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.

Voltage = Current x Resistance 
<span>Voltage(?) = 100 x 1.98x10^-4 ohms </span>

<span>Voltage = Current x Resistance </span>

Sawyer launches his 180 kg raft on the Mississippi River by pushing on it with a force of 75N. How long must Sawyer push on the
Daniel [21]

Answer: 4.8 s

Explanation:

We have the following data:

m=180 kg the mass of the raft

F=75 N the force applied by Sawyer

V=2 m/s the raft's final speed

V_{o}=0 m/s the raft's initial speed (assuming it starts from rest)

We have to find the time t

Well, according to Newton's second law of motion we have:

F=m.a (1)

Where a is the acceleration, which can be expressed as:

a=\frac{\Delta V}{\Delta t}=\frac{V-V_{o}}{t-t_{o}} (2)

Substituting (2) in (1):

F=m\frac{V-V_{o}}{t-t_{o}} (3)

Where t_{o}=0

Isolating t from (3):

t=\frac{m(V-V_{o})}{F} (4)

t=\frac{180 kg(2 m/s-0 m/s)}{75 N}

Finally:

t=4.8 s
