Den pushes a desk 400 cm across the floor. He exerts a force of 10 N for 8 s to move the desk.

stellarik [79]

Answer: The correct option is Option b.

Explanation:

Power is defined as the rate of work done by an object.

Mathematically,

$P=\frac{W}{t}$ .....(1)

And work done is the product of force exerted on the object times the displacement covered by that object.

Mathematically,

$W=F.s$

Putting this value in above equation, we get:

$P=\frac{F.s}{t}$

where,

P = power = ?W

F = Force exerted = 10N

s = Displacement = 400cm = 4m (Conversion factor: 1m = 100 cm)

t = Time taken = 8s

Putting values in above equation, we get

$P=\frac{10\times 4}{8}\\\\P=5W$

Hence, the correct option is Option b.

Water flows over a section of niagara falls at the rate of 1.2x10^6 and falls 50.0 m. how much power is generated by the falling

iren [92.7K]

The solution for this is:

Power = Energy transferred / Time taken

Energy Transferred in one second ( Power) = mgh/s

= (1.2x10^6)(9.8)(50) = 588000000 J/s

Power = 588000000 W

Power is work done / time

Work done in one second = [ rate of fall of mass]

gh = 1.2* *9.81*50 x 10^6 J/s

= 5.886e+8 W

Explain what the ionosphere is and how it interacts with some radio waves.

kumpel [21]

Answer:

Explained

Explanation:

Ionosphere is the outermost layer of the Earth's atmosphere,extending from 60 km to 1,000 km altitude.
It mainly consists of ionized gases by the solar radiation.
It is very important layer to Earth because it influences the radio propagation to distant places on Earth.
Being ionized it reflects high frequency(shortwave) radio waves to the sky as well as to the Earth by a technique called "skip" or "skywave" propagation for the communication over long distances.
