Answer:
The electric bill for June is Rs198000
Explanation:
Convert volt to watt, but in order to do so I need to know the amps and since it is not provided I converted if the amps was 1.
I multiple 50 with 10 then with 30 so I know how much watt the fan takes at June.
Since there are 2 light bulb I multiple 10 with 2 than with 8 than with 30.
15000 watts for the fan,
4800 watts for light bulb,
add them and then times it by 10.
Rs198000
They both flow in currents. Water has a pump that works like a battery and pipes that work like a circuit.

The total amount of energy per hour is 
Explanation:
In this problem we are told that the amount of energy reaching a square meter in the United States per hour is
The total surface area of the United States is
And converting into squared metres,
Therefore, the total energy reaching the entire United States per hour is given by:

Answer:
a) α = 0.338 rad / s² b) θ = 21.9 rev
Explanation:
a) To solve this exercise we will use Newton's second law for rotational movement, that is, torque
τ = I α
fr r = I α
Now we write the translational Newton equation in the radial direction
N- F = 0
N = F
The friction force equation is
fr = μ N
fr = μ F
The moment of inertia of a saying is
I = ½ m r²
Let's replace in the torque equation
(μ F) r = (½ m r²) α
α = 2 μ F / (m r)
α = 2 0.2 24 / (86 0.33)
α = 0.338 rad / s²
b) let's use the relationship of rotational kinematics
w² = w₀² - 2 α θ
0 = w₀² - 2 α θ
θ = w₀² / 2 α
Let's reduce the angular velocity
w₀ = 92 rpm (2π rad / 1 rev) (1 min / 60s) = 9.634 rad / s
θ = 9.634 2 / (2 0.338)
θ = 137.3 rad
Let's reduce radians to revolutions
θ = 137.3 rad (1 rev / 2π rad)
θ = 21.9 rev
