4) terry's dog is racing down the lane in the part toward the east. the dog travels 36
meters in 18 seconds before it stops running. the velocity of the dog is.

a.2 m/s east
b.4 m/s east
c.8 m/s east
d.10 m/s east

A. 2 m/s

Explanation:

velocity = distance/time

velocity = 36 m / 18 s = 2 m/s

4) Terry's dog is racing down the lane in the part toward the east. The dog travels 36 meters in 18 seconds before it stops running.

36 meters in 18 seconds = 36/18 = 2 meters per second

The velocity of the dog is: 2 m/s

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
