<span>Speed is the distance traveled divided by the time it took to travel this distance. Velocity is the change in position divided by the time of travel. Velocity only depends on the starting and ending point but the speed depends on the path. Speed is a scalar quantity (the distance per time ratio) and velocity is a vector quantuty, because it is defined also with its direction.</span>

Explain radiation and which is the hotest source in the world
alexandr1967 [171]

Ramsar has the highest level of natural radiation in the world.

Hot springs located in the Arkaroola Wilderness Sanctuary in Southern Australia are also credited with higher than normal radiation levels, due to spring water coming in contact with rocks rich in uranium and radon.

(PLEASE HELP!!) Identify two types of motion where an object's speed remains the same while it continues to change direction.
hodyreva [135]
The 2 types of motions would be linear motion. Linear motion follows a straight linear path. Rotatory motion is also another type of motion. A rotatory motion is a motion along a curved path that may be planar or in 3 directions.

When you see a flat line on a position vs. time graph, what is the slope of this line? What does this tell you about motion of t
qwelly [4]

Answer:

The slope of the line is zero

The object is at rest

Explanation:

The graph position vs time of an object represents the position of the object measured at different times.

The slope of this graph is given by:

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

where

\Delta y is the increment in the y-variable

\Delta t is the increment in the x-variable

However, we have that:

\Delta y corresponds to \Delta r, the change in position of the object

\Delta x corresponds to the change in time, \Delta t

Therefore, for a position-time graph the slope of the graph corresponds to the velocity of the object:

m=\frac{\Delta r}{\Delta t}=v

An object having a flat line on a position-time graph has a line with slope zero: therefore, its velocity is zero, and this means the object is at rest.
