Question

a pump raises water by spending 8×10^5 energy in 20 second. find the power of pump​

Answer 1

Explanation,

Given,

• Work done (W) = 8 × 10⁵ J
• Time taken (t) = 20 s

To Find,

• The power of pump.

Solution,

Applying power formula,

P = W/t

[ Put the values ]

↦ P = 8 × 10⁵ / 20

↦ P = 4 × 10⁴ watt

Therefore,

• The power of pump is 4 × 10⁴ watt.

For information about Power,

Definition :

• Power can be defined as the rate at which work is done i.e. energy converted.

Formula :

• The formula for power is , P = W/t.

Unit :

• MKS unit of power is watt (W).

• CGS unit of power is Erg/s .

• Work done (W) = 8 × 10^5 J
• Time (t) = 20 s

$\huge\color{purple}{\textbf{\textsf{TO FIND :-}}}$

• The power of the pump.

$\huge\color{purple}{\textbf{\textsf{SOLUTION :-}}}$

Applying power formula,

P = W/t

=> P = 8 × 10^5/20

=> P = 4 × 10⁴ W

Hence, the power of the pump is 4 × 10⁴ W.
