Explanation:
The ratio of the areas is the square of the ratio of the radii.
A/A = 3.16² = 9.99
The ratio of the volumes is the cube of the ratio of the radii.
V/V = 3.16³ = 31.6
This can be seen as a trick question because heat engines can typically never be 100 percent efficient. This is due to the presence of inefficiencies such as friction and heat loss to the environment. Even the best heat engines can only go up to around 50% efficiency.
<u>Answer:</u>
The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
<u>Explanation:</u>
*can i be the brainliest*
A) F = gravitational force
b) G = universal gravitational constant (6.67 × 10-11 N-m2/kg2)
c) m1 = mass of the body 1
d) m2 = mass of body 2
e) r = radius or distance between the two bodies.
Hope this helps!
