Question

1.Find the power of an engine, which can do a work of 12000 joules in 8 seconds.

Answer 1

Answer:

x = 12000/8

x = 1500/1

the power of engine of one second is 1500 joules

Answer 2

☀️ Given that, an engine can do a work of 12,000 joules in 8 seconds and we need to find the power of that engine.

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━

❍ To calculate the power of engine we must know that ::

P = W/t

Where,

• P denotes power
• W denotes work done
• t denotes time taken

Finding Power of engine :-

⤳  P = 12000/8

⤳  P = 6000/4

⤳  P = 3000/2

⤳  P = 1500 Watts

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━

H E N C E,

• The power of engine is 1500 Watts
