Part a)
per day electricity power consumed when 100 W bulb is used for 8 hours

for one year consumption

now the cost will be given

now when other energy efficient light is used

for one year consumption

now the cost will be given

 
        
             
        
        
        
Answer:
= 925.92 N
≅ 926N
Explanation:
Pressure due to car = pressure due to applied force  
12000/18^2 = Force / 5^2
force = 12000 * 25/ 324 
= 925.92 N
For equilibrium
Pressure1 = Pressure2
A1F1 = A2F2
 12000*pi*(5^2) = F2 ( pi)*(18^2)
so, F2 = Applied force to lift car = 925.92 N
Pascal's principle
Pressure1 = Pressure2
F1/A1 = F2/A2 (F=force and A=area)
A1 =Pi*(0.05)²
A2 =Pi(0.18)²
F2=12000
F1 = 12000*(0.05)² / (0.18)² = 926N
