Answer

No.14 carries more current than No.18

Explanation

In the American Wire Gauge(AWG) current ratings, the higher the number the thinner the wire.A typical household wire is AWG number 12 or 14. Telephone wire is typically AWG 22, 24 or 26.The higher the gauge number, the smaller the diameter and the thinner the wire. Due to less electrical resistance, a thicker wire carries more current with less voltage drop as compared to a thinner wire. It is advisable that for longer distances, it will be necessary to increase the wire diameter and reduce the gauge so as to limit the voltage drop.

Clint wants to keep a young tree from blow- ing over during a high wind. He decides that he should tie a rope around the tree at

Sergio039 [100]

Answer:

No, the 270 cm rope Clint has is not enough to do the job.

Explanation:

The height of tree where rope has to be tied = 180 cm

The distance of the stake from the base of the tree = 200 cm

We can say that the arrangement makes a right angle triangle, with the right angle situated at the base of the tree. The figure is attached below. Consult it for better understanding.

Length of the rope can be found by using Pythagoras theorem.

(Length of rope)² = 180² + 200²

Length of rope = 269 cm

As it is stated the additional 30cm of rope is required for tying from both ends. Total length of rope required is:

Total length of rope = 269 + 30

Total length of rope = 299 cm

As length of rope required is 299cm, the 270 cm rope Clint has is not enough to do the job.
