ale4655 [162]

The correct option is 0.5 M

Calculation

Wavelength is defined as the ratio of velocity of a wave to its frequency. It is measure in meters. Mathematically, wavelength is given by the following formula:

Wavelength = wave velocity / frequency

From the details given in the question,

Wavelength =?

Velocity = 340 m/s

Frequency = 680 HZ

Wavelength = 340 /680 = 0.5

Therefore, wavelength = 0.5 M

A car has the velocity of 2.35 after 4.67 it's velocity is 9.89 what is the average acceleration
kiruha [24]
Average acceleration  =  (change in speed) / (time for the change) .
  
Change in speed = (ending speed) - (beginning speed)

                       =  (9.89 miles/hour) - (2.35 yards/second)  = 26,839.2 ft/hr

Acceleration  =  (26,839.2 ft/hr) / (4.67 days)  =  2,873.58 inch/hour²

Explain the relationship between mass and acceleration
ycow [4]

Answer:

Explanation: Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

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
