Answer:
the equilibrium wage rate is 10 and the equilibrium quantity of labor is 1000 workers
Explanation:
The equilibrium wage rate and the equilibrium quantity of labor are found as the point where the equation of demand intercepts the equation of supply, so the equilibrium quantity of labor is:
15 - (1/200) L = 5 + (1/200) L
15 - 5 = (1/200) L + (1/200) L
10 = (2/200) L
(10*200)/2 = L
1000 = L
Then, the equilibrium wage rate is calculated using either the equation of demand for labor or the equation of supply of labor. If we use the equation of demand for labor, we get:
W = 15 - (1/200) L
W = 15 - (1/200) 1000
W = 10
Finally, the equilibrium wage rate is 10 and the equilibrium quantity of labor is 1000 workers
Answer:
a. I = 30 A
b. E = 1080000 J = 1080 KJ
c. ΔT = 12.86°C
d. Cost = $ 4.32
Explanation:
a.
The current in the coil is given by Ohm's Law:
where,
I = current = ?
V = Voltage = 120 V
R = Resistance = 4 Ω
Therefore,
<u>I = 30 A</u>
<u></u>
b.
The energy can be calculated as:
<u>E = 1080000 J = 1080 KJ</u>
<u></u>
c.
For the increase in the temperature of water:
where,
m = mass of water = 20 kg
C = specific heat of water = 4.2 KJ/kg.°C
Therefore,
<u>ΔT = 12.86°C</u>
<u></u>
d.
First, we will calculate the total energy consumed:
Now, for the cost:
<u>Cost = $ 4.32</u>
