Question

how much work can a 2 horsepower Motor 2 in 1 hour?



plz plz urgent ​

Answer 1

Answer:

Explanation:

1Hp= 746 w

Then,

2Hp= 1492w

1 hour= 3600 sec

Work= power× time

1492×3600= 5371200j=5.3712× 10^6 j

Answer 2

Work done by the motor is  5.3 × $10^{6}$ J

Explanation:

Given:

Horsepower motor : 2HP

Time : 1 Hour

To find: Work done by the motor

Solution:

Power of motor, p = 2HP

where,

1 HP = 746 W

2 HP = 1492 W

Power of motor (p) = 1492 W

Time taken, t = 1 hr

1 Hr = 3600 s

We know that,

Power = W / time

Where,

W refers to work done

t is the time taken

Work done = P × t

Work done = 1492 × 3600

= 5.3 × $10^{6}$ J

Hence, Work done by the motor is  5.3 × $10^{6}$ J
