What else can I help you with?
How do you draw a standing wave and label the nodes and antinodes?
To draw a standing wave, first sketch a wave with fixed boundaries at both ends, then add points where the wave amplitude is always zero (nodes) and points where the amplitude is at a maximum (antinodes). Nodes occur at the fixed ends and every half-wavelength in between, while antinodes appear at every quarter-wavelength in between. Label these points accordingly on your drawing.
Is a clothesline a fixed or movable pulley?
A clothesline can be a simple line strung between to upright fixed points, or it can be woven through a pulley system to allow the user to stand at a fixed position to use it.
What is the difference between a beam fixed at both ends and a cantilever beam?
A cantilever has only one end or point fixed; this is an obvious difference between having two points or both ends fixed. The nature of bending moment is same throughout the span in the case of a cantilever beam whereas a fixed beam has both types of nature, i.e. sagging as well as hogging.
What happens to all the points in a rigid body when it rotates about a fixed axis?
When a rigid body rotates about a fixed axis, all the points in the body move in circular paths around that axis.
What is true about nodes and antinodes of a standing wave?
Nodes are points in a standing wave that have zero displacement, while antinodes are points that have maximum displacement. Nodes occur at fixed points where the wave pattern crosses the equilibrium position, while antinodes occur at points halfway between nodes where the wave amplitude is largest.
What is the set of two fixed points and all points in between them?
It is a line segment.
Which two fixed points define the shape of a hyperbola?
the foci (2 focal points) and the distance between the vertices.
How does Asynchronous Transfer Mode ATM transmit data?
As fixed-size cells via a fixed channel between two points
What term best describes the set of all points in a plane for which the sum of the distances two fixed points equal a certain constant?
You're trying to describe an "ellipse".
How you find fixed points of a function?
The fixed points of a function f(x) are the points where f(x)= x.
What is the difference between segment and line?
A segment only goes between 2 fixed points where a line goes on indefinitely
What is the set of points in a plane that are equal distant from a fixed point called?
A set of points in a plan that are equally distanced from a fixed point is called a circle. equation of a circle is: (x - h)2 + (y - k)2 = r2 Center = (h, k) Radius = r Since Radius (can vary for different circles on that plan) is at equal distance throughout the plan we can therefore say that a set of points in a plan that are equally distanced from a fixed point is called a circle.
What info do you need to find an object's speed?
You would need to know the distance travelled between two fixed points and the time taken to travel between those two points.
Which term best describes the set of all points in a plane for which the sum of the distance to two fixed points equals a certain constant?
The term that best describes the set of all points in a plane for which the sum of the distances to two fixed points equals a certain constant is an "ellipse." In this context, the two fixed points are called the foci of the ellipse, and the constant represents the total distance from any point on the ellipse to these two foci. If the constant is less than the distance between the foci, no points will satisfy the condition, and if it equals the distance between the foci, the ellipse degenerates into a line segment connecting the two points.
Is there a fixed relationship between a incident ray and a reflected ray?
Yes. The angle of incidence and reflection are equal.
What is the way to figure out degrees?
A degree is usually a division of a measure between two fixed points. Sometimes, as in the case of temperature scales, it is between two arbitrary points. In others, such as angular displacement, it is a subdivision of a turn.
Briefly explain the focus and directrix of a parabola?
the set of points equidistant from a fixed point
