Question

solve the question home work !! ​

Answer 1

Gɪᴠᴇɴ :-

• Energy consumed (E) = 240 J
• Time taken (t) = 15 s

ᴛᴏ ғɪɴᴅ :-

• Power (P)

sᴏʟᴜᴛɪᴏɴ :-

We know that,

➭ Power = Energy consumed / Time taken

• ➭ P = E/t

• ➭ P = 240/15

• ➭ P = 16 W

Hence,

• Power (P) of machine is 16 W

Answer 2

$\huge \fbox \green{given}$

• $\sf work \: done \: by \: the \: machine = 240 \: j \:$
• $\sf \: time \: taken \: = \: 15 \: sec$

$\huge \fbox \green {To\:find}$

• $\sf power$

$\huge \fbox \green{Formula}$

$\underline{\boxed{\sf \: power \: = \: \frac{work \: done}{time}}}$

$\huge \fbox \green{Solution}$

$\sf \: power = \dfrac{240}{15} = 16$

$\sf \: hence \: the \: power \: of \: this \: machine \: is \: 16 \: watts$
