To develop the problem we will start by finding the energy taken by each cycle through the efficiency of the motor and the exhausted energy. Later the work will be found for the conservation of energy in which this is equivalent to the difference between the two calculated energy values. Finally the estimated time will be calculated with the work and the power given,
PART A)
Work done by the heat engine in each cycle = W
According to the value given we have that,
Power is defined as the variation of energy as a function of time therefore,
Therefore the interval for each cycle is 0.75s
Answer:
Explanation:
A wave is a phenomenon that travels through a material medium without any permanent effect on the medium. It can be classified as mechanical or electromagnetic waves. And the two major types are transverse and longitudinal.
From the given question;
1. Longitudinal waves e.g sound waves, waves in a spring'
2. Frequency (number of cycles per second).
3. Wavelength of the wave. Measured in meters.
4. Transverse waves e.g light waves, water waves.
5. Wave speed.
6. Electromagnetic waves e.g ultraviolet waves, X-rays etc.
7. Amplitude.
8. Hertz.
9. Rarefaction
10. Compression
A 'vector' is a measurement that has a magnitude and a direction.
For the vector given here, "<em>15 ft/s</em>" is the magnitude, and "down" is the direction.
Well you didnt give us any options to choose from
but my guess is that it has to do with erosion caused by the water
