A man cleaning his apartment pushes a vacuum cleaner with a force of magnitude 84.5 N. The force makes an angle of 33.9 ◦ with t
Sav [38]

Answer:

183.75641 Joules

Explanation:

F = Force of the vacuum cleaner = 84.5 N

s = Displacement of the vacuum cleaner = 2.62 m

\theta = Angle the force makes with the horizontal = 33.9°

Work done is given by

W=F\times scos\theta\\\Rightarrow W=84.5\times 2.62\times cos33.9\\\Rightarrow W=183.75641\ J

The work done by the force of the vacuum cleaner is 183.75641 Joules

At a certain location, wind is blowing steadily at 10 m/s. Determine the mechanical energy of air per unit mass and the power ge
Effectus [21]

Answer:

X=3976.078202kW \approx 3976kW

Explanation:

From the question we are told that

Wind speedV_w=10m/s

Turbine blade diameter D=90m

Air density  \tau=1.25kg/m^3

Mechanical energy K.E =0.05kJ/kg

Generally the power generation potential of the wind turbine X is mathematically given as

  X=m'*K.E

Where

m'=\tau *\pi*D^2/4*V

m'=1.25 *\pi*90^2/4*10

m'=79521.56404kg/s \approx 79521.5kg/s

Therefore

X=m'*K.E

X=79521.56404*0.05

X=3976.078202kW \approx 3976kW

X=4.0MW
