Acceleration can be found using a speed-time graph. select the best answer from the choices provided t f

False

Explanation:

Acceleration is defined as the rate of change of velocity:

On a speed-time graph, the slope of the curve gives the magnitude of the acceleration. In fact, the slope of the curve in a speed- time graph is

where

is the increment in the y-variable, so it corresponds to the change in speed

is the increment in the x-variable, so it corresponds to the change in time

so the slope corresponds to

which is the magnitude of the velocity. However, in order to define acceleration we need an additional piece of information: the direction. Since speed is a scalar, direction of motion is not provided, so we cannot fully define acceleration from a speed-time graph.

concave lenses are used here. they spread the light out before it reaches the convex lens in the eye, therefore letting the image focus directly on the retina. hyperopia is known to you probably as farsightedness.

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
