When an object fall from high.there should act only one type of force that is gravitation force of earth.except gravitation force of earth no other force should have applied on the object

Ganesh P 3 minutes ago

It is the object falling towards earth under the influence of attraction force of earth or gravity.

Gravity of the earth attracts every object towards its center. When an object is dropped from a certain height,it begins to fall towards earth's surface under the influence of gravitational force.such a motion of object is called free fall

Solution: Air is a mixture and not a compound because: Air does not have a formula like a mixture, while compounds have a fixed formula. When air is formed by gases, there is no energy change. Properties of air are variable and subjective to time and place.

Why do we have to use the s=ut+1/2 at^2 formula? The mathematically proven equations are as follows (1) First equation of Motion: V = u + at soln. Consider a body of mass “m” having initial velocity “u”.Let after time “t” its final velocity becomes “v” due to uniform acceleration “a”. Now we know that: Acceleration = change in velocity/Time taken => Acceleration = Final velocity-Initial velocity / time taken => a = v-u /t =>at = v-u or v = u + at This is the first equation of motion. (2) Second equation of motion: s = ut + 1/2 at^2 sol. Let the distance travelled by the body be “s”. We know that Distance = Average velocity X Time Also, Average velocity = (u+v)/2 .: Distance (t) = (u+v)/2 X t …….eq.(1) Again we know that: v = u + at substituting this value of “v” in eq.(2), we get s = (u+u+at)/2 x t =>s = (2u+at)/2 X t =>s = (2ut+at^2)/2 =>s = 2ut/2 + at^2/2 or s = ut +1/2 at^2 This is the 2nd equation of motion. Hope u got it.

For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. That is, the momentum lost by object 1 is equal to the momentum gained by object 2.

Yashi Choudhary 5 days, 21 hours ago

Conservation of momentum, general law of physics according to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total momentum of a system remains constant.

Let the mass of sodium sulphate required be 'x' g
The mass of water = 100 g
The mass of solution =(mass of sodium sulphate + mass of water) = (x + 100)g
Percentage of sodium sulphate in solution {tex}=\;\frac{Mass\;of\;sodium\;sulphate}{Mass\;of\;solution}\times100{/tex}
{tex}20=\frac{x}{x+100} \times 100{/tex}
20x + 2000 = 100x 
80x = 2000
x = {tex}\frac{2000}{80}{/tex}
= 25 g
Therefore,  the mass of sodium sulphate required is 25 g.
