This question involves the concepts of power and current.

The power output of the motor is "10.08 hp".

<h3>Power Output</h3>

The power output of the motor can be found using the following formula:

P = ηVI

where,

  • P = Power = ?
  • η = efficiency = 90 % = 0.9
  • I = current = 38 A
  • V = potential difference = 220 V

Therefore,

P = (0.9)(38 A)(220 V)

P = 7524 watt

converting this to horsepower:

P = (7524 watt)(\frac{1\ hp}{746\ watt})

P = 10.08 hp

olganol [36]

The equivalent of the resistance connected in the series will be Req=R₁+R₂+R₃.

<h3>
What is resistance?</h3>

Resistance is the obstruction offered whenever the current is flowing through the circuit.

So the equivalent resistance is when three resistances are connected in series. When the resistances are connected in series then the voltage is different and the current remain same in each resistance.

V eq    =    V₁    +    V₂    +    V₃

IReq    =    IR₁    +    IR₂   +    IR₃

Req    =    R₁    +    R₂   +    R₃

Therefore the equivalent of the resistance connected in the series will be Req=R₁+R₂+R₃.

Answer:

Answer for the question :

"the two boxcars A and B have a weight of 20 000 Ib and 30 000 Ib, respectively. If they coast freely down the incline when the brakes are applied to all the wheels of car A causing it to skid, determine the force in the coupling C between the two cars. The coefficient of kinetic friction between the wheels of A and the tracks is μk=0.5. The wheels of car B are free to roll. Neglect their mass in calculation."
