To find:
Which type of mechanical wave is a water wave?
Explanation:
The water wave is a combination of longitudinal and transverse waves. They are a type of wave called surface waves. The surface waves are the waves that transmit energy in the interface between two mediums.
Final answer:
Thus the correct answer is option C.
There’s 10mm in a cm: 22mm
Answer:
a. 
b. 
c. 
Explanation:
Given:
- temperature of the hotter reservoir,
- temperature of the colder reservoir,
- heat absorbed by the engine,
- heat rejected to the cold reservoir,
- time duration of the energy transfer,
<u>Now the work done by the engine:</u>
Using energy conservation,
a.
<u>Hence the power output:</u>
b.
c.
now actual efficiency:
On the Newtonian theory of gravity, gravitation affects anything with mass. Assuming that none of the answer choices is the only thing that exists in the universe, all of the answer choices are subject to the law of universal gravitation (hence “universal”).
Satellites, water, frogs, and stars all have mass as they are all composed of matter. Thus, all four answer choices should be circled.
