A large box sits on a rough floor. A person pushes on the box with a horizontal force of magnitude 50 N. The box remains at rest
artcher [175]

Answer:

The magnitude of the frictional force is   F_f \ge 50 \ N

Explanation:

From the question we are told that

   The force exerted on the box is  F =  50 \  N

Generally for the box to remain at rest then it means that the frictional  force is greater than or equal to the force applied to move it i.e

         F_f \ge F

=>      F_f \ge 50 \ N

When a man returns to his well-sealed house on a summer day, he finds that the house is at 35°C. He turns on the air conditioner
Paul [167]

Answer:

1353.38 Watt

Explanation:

T₁ = Initial temperature of the house = 35°C

T₂ = Final temperature of the house = 20°C

Δt = Time taken to cool the house = 38 min = 38×60 = 2280 s

m = mass of air in the house = 800 kg

Cv = Specific heat at constant volume = 0.72 kJ/kgK

Cp = Specific heat at constant pressure = 1.0 kJ/kgK

Heat removed

q = mCvΔT

⇒q = 800×720×(35-20)

⇒q = 8640000 J

Average rate of hear removal

Q=\frac{q}{\Delta t}\\\Rightarrow Q=\frac{8640000}{2280}\\\Rightarrow Q=3789.47\ W

COP=\frac{Q}{W}\\\Rightarrow W=\frac{Q}{COP}\\\Rightarrow W=\frac{3789.47}{2.8}\\\Rightarrow W=1353.38\ W

∴ Power drawn by the air conditioner is 1353.38 Watt
