a mobile base in an urban environment has the power of 15 microW at 175 m. If the propagation follows an inverse cube power law,
Evgen [1.6K]

Answer: Power P at distance 0.7 km is: 0.234 µW

Explanation:

We know that

inverse cube-power law.

Thus Power, P = c / d³

Substituting we have

15 µW = c / (175 m)³

c = (15 µW) x (175 m)³

Then finally Power value at 0.7 km.

Will be

P = c / d³

P = ((15 µW) x (175 m)³) / (700 m)³

= (15 µW) x (175 / 700)³

= (15 µW) x (0.25)³

=(15 µW) x (0.015625)

P = 0.234 µW

Explain the danger leaks pose when operating a tractor.
Romashka [77]
Read and follow procedures as outlined in the operator's manual. By being familiar with the operating features of a tractor, the operator will develop confidence when the tractor is driven under adverse conditions. Learn the location and purpose of all of the guages and controls as well as other indicators. Knowing where the controls are by memory can allow you to react more quickly in an emergency situation. There have been accident situations where individuals have become entangled in machinery or the power takeoff shaft and rescuers or family did not know how to disengage the equipment. Family members should be showed how to shut down equipment or disengage the PTO in case of emergency.
Study the various decals on your equipment. They may point out DANGER, WARNING and CAUTION for various points on the tractor. Have an experienced tractor operator with you as you review the various decals and ask questions!
