your answer wil2. A farmer moves along theboundary of a square field of side10 m in 40 s. What will be themagnitude of displacement of thefarmer at the end of 2 minutes 20seconds from his initial position?9:45 anl10:00 am10:15 am10:30 am10:45 am11:00 amfor

Answer»

Total distance 40m in 40 sec.Total time taken by the farmer = 2 min 20 sec =140 sec Total rounds completed = 140/40 =3.5 rounds

That means if the farmer starts from point A of the square field, he reaches point C.

Therefore, displacement is AC.

Assume ABC is a right angled triangle. Therefore, AC^2= AB^2 + BC^2 AC^2 = (10)^2 +(10)^2 AC^2 = 100+100 AC^2 = 200 AC = (200)^1/2 AC = 10×(2)½

A Container contains 80 degree celsius hot water after every 10 minutes the change in temperature is _4 degree celsius after how much time will the temperature of water be 12 degree celsius

Answer»

Current Temperature = 80Final Temperature = 12

Total Change in temperature = 80 - 12 = 68 degree celsius

Every 10 minutes , 4 degree celsius drop is observed

We get , 68 / 4 = 17

Hence, there will be 4 degree celsius drop 17 times

That is, 17 x 10 = 170 minutes

is the given change -4 degree?then answer is 170 mins or 2 hr 50 mins

let after x min temp is 12.then 80-(4x/10)=12

solve it to get the answer.

Answer»

given area pi r^2 = 754600 m^2==> r^2 = 754600 * 7/22 = 68600 * 7/2 = 34300 * 7 = 7^2 * 7^2 *10^2So r = 490 mCircumference of that circular track = 2 pi r = 2 * 22/7 * 490 = 22 * 140 mSo for 20 rounds the distance covered = 20 * 22 * 140mTime taken to go for 20 rounds = distance / speedt = 20 * 22 * 140 / (16 * 5/18) [here km p h is changed into m/s]So time taken = 200 * 22 * 14 * 18 / 80 = 13860 sOr 13860/60 min= 231 min =3 hour 51 minute
