Explanation:

explanation is in above pic

Answer 2

$\huge {\orange {\bf {\underline {\underline {AnSwer}}}:-}}$

The Power of pump is 60 w.

━━━━━━━━━━━━━━━

Explaination :-

⟶ Gíven :-

• Mass, m = 720 kg
• Height, h = 15 m
• Time, t = 30 mins = 30 × 60 = 1800 secs
• Acceleration due to gravity, g = 10 m/s²

⟶ To fínd :-

the power of the pump

⟶ Solutíon :-

we know,

$\longrightarrow \bf Power = \frac{mgh}{t} \\ \\ \longrightarrow \sf P = \frac{720 \times 10 \times 15}{1800} \\ \\ \longrightarrow \sf P = \frac{108000}{18} \\ \\ \longrightarrow \boxed{ \bf P = 60w}$

Thus, the Power of pump is 60 w.
