Where do the "conversion losses" shown in Figure 7.1 come from?
What will be an ideal response?
No real process is 100% efficient. This inefficiency is the source of such
conversion losses.

A substance is allowed to diffuse along a 10-cm length of tubing filled with water. The cross section of the tube is 5.3 cm2 . If the diffusion coefficient is 5.0 × 10^¯10 m2/s, and 6.5 × 10^¯14 kg is transported along the tube in 16 s, what is the difference in the concentration levels of the substance at the two ends of the tube?
a. 3.9E–1 kg/m3 b. 4.3E–2 kg/m3 c. 1.5E–3 kg/m3 d. 8.1E–4 kg/m3

A) the light will reach the front of the rocket at the same instant that it reaches the back of the rocket. B) the light will reach the front of the rocket before it reaches the back of the rocket. C) the light will reach the front of the rocket after it reaches the back of the rocket.
That quasars were at cosmological distances yet appeared like ordinary faint stars meant
