a fixed pulley is a pulley attached to a support.
It is a line segment.
true
A sphere
A line in 2D and a plane in 3D A perpendicular bisector of the line connecting the 2 given points
It is the locus of all points such that their distance from a fixed line (the directrix) is the same as their distance from a fixed point which is not on that line (the focus).
Yes an elevator is a movable pulley!
a fixed pulley is a pulley that stays at one place to pick up an object. A clothes hanger is a fixed pulley.....this is all i know good luck...
Not all of it. There is a slightly movable joint between the two public bones.
It is a line segment.
The center of the circle. That's how the circle is defined. (The collection of all points on a plane equidistant from a fixed point. The fixed point is the center and the fixed distance is the radius.)
A single sheeve pully has only one wheel a multiple sheeve pully has more than one wheel.
triangle
A point. In fact it is fixed point and the locus of all points, in a plane that is a fixed distance from that fixed point defines the circle.
an ellipse.
That's false
circle
A set of all points is how various shapes are made in geometry. Lines are sets of points, and so are surfaces. Circles are sets of all points that are a fixed distance from a central point. All geometric shapes are made from sets of all points.
