How is the conversion between N and mass kg?

How is the conversion between N and mass kg?


N is the force, kg, G is the mass, these are two completely different physical quantities, can not be converted by equal sign
Of course, kg and G can be converted, 1kg = 1000g
If gravity and other problems are involved, we can use G = mg to calculate, but n and kg can never be directly connected by an equal sign



Conversion between lbs and kg?


1Lbs=0.4532kg
2.2065lbs=1kg



How much kg is 100g?


I don't understand
100g=0.1kg



After water becomes ice, its volume increases by 10%. The volume of an existing ice is 44 cubic decimeters. How many cubic decimeters is the volume after melting into water?


If the volume of water is 1, the volume of water is 1 + 10% = 1.1
Therefore, the volume of water corresponding to 44 cubic decimeters of ice is 44 / 1.1 = 40 cubic decimeters
A: the volume of a piece of ice is 44 cubic decimeters, and the volume after melting into water is 40 cubic decimeters



China has started the "lunar landing project". It is assumed that on the surface of the moon, it takes t for the astronauts to measure the height h of a small object falling freely. When the Spacecraft flies in a circular orbit close to the surface of the moon, its orbit period is measured to be t, and the known gravitational constant is g. according to the above quantities, we try to find: (1) the acceleration of gravity on the surface of the moon; (2) the mass of the moon


Let the mass of the spacecraft be m, the mass of the moon be m, the radius of the moon be r, and the acceleration of gravity on the surface of the moon be g (1)



The volume of water increases by 1 / 11 when it forms ice. The volume of a piece of ice is 24 cubic decimeters. After the ice melts, what is the volume of water
Don't use equations


24 ÷ (1 + 1 / 11) = 22 cubic decimeters



China is carrying out the lunar landing project. If an astronaut takes a notebook to the moon, the quality of the notebook will be improved_____ , density_____ , gravity_____ .


The mass remains the same, the density remains the same, the gravity decreases (the gravity is 1 / 6 of the earth)



After water becomes ice, its volume increases by 1 / 10. The volume of the existing ice is 44 cubic decimeters, and that of the melted water is () cubic decimeters


V ice = V water * (1 + 0.1)
So V water = V ice / 1.1
So V water = 44 / 1.1 = 40
So, the volume after melting into water is (40) cubic decimeter



American astronaut Armstrong can't hear any sound after landing on the moon. What's the reason?


To be exact, there is no medium to transmit sound! Air is not the only medium! Water is OK! Solid is OK! And the moon has nothing!



After water becomes ice, its volume increases by 110. The volume of an existing ice is 2 cubic decimeters. What is the volume after melting?


2 (1 + 110) = 2 (1110) = 2011; & nbsp; a: the volume after melting is 2011
