What was the benefit of the government policies during the second industrial revolution?

Government policies during the second industrial revolution made it so that government couldn’t interfere with industrial growth. This type of system was called Laissez-faire. This economic system is sometimes called free market and was an idea that originated from Adam Smith in the 1700s.

a. E = 900000 J = 900 KJ

b. ΔT = 8.18 °C

c. Cost = $ 7.2  

Explanation:

a.

The energy can be given by:

where,

E = Energy = ?

P = Power = 500 W

t = time = (0.5 h)(3600 s/1 h) = 1800 s

Therefore,

E = 900000 J = 900 KJ

b.

The change in temperature of room air is given by the following formula:

  (since 50% of energy is used to heat air)

where,

m = mass of air = 50 kg

C = specific heat of air = 1.1 KJ/kg.°C

ΔT = Change in temperature of air = ?

Therefore,

ΔT = 8.18 °C

c.

First, we will calculate the total energy consumed:

Now, for the cost:

Cost = $ 7.2
