Why does a empty bottle colapse when kept in a fridge explain in detail |
|
Answer» When kept INSIDE the REFRIGERATOR, the water vapors inside the bottle will condense, leaving a lot of empty space inside the bottle. The air outside the bottle will exert extra PRESSURE which would lead to the bottle COLLAPSING. |

Evaporation causes cooling in the environment as |
|
Answer» Heat and EvaporationWhen a liquid evaporates, its molecules convert from the liquid PHASE to the vapor phase and escape from the surface. Heat drives this process. In order for the MOLECULE to LEAVE the liquid surface and escape as a vapor, it must take heat energy with it. The heat that it takes with it comes from the surface from which it evaporated. Since the molecule is taking heat with it as it’s LEAVING, this has a cooling effect on the surface left behind. This makes it easy to understand evaporative cooling |

All solids expand by different amount when heated through the same temperature increase. Explain with the help of an example. |
| Answer» TION:any integer n greater than or equal to 0.The FACTORIAL is the product of all integers LESS than or equal to n but greater than or equal to 1. The factorial VALUE of 0 is by definition equal to 1. For negative integers, factorials are not defined. The factorial can be seen as the result of MULTIPLYING a sequence of descending natural numbers (such as 3 × 2 × 1). | |

Find the average speed of an objects it covers 25cm in 5 minutes |
|
Answer» o find the average speed for the car to cover the distance of 5 km, we will divide the value of the distance by that of the TIME travelled, now to find the velocity in TERMS of km/hr, we NEED to convert the time from minute to hour by dividing it by 60 and the formula for the speed is:Speed = DistanceTimeComplete step by step answer:The distance travelled by the car in km is GIVEN as 5 km.The time taken to cover the distance of 5 kmis 5 min.Now to convert the time from minute to hour is given by dividing the minute value by 60. Hence, the minute value is:⇒560=112hNow using the time, distance and speed formula, we find the value of the speed in terms of km/hr as:Speed = DistanceTimePlacing the value of distance and time in the above formula, we get the value of the speed as:⇒Speed = 5 km112hr∴Speed = 60 km/hrTherefore, the value of the speed of the car moving a distance of 5 km is given as 60 km/hr.Note:Another method to find the speed is by CONVERTING the distance from 5km to 5000m and time from minute to seconds as 5min to 5×60=300 seconds, then using the formula of the speed and its value as:Speed = DistanceTimePlacing the value of distance and time as 5000m and 5min respectively. The value of the speed in terms of m/sec is:Speed = 5000300⇒Speed = 5000300 m/sNow to find the speed in terms of km/h from m/s, we will multiply the speed by 185 to get the speed in terms of km/h unit.⇒Speed = 5000300×185⇒Speed = 60 km/hr===============================Answer By shreyash |

a train is travelling at a speed of 60km/HR. Brake are applied so as to produce a uniform acceleration of-0.5m/s^2. find how for the train will go before it is bought to rest |
| Answer» VELOCITY, u = 60 km/h= 60×1000/3600 m/s¹= 60000/3600 m/s¹= 600/36 m/s¹= 16.67 m/sFinal velocity, v = 0 m/sAcceleration, a = - 0.5 m/s²Distance travelled =?Using, = v² = v² - u²/2aS = v² - u²/ 2a= 0² - 16.67²/2(-05)= 227.889 m/s².Therefore, TRAIN will GO 277.889 m before it BROUGHT to rest.please mark me brain mark list | |
