Two objects with a mass of 2 kg and 4 kg, respectively, are moving at a speed of 20 m / s. The momentum of each of these objects is ...

help answer the task soon

40kgm/s and 80kgm/s

Explanation:

Momentum is the amount of motion a body possesses. It is mathematically expressed as;

  Momentum  = mass x velocity

For the first body,

 Mass  = 2kg

 velocity  = 20m/s

Momentum  = 2 x 20  = 40kgm/s

For the second body;

   Mass  = 4kg

    velocity  = 20m/s

    Momentum  = 4 x 20  = 80kgm/s

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

girl imma just put my comment here because i need a couple point okurrttt
