$1.$ An anemometer mounted at a height of $10$ m above a surface with crops, hedges, and shrubs showsa wind speed of $5$ m$/$s$.$ Assume $15\backslash$deg C and $1$ atm of pressure.a$.$ Estimate the wind speed and the specific power in the wind at a height of $120$ m$.$b$.$ A wind turbine with $80$ m rotor diameter is mounted with its hub at $80$ m above a groundsurface that is characterized by shrubs and hedges. Estimate the ratio of specific power inthe wind at the highest point that a rotor blade tip reaches to the lowest point that it falls to$.$
