Answer:
Night vision is the ability to see in low-light conditions. Whether by biological or technological means, night vision is made possible by a combination of two approaches: sufficient spectral range, and sufficient intensity range.

Answer
70 m/s, 140 m/s, 28 m/s²
Explanation:
Average velocity = total distance travel / time = 350 / 5 = 70 m/s
average velocity = (initial velocity + final velocity) / 2
70 × 2 = 140 m/s
change in velocity = final velocity - initial velocity = 140 m/s - 0 = 140 m/s
acceleration = (final velocity - initial velocity) / t = 140 m/s / 5 = 28 m/s²
Answer:
<em>Their displacement is 5 Km from the cabin.</em>
Explanation:
The displacement is define is the shortest distance between two points. It is the shortest distance of a line that joins two points together. It quantifies both the distance and direction of the net or total motion along a straight line from the initial position to the final position of the point trajectory. In this case, the straight line joining the cabin to the stream is line S which is equal to 5 Km
Explanation:
Question 9 A machine is applying a torque to rotationally accelerate a metal disk during a manufacturing process. An engineer is using a graph of torque as a function of time to determine how much the disk's angular speed increases during the process The graph of torque as a function of time starts at an initial torque value and is a straight line with positive slope. What aspect of the graph and possibly other quantities must be used to calculate how much the disk's angular speed increases during the process? The slope of the graph multiplied by the disk's radius will equal the change in angular speed The area under the graph multiplied by the disk's radius will equal the change in angular speed. The slope of the graph divided by the disk's rotational inertia will equal the change in angular speed. The area under the graph divided by the disk's rotational inertia will equal the change in angular speed. The area under the graph multiplied by the disk's rotational inertia will equal the change in angular speed E
