Answer:
Please find the answer in the explanation
Explanation:
Friction is a force that opposes motion. One or two of the advantages of friction are break and ability of an object to walk.
Writing yes it is useful because when your writing because friction helps you see what your writing
ii. Rubbing. Yes, it is useful.
friction make it possible for two object to rub each other
iii. Skiing. No. It is not useful because With presence of friction, skiing will not be possible.
iv. Rotating a wheel No. It is not useful because Friction will oppose the rotation of the wheel.
Answer:
Thus, if field were sampled at same distance, the field due to short wire is greater than field due to long wire.
Explanation:
The magnetic field, B of long straight wire can be obtained by applying ampere's law
I is here current, and r's the distance from the wire to the field of measurement.
The magnetic field is obviously directly proportional to the current wire. From this expression.
As the resistance of the long cable is proportional to the cable length, the short cable becomes less resilient than the long cable, so going through the short cable (where filled with the same material) is a bigger amount of currents. If the field is measured at the same time, the field is therefore larger than the long wire because of the short wire.
The following enumeration is the list of actions which are
considered to be illegal when operating your boat:
1
Operating
the boat in a harsh or inconsiderate manner
2
Operating
the boat in the absence of safety equipment
3
Actual
weight exceeds the carrying capacity of the boat
4
Not
prohibiting the riders to sit on gunwales,
transom, stern, sides, bow or decking over the bow sides when the boat is
underway, except when sufficient guards or railings are provided
5
Operating
the boat or giving permission to other people to operate the boat while drunk
or under illegal substances
6
Operating
the boat and the wash or wake endanger any property or person
7
Operating
the boat in an area designated for swimming
8
Operating
the boat beyond a slow, no wake
speed in locations marked as no wake zones
We can see that in this case, the rule # 6 is being trespassed.
Therefore under Minnesota Boating Laws, we have committed an Illegal Operating
Practice.
