Skylar travels 50 meters N and then goes 30 meters W before coming straight back south 20 meters. What distance did she travel?
lesya [120]

Answer:

100\ \text{meters}.

Explanation:

Distance Skylar traveled North is 50\ \text{meters}

Then she traveled 30\ \text{meters} Westward.

After which she traveled 20\ \text{meters} towards the South.

The total distance traveled would be the sum of the distances.

50+30+20=100\ \text{meters}

The distance traveled by Skylar was is 100\ \text{meters}.

How are gravity and electromagnetic force similar and different?
oksano4ka [1.4K]

Answer:

The biggest difference is that gravity is an attractive force while electromagnetism is both an attractive and repelling force. Gravity happens between two objects depending on their masses, while electromagnetism is dependent on the objects' electric charges and the distance between them.

Explain why, under some circumstances, it is not advisable to weld a structure that is fabricated with a 3003 aluminum alloy. Hi
Scorpion4ik [409]

The 3003 aluminum alloy is made up of 1.25% Magnesium and 0.1% Copper. This combination is designed to increase the strength of the material over other types of alloys such as those of the 1000 series. This alloy provides a medium strength and can be educated by cold work.

The alloy is not heat treatable and generally has good formability, corrosion resistance and weldability.

However, being a material that hardens by cold work, welding a 3003 Aluminum structure will cause the body to undergo recrystallization which will generate a loss in the 'resistance' of the material and the force capable of withstanding. If this aluminum will be used for structural purposes, it should not be welded. It would be better to perform the structure with a 6061 aluminum, which has similar characteristics and is not so affected by welding.
