Answer:

paying bills online instead of sending paper through the mail

Explanation:

In today's era everyone is aware about the Climate change and wants to contribute towards environment protection. A simple technique is to follow four R's which are: Reduce, Reuse, Recycle and Refuse. The four examples given over here are examples of each R as explained below:

Reduce:  paying bills online instead of sending paper through the mail as we are reducing the paper use over here.

Reuse: donating gently used clothes and household items so that they can be reused. Using plastic bags a second time to avoid buying new ones.

Recycle & Refuse: buying products that can be recycled so they don’t end up in the trash

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.

ladessa [460]

Answer:

a = 3 m/s²

Explanation:

a = Δv/t

a = (vf - vi)/t

a = (9 - 0)/3

a = 3m/s²

2) A tomato is launched upwards with a velocity of 27 m/s. What is its height after 2.1 seconds in the air?
olga_2 [115]

The height of the tomato in air after 2.1 seconds is 78.31 m.

<h3 /><h3>What is height?</h3>

Height can be defined as vertical distance either between the top and bottom of something or between a base and something above it.

To calculate the height of the tomato after 2.1 seconds, we use the formula below.

Formula:

  • H = ut+gt²/2............. Equation 1

Where:

  • H = Height of the tomato
  • u = Initial velocity = 27 m/s
  • g = Acceleration due to gravity = Constant = 9.8 m/s²
  • t = 2.1 seconds

Substitute these values into equation 1

  • H = (27×2.1)+(9.8×2.1²)/2
  • H = 56.7+21.609
  • H = 78.31 m

Hence, the height of the tomato after 2.1 seconds is 78.31 m.
