In simple terms a force is what makes anything do move or stay still. Some forces are contact forces and some are non contact. Hope this helps.

Answer:

a force is any interaction that is unchallenged will change the motion of an object you might have heard of the push pull example

Explanation:

The equation to find force is

force = mass * acceleration or F = M * A

Force never creates motion!! although motion can occur

force is measured in the SI unit of newtons

a good example would be kicking a football when the foot ball is kicked your foot is interacting with the ball the ball is the object and your foot is the motion that is pushing on the ball which will then make the ball accelerate in the air so i think to find the force of the ball you take the mass of the object in this case the ball and multiply it by it acceleration or the change in its velocity to get force

idk i really hope this helps T^T

How much faster does helium escape through a porous container than ozone?
otez555 [7]
According to Graham's Law ," the rates of effusion or diffusion of two gases are inversely proportional to the square root of their molecular masses at given pressure and temperature".

                                r₁ / r₂  =  \sqrt{M2 / M1}   ---- (1)

r₁    =  Rate of effusion of He

r₂    =  Rate of Effusion of O₃

M₁  =  Molecular Mass of He  =  4 g/mol

M₂  =  Molecular Mass of O₃  =  48 g/mol

Putting values in eq. 1,

                                r₁ / r₂  =  \sqrt{48 / 4}

                                r₁ / r₂  =  \sqrt{12}

                                r₁ / r₂  =  3.46

Result:
          Therefore, Helium will effuse 3.46 times more faster than Ozone.

A sample of radioactive material starts with 80 grams. After 3 half-lives have passed, how much radioactive sample remains?
Elanso [62]

Answer:

After 3 half lives 10 g of radio active material left.

Explanation:

Given data:

Total amount of radio active material = 80 g

Amount left after 3 half lives = ?

Solution:

At time zero = 80 g

At first half life = 80 g/2 = 40 g

At 2nd half life = 40 g/2 = 20 g

At 3rd half life = 20 g/2 = 10 g

Thus, after 3 half lives 10 g of radio active material left.
