The concept of harnessing wind energy to generate mechanical power goes back for millennia. As early as 5000 B.C., Egyptians used wind energy to propel boats along the Nile River. American colonists relied on windmills to grind grain, pump water and cut wood at sawmills. Today’s wind turbines are the windmill’s modern equivalent -- converting the kinetic energy in wind into clean, renewable electricity.
