Answer:


Explanation:
Given:
- mass of the object,

- elastic constant of the connected spring,

- coefficient of static friction between the object and the surface,

(a)
Let x be the maximum distance of stretch without moving the mass.
<em>The spring can be stretched up to the limiting frictional force 'f' till the body is stationary.</em>


where:
N = m.g = the normal reaction force acting on the body under steady state.


(b)
Now, according to the question:
- Amplitude of oscillation,

- coefficient of kinetic friction between the object and the surface,

Let d be the total distance the object travels before stopping.
<em>Now, the energy stored in the spring due to vibration of amplitude:</em>

<u><em>This energy will be equal to the work done by the kinetic friction to stop it.</em></u>




<em>is the total distance does it travel before stopping.</em>

Answer:
E=6.91 N/C
Explanation:
Given that
Linear Charge density ,λ = 5 nC/m
Distance ,R= 13 m
We know that formula for long wire to find electric field

E=Electric field
R=Distance
εo=8.85 x 10⁻¹² C²/N.m²
λ=Linear Charge density
Now by putting the values

E=6.91 N/C
Therefore the electric filed at distance 13 m will be 6.91 N/C
Answer:
The percentage of the population that is actively participating in the labor market, whether working or looking for a job, is 95% of the total working age population.
Explanation:
If the number of unemployed in a country is 19 million people, and that number represents an unemployment rate of 4%, to know the total number of economically active people in the country we must perform the following calculation:
(19,000,000 / 4) x 100 = X
475,000,000 = economically active population
However, the country has a working-age population of 500 million people, of which only 475 are actively participating in the labor market. To know the percentage that these 475 million people represent, we must perform the following cross multiplication:
500 = 100
475 = X
(475 x 100) / 500 = X
95 = X
The percentage of the population that is actively participating in the labor market, whether working or looking for a job, is 95% of the total working age population.
