Question

A Tractor 900Joules of work in 5 minutes what will be the power of Tractor​

Answer 1

★ Given That :

• ➻ Work Done by Tractor (W) = 900 J
• ➻ Time Taken by Tractor (T) = 5 min

★ Need To Find :

• ↠ Power of the Tractor?

⌬ Formula Used Here :

• ➟ ✪ Power = Work done / Time ✪
• ➟ ✪ P = W / t ✪

_____________________

⚘ Conversion Needed :

• ➣ 5 Minutes into seconds :
• ➣ [ 1 min = 60 second ]
• ➣ 5 × 60 second
• ➣ Time taken = 300 seconds

✇ Putting Value in Formula :

• ⇒ Power = Work done / Time
• ⇒ Power = 900 / 300
• ⇒ Power = 9 / 3
• ⇒ Power = 3 Watts

✧ Hence :

• ➮ The Power of Machine is 3watts .

Answer 2

★ Information provided with us:

• A Tractor 900 Joules of work in 5 minutes

★ What we have to calculate:

• Power of the tractor.

★ Required formulas to solve this question:

• $\red \bigstar \: \underline{\boxed{\sf{P \: = \: \dfrac{W}{T} }}} \: \red \bigstar$

Where,

• P is power
• W is work done
• T is time taken

★ Changing minutes into seconds:

• We know that 1 minute contains 60 seconds. So 5 minutes would contain,

$: \leadsto \: 1 \sf{\: minute \: = \: 60 \: seconds}$

$: \leadsto \: 5 \sf{\: minutes\: = \: 60 \: \times 5s}$

$: \leadsto \: \boxed{5 \sf{\: minutes\: = \: 300s}}$

★ Substituting the values in the formula:

We have,

• W is 900J
• T is 300s

Power is the rate of doing a specific work.

Power is measured in watts.

Now,

$: \longmapsto \: \sf{P \: = \: \dfrac{900}{300} }$

• Cancelling the zeroes,

$: \longmapsto \: \sf{P \: = \: \dfrac{9 \cancel{00}}{3 \cancel{00}} }$

$: \longmapsto \: \sf{P \: = \: \dfrac{9}{3}}$

• Dividing by 3,

$: \longmapsto \: \sf{P \: = \: \cancel\dfrac{9}{3}}$

$: \longmapsto \: \pink \bigstar\underline{\red{\boxed{\sf{P \: = \: 3}}}} \pink \bigstar$

• Power of the tractor would be of 3 watts
