jek_recluse [69]

Answer:

A(n)  <u>living wage</u> is the idea that people should be able to purchase the essentials of life by working a forty-hour workweek. Many local municipalities have as a result set higher minimum wages than the federally mandated minimum wage to accomplish this goal.

Explanation:

Living wage is the idea given to reduce poverty specially in cities with higher costs. It's based on the fact that one who works forty hours per week, he or she should be able to afford the basic needs of life that includes the water, food and shelter. Research has shown that the implementation of this concept has played the role in reducing poverty and enhancing the quality of life of workers. Countries like New-Zealand and united kingdom has supported this concept.

Write three nuclear equations to represent the nuclear decay sequence that begins with the alpha decay of u-235 followed by a be
vazorg [7]

Answer:

We know that in the decay process the sum of molecular number as well as molecular weight should be constant.

The following three reaction are as follows

1 .

Alpha decay  of parent nuclide

_{92}^{235}\textrm{U} \rightarrow _{90}^{231}\textrm{Th}+_{2}^{4}\textrm{alpha }

The molecular number of alpha particle is 2 and molecular weight is 4 g/mol.

2.

Beta decay of daughter nuclide

_{90}^{231}\textrm{Th}\rightarrow _{91}^{231}\textrm{Pa}+_{-1}^{0}\textrm{beta}+v

v is the neutrino emission,The charge on the beta particle is zero.

3.

Alpha decay

_{91}^{231}\textrm{Pa}\rightarrow_{89}^{227}\textrm{Pa}+_{2}^{4}\textrm{alpha}

A copper wire has a length of 1.50 m and a cross sectional area of 0.380 mm2. If the resistivity of copper is 1.70 ✕ 10−8 Ω · m
sweet [91]

Answer: 1.044 E -17 A

Explanation:

L =1.50m

A = 0.380mm = 3.8E- 7

Resistivity p =1.70 E-8

R =pl/A

R = 1.70 E-8 × 1.5/ 3.8 E-7

R = 6.71 E-16 ohms

V = IR

0.700 = I × 6.71 E-16

I =1.044E-17 A
