Why do you think the area swept out by a planet in a given period of time remains constant, even as the planet speeds up and slo
Levart [38]
Not sure this is entirely right but hey why not, right. <span> A planet orbiting a star orbits in an ellipse. Sometimes it's closer to the star and sometimes it's further. When it's closer to the star, the gravity on the planet from the star is stronger, so the planet speeds up. The area the planet sweeps over is equal because when it speeds up the length covered along the orbital path is greater, but it is also closer to the star, and that dimension is decreased. And because of our very intelligently designed and organized universe, these two factors cancel each other out perfectly </span>

What is the wavelength of the waves you create in a swimming pool if you splash your hand at a rate of 2.00 Hz and the waves pro
Valentin [98]

Answer:

The wavelength of the waves created in the swimming pool is 0.4 m

Explanation:

Given;

frequency of the wave, f = 2 Hz

velocity of the wave, v = 0.8 m/s

The wavelength of the wave is given by;

λ = v / f

where;

λ is the wavelength

f is the frequency

v is the wavelength

λ = 0.8 / 2

λ = 0.4 m

Therefore, the wavelength of the waves created in the swimming pool is 0.4 m

a steam engine works on its vicinity and 285 k heat is released with the help of 225 degree centigrade energy absorbed to the sy
Studentka2010 [4]

The efficiency of the steam engine is 78.9%.

<h3>What is the efficiency of a machine?</h3>

The efficiency of a machine is a measure of the useful work done by the machine as against the work input into the machine.

  • Efficiency of a machine = work output/work input × 100%

Work output of the steam engine = 225 K

Work input of the steam engine = 285 K

The efficiency of the machine = 225/275 × 100% = 78.9%

Therefore, the efficiency of the steam engine is 78.9%.
