What is fractional ditilation |
|
Answer» It is used for separation of two miscible liquids when difference in their boiling point is less than 25°C Palak you had done a mistake the temperature is 25°C but you had written 25K. When the difference between the boiling point of two miscible liquid is less than 25°C then the process of fraction disstilation is applied. ??? Fractional distillation is a process of separating 2 micible liquids which have their differences in their boiling point more than 25K |

Newton 1 law |
|
Answer» Acc. to Newton first law of motion a body in rest want to be in rest, a body in motion want to be in motion,unless until any external force applied on it. If an object is in motion will remain in uniform motion and if a object is in rest will remain in rest unless until acted upon by an unbalanced force If an object is in rest it will remain in rest and if the object is in motion it will remain in motion until and unless an external force is applied on it. Every object in rest want to remain in rest and object in motion want to remain in motion till an external force exerted on it. |

Estimate the mass of an object with weight 49Newton? |
|
Answer» W=m×g. So; m=w÷gThen, 49÷9.8 =5kg. answer. We know that,Weight = mass×acceleration due to gravity.Let weight=wLet mass=mLet acceleration due to gravity=gW=m×gSo,m=w÷gW=49G=9.8m/s^2M=5kgHence mass is 5 kilograms. 4900grams and convert it into kg |

If the moon attracts the earth why does earth does not move around the moon |
|
Answer» Because the mass of earth is more than the mass of moon, we know that mass is directly propotional to gravitational force, so the earth having more gravitatinal force due to moon does not attracts the earth Earth have more gravitational force rather than moon Because Acceleration produced in earth is negligible due to its more massAs acceleration is indirectly proportional to mass.. Because earth gravitational force is more |

Difference between Gravity nd Gravitation. |
| Answer» Difference Between Gravitation and GravityThe term Gravitation is said to be the force that is acting between two bodies. On the other hand, gravity is the force that is occurring between an object and the earth surface.The force of Gravitation is also said to be representing a force that is directly proportional to the product of the masses of two objects and is inversely proportional to the square of the distance between them. Usually, gravity is being considered as the natural property due to which the objects are said to be attracted towards earth. It is said that gravity plays a major role in sustaining life on earth. This is due to the fact that the term gravitational pull acts between the earth, the sun and the atmosphere is kept on our planet earth. Hence, it is the reason behind the air that we need to breathe for our survival. Not only this, but it also helps us to be at a safe distance from the star and sun.In our universe, each and every object attracts the other with a certain amount of force. The large distance of separation is one of the main reasons for the weak nature of the force of attraction.\t\tThe gases in the sun are held together due to the force of gravity.\t\t\tGravity is also a responsible force for water to rest at the bottom of a glass and hovering over at the top of the glass.\t\t\tThe force of attraction acting between the earth surface and the moon causes tides in the ocean. This is also the result of gravity.\t\t\tThe force of Gravity causes the moon to revolve around the earth.\tGravity has the same effect on every object. If we drop an iron rod and a feather, they both will fall at the same speed. Due to the external effect like air resistance on gravity, it might seem that the iron rod falls at a greater speed. But, if we drop them in a vacuum, they would fall at the same time. The Gravity of an object is directly proportional to the mass of that object. It is one of the weakest known forces in nature. | |
