Density is mass per unit volume.
Answer:
Explanation:
The east vector is 10cos45 = 7.07 km
The north vector is 10sin45 - 10 = -2.93 km
The displacement magnitude is
d = √(7.07² + 2.93²) = 7.65... = 8 km
θ = arctan(-2.93/7.07) = -22.51... = 23° south of east.
Mechanical efficiency is a measure of how well the machine converts the input work or energy into some useful output. It is calculated by dividing the output work by the input work. The ideal machine has mechanical efficiency equal to unity, while the real machine has mechanical efficiency less than unity

Answer:
d. all of the above (a through c)
Explanation:
Photographic film, Photographic plates and a charged couple device all have longer integration time than the human eye.
The eye optimizes the time interval during which light energy is accumulated until a picture is sent to the brain. This interval is called the "time of integration" and is typically 0.1 sec; for low-light levels, it increases to perhaps 0.2 sec.
