"Acceleration is increasing with time" tells us that the derivative of acceleration is positive. Since acceleration is the derivative of velocity, this means that the second derivative of velocity is positive. By definition, having a non-negative second derivative means that velocity is concave up.

∙ 14y agoIf acceleration is increasing with time, the velocity graph will be concave up. This is because a positive acceleration causes the velocity to increase over time, resulting in a curve that opens upward on the velocity-time graph.
concave mirror is a solar device
Yes, a concave lens can be used as an eyepiece in a microscope to help magnify the image being viewed. Concave lenses are often used to decrease the focal length and adjust the magnification of the microscope.
A concave mirror has a virtual focus. This is because the rays of light that are incident on a concave mirror are reflected and appear to diverge from a point behind the mirror, creating a virtual focus.
No,concave part face plasma membrane.Convex part face endoplasmic reticulumn.
If Jane is myopic (nearsighted), she will need concave lenses to correct her vision. Concave lenses help to diverge light rays before they enter the eye, bringing the focal point forward to the retina, which helps to focus distant objects clearly for someone with myopia.
On a position vs. time plot with constant acceleration, the graph would be a curved line, not a straight line. The curve would be concave upward if the acceleration is positive and concave downward if the acceleration is negative. The slope of the line would represent the velocity at any given time.
Positive acceleration occurs when an object is speeding up in the positive direction, meaning its velocity is increasing over time. This could be due to a force pushing the object in the positive direction, resulting in a positive rate of change of velocity.
because it has increasing opportunity costs
If the opportunity cost is constant, the PPF is a straight line; when the opp. cost of a good rises when it is produced more, then concave.
Many graphs that appear concave from one side will appear convex from the other. A smooth graph is generally described as concave if it is increasing AND if the rate of increase is also increasing. In terms of calculus this requires the first and second derivative to be positive. A concave polygon is one in which at least one of the vertices forms a reflex angle.
The Law of Increasing Opportunity Cost that is shown in a Production Possibilities Curve is concave to the origin. This is because it shows the maximum gain of two products used in production.
optical axis
In physics, 'concave up' refers to the shape of a curve or surface that opens upward, resembling a cup that faces upwards. This typically signifies a region where the rate of change of a function is increasing. It is often associated with the idea of a positive second derivative.
Formally, a polgon is concave if there is at least one pair of points in (or on) the polyhedron such that the straight line joining the two points is not wholly inside (or on) the polyhedron.In less formal terms, a concave polygon is one which has a bit going inwards.
I think it is niether * * * * * A heptagon is simply a plane shape bounded by seven straight sides. Any polygon with three of more sides can be concave or convex.
Because when one produces one product, the opportunity cost of the other product increases i.e. the concave represents the increasing opportunity cost with the production of a good.
A concave m polygon is a 2-dimensional shape which is bounded by m straight sides with at least one internal angle that is a reflex angle (greater than 180 deg).
