If the acceleration is increasing with time will the velocity graph be a straight line concave up or concave down?
Concave up.
"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.
What else can I help you with?
Why are concave mirrors used in solar cookers?
concave mirror is a solar device
Can a Concave lens be use as an eyepiece in a microscope?
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.
Does concave part of Golgi body faces nucleus?
No,concave part face plasma membrane.Convex part face endoplasmic reticulumn.
Which spherical mirror has a virtual focus-concave or convex?
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.
If Jane is myopic. Will she need concave or convex lenses explain?
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.
What would the graph look like on a position verse time plot with constant acceleration?
If the constant acceleration is positive, the graph would be an exponential (x2) graph. If there is constant acceleration, then velocity is always increasing, making the position change at an ever increasing rate.
Definition for positive acceleration?
Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)
What is the difference straight ppf and concave ppf?
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.
Why is the ppf concave to the origin?
because it has increasing opportunity costs
How does concave graph look like?
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.
Law of increasing opportunity costs reflected in a PPC is concave to the origin?
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.
What is the practical meaning of second derivative?
The second derivative of a function measures the rate of change of the first derivative, providing insight into the curvature or concavity of the function's graph. A positive second derivative indicates that the function is concave up (shaped like a cup), suggesting that the slope of the function is increasing. Conversely, a negative second derivative indicates concave down (shaped like a cap), where the slope is decreasing. In practical terms, this helps in understanding the acceleration of trends, such as acceleration in physics or the behavior of financial markets.
The straight line that is drawn perpendicular to the center of a concave or convex mirror is the?
optical axis
What is a concave polyhedron?
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.
Is a heptagon convex or concave?
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.
What does 'concave up' mean in physics terms?
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.
Explain why a production possibilities curve is concave?
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.
