Question

the power of a motor which raising 200kg of water in 10 mins from a well of depth 60 m is​

Answer 1

Answer:

20joules

Explanation:

as power is the rate of work

here work is 200×60

12000

time is 600sec

so power is 12000/600=20joules

Answer 2

Aɴꜱᴡᴇʀ

$\huge{\pink{196 W}}$

Mass (m) = 200 kg

Depth of well = 60 m

Time (t) = 10m whic can also be written as 600 s

If we use the formula of power

$\begin{lgathered}\dashrightarrow {\tt{P \: = \: \dfrac{Work}{Time}}} \\ \\ \dashrightarrow \tt{P \: = \: \dfrac{mgh}{t}} \\ \\ \dashrightarrow \tt{P \: = \: \dfrac{200 \: \times \: 9.8 \: \times \: 60}{600}} \\ \\ \dashrightarrow \tt{P \: = \: \dfrac{12000 \: \times \: 9.8}{600}} \\ \\ \dashrightarrow \tt{P \: = \: 20 \: \times \: 9.8} \\ \\ \dashrightarrow \tt{P \: = \: 196} \\ \\ \large \boxed{ \leadsto \orange{{\sf{Power \: required \: by \: motor \: is \: 196 \: W}}}}\end{lgathered}$
