    A limit to the distance over which telepresence is practical is imposed by

    • A.

      The speed of EM wave propagation

    • B.

      The image resolution of the vision system

    • C.

      The ability of a robot to determine texture

    • D.

      All of the above

    Correct Answer
    A. The speed of EM wave propagation
    Explanation
    The correct answer is the speed of EM wave propagation. This is because telepresence involves transmitting and receiving signals over a distance to create a sense of being present in a remote location. The speed of electromagnetic wave propagation determines the time it takes for these signals to travel from one location to another. If the speed is too slow, it would result in significant delays and make telepresence impractical. Therefore, the speed of EM wave propagation is a limiting factor in the practicality of telepresence.

    Correct Answer
    B. Takes place in a single geometric plane
    Explanation
    Two-dimensional range plotting refers to the process of representing data or points on a graph with two axes. In this case, the correct answer states that it takes place in a single geometric plane. This means that the plotting is done on a flat surface, with one axis representing the horizontal direction and the other axis representing the vertical direction. The term "geometric plane" refers to a two-dimensional space that extends infinitely in all directions. Therefore, the correct answer implies that the range plotting is done on a two-dimensional graph without any curvature or three-dimensional aspects involved.

    Spherical coordinates can uniquely define the position of a point in up to

    • A.

      One dimension

    • B.

      Two dimensions

    • C.

      Three dimensions

    • D.

      Four dimensions

    Correct Answer
    C. Three dimensions
    Explanation
    Spherical coordinates consist of three components: a radial distance from the origin, an azimuthal angle, and a polar angle. These three components together uniquely define the position of a point in three-dimensional space. The radial distance determines how far the point is from the origin, the azimuthal angle determines the point's position around the origin in a horizontal plane, and the polar angle determines the point's position above or below the horizontal plane. Therefore, spherical coordinates can accurately describe the position of a point in three dimensions.
