Aleks04 [339]
The answer is C) an electromagnetic wave

An electromagnetic wave, which includes electromagnetic radiation such as visible light, moves the fastest of all of the options listed by a significant margin, especially through space. In fact, light travelling through space is technically the theoretical limit of how fast something can travel.

An object is dropped from a height of 25 meters. At what velocity will it hit the ground?
Goryan [66]
You can use Vf^2-Vi^2 = 2ax

Vf^2 - 0 = 2(9.81)(25)

Or you can use energy

mgh = 1/2mv^2

2gh =v^2

What is a horizontal segment meaning on a position vs. time graph?
sergeinik [125]

The velocity of the object is zero (the object is at rest)

Explanation:

A position vs time graph represents the motion of an object; in particular:

  • The position of the object x(t) is represented on the y-axis
  • The time t is represented on the x-axis

For a position-time graph, the slope of the graph is given by

m=\frac{\Delta x}{\Delta t}

where

\Delta x is the change in position

\Delta t is the change in time

However, we see that this is equivalent to the definition of velocity:

v=\frac{\Delta x}{\Delta t}

Therefore, the slope of  a position-time graph is equivalent to the velocity of the object.

And so, a horizontal segment on a position vs time graph means that the object has zero velocity (because the slope is zero).
