Answer:
8.97 Watt
Explanation:
Resistance, R = 20 ohm 
Inductance, L = 10 mH 
V(t) = 20 Cos (1000 t + 45°)
Compare with the standard equation 
V(t) = Vo Cos(ωt + Ф) 
Ф = 45°
ω = 1000 rad/s 
Vo = 20 V 
Inductive reactance, XL = ωL = 1000 x 0.01 = 10 ohm 
impedance is Z. 


Z = 22.36 ohm 



Apparent power is given by 
P = Vrms x Irms 
P = 14.144 x 0.634 
P = 8.97 Watt

Answer:
The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state.
 
        
                    
             
        
        
        
Answer:
35%
Explanation:
The car's engine gives off 65% thermal energy 
So only 35 % is converted into mechanical energy .
input heat = Q₁ = 100 
output heat = Q₂ = 65 
Work output = Q₁ - Q₂ = W 
W = 100 - 65 = 35 
Efficiency = W / Q₁ X 100
= (35/ 100) X 100
= 35%.
