On a speed-time graph, a horizontal line shows the change in speed is ____.

Physics

spayn [35]4 years ago
4 0

On a speed/time graph, the height of the line at any point
shows the speed at that moment.  If the line is horizontal,
then its height isn't changing, meaning that the speed isn't
changing.  It's constant.  The change is zero, until the line
starts rising or falling.

A steel ball moves from a position of +125 meters to a position of -75 meters. This motion takes 90.0 seconds. What is the veloc
bonufazy [111]

Answer:

2.22m/s to the left

Explanation:

Given parameters:

Initial position = +125m

Final position  = -75m

Motion time  = 90s

Unknown:

Velocity of the steel ball  = ?

Solution:

The velocity of the steel ball is given as the displacement divided by the time;

   Velocity  = \frac{displacement}{time}

The net displacement of the ball  = 125- (-75) = 200m to the left

Input the parameters and solve for the velocity;

     Velocity  = \frac{200}{90}   = 2.22m/s to the left

Why does the area around the equator stay about the same temperature year round?
Verdich [7]
Axial Tilt and Sun Energy

This axial tilt means that during the Earth's journey around the sun the poles receive varying amounts of sunlight. The equator, however, receives relatively consistent sunlight all year. The consistency of energy means the equator's temperature stays relatively constant all year.
