## Estimate the order of magnitude of the length, in meters, of each of the following; (a) a mouse, (b) a pool cue, (c) a basketball court, (d) an elephant, (e) a city block.

Expert Solution

(a)

To determine

The order of magnitude of the length of the mouse

The order of magnitude of the length of the mouse is 101m

### Explanation of Solution

Length is the measurement of distance between the two ends of an object. Its SI unit is meter.

Approximately, a mouse is of length between 4 cm to 15 cm. Thus, the order of magnitude of the length of the mouse is

lm=4cm (1m102cm)to 15cm(1m102cm)=0.04m to 0.15 m=101m

Expert Solution

(b)

To determine

The order of magnitude of the length of the pool cue

The order of magnitude of the length of the pool cue is 100m

### Explanation of Solution

Approximately, a pool cue is of length equal to one meter. Thus, order of magnitude of the length of the pool cue is lpc=1m=100m

Expert Solution

(c)

To determine

The order of magnitude of the length of the basket ball court

The order of magnitude of the length of the basket ball court is 101m

### Explanation of Solution

Estimated length of the basketball court is equal to 28 m. Thus, the order of magnitude of the length of the basket ball court is lbc=28m=101m

Expert Solution

(d)

To determine

The order of magnitude of the length of an elephant

The order of magnitude of the length of an elephant is 101m

### Explanation of Solution

Approximately, the length of an elephant is 8 m. Hence, the order of magnitude of the length of an elephant is le=8m=101m

Expert Solution

(e)

To determine

The order of magnitude of the length of city block

The order of magnitude of the length of city block is 102m

### Explanation of Solution

Approximately, a city block is of length equal to one hundred meter. Thus, the order of magnitude of the length of the length of the city block is lcb=100m=102m
