Identify the number of and types of elements in this schematic diagram
Nataly_w [17]
-- The long line and short line close together at the left side
       of the diagram represent a single-cell battery.
It's the only one in this diagram. 
It's a device that stores chemical energy and delivers it on demand.

-- The zig-zag lines with circles around them represent light bulbs.
There are three of them in this diagram. 
They are devices used to produce light by dissipating electrical energy.

-- The zig-zag lines without circles, at the top of the diagram,
       represent resistors.
There are two of them in this diagram.
They are devices used to change or control electrical parameters
   within a circuit by dissipating electrical energy.

-- The short straight line between two small circles at the bottom
       of the diagram  represents a switch.
There is only one switch in this circuit.
It's a device used to easily and quickly start or stop the flow of current
    past a certain point in a circuit.

In this circuit ...

-- When the switch is closed (as drawn), the light bulb nearest the battery
glows brightest, the light bulb in the middle glows less bright, and the light
bulb on the right side glows dimmest of all.

-- When the switch is open, the light bulb nearest the battery glows, and
neither of the other two light bulbs glows at all.

sertanlavr [38]

\textbf{Use equation of momentum}

p=mv

\text{momentum\ =\ mass x velocity}

\textbf{Substitute in the values}

5000 \times 75 = 375,000 \text{\ kg\ km/hr}

4200 \times 75 = 315,000 \text{\ kg\ km/hr}

\textbf{The\ small\ sports\ car\ will\ have\ the\ most\ momentum.}
