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 type of lens is in the eyepiece of a reflecting telecope?
Concave lens.
Can a Concave lens be use as an eyepiece in a microscope?
Concave lenses are used in the eyepieces of microscopes. However, they are not used alone on the eyepiece, but are joined in a concave-convex combination to prevent internal reflections.
If Jane is myopic. Will she need concave or convex lenses explain?
Concave. With myopia, the focal point of the eye is in front of the retina. Concave lenses increase the distance of the focal point so that it lies on the surface of the retina.
Is a red blood cell a regular shape?
A red blood cell is a specially adapted cell to help aid maximum absorption of oxygen needed for respiration. In relation to your question, red blood cells (or RBCs) are bi-concave shaped. Their bi-concave shape aids in their absorption of oxygen by increasing the cell's surface area. RBCs are also specially adapted in the way that they have no nucleus - again to fulfil the same function.
Why concave mirror is used for shaving?
Some people use concave mirror because when a man stands between the principal focus and pole of a concave mirror,he sees an enlarged,erect and virtual image of his face.this is the reason why a concave mirror of large focal length is used for shaving. concave mirrors concentrate on one focus and while shaving it concentrate on a point and the image is enlarge which prevents the face from cutting. because when a man stands between the pricipal focus and pole of a concave mirror , he sees enlarged ,erect and virtual image of his face .that is why concave mirror of large focal length is used for shaving
Why is the ppf concave to the origin?
because it has increasing opportunity costs
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.
What does concave lenses do to light rays?
a concave lens diverges the light ray travelling in a straight parallel path.
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.
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)
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.
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 is an imaginary straight line drawn perpendicular to a concave mirror at its center?
It's an Optical Axis.
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.
What is a concave m polygon?
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).
