When faster moving and slower moving particles collide which particles gain energy?
It depends upon the mass of the particles also. Assuming equal mass, then the slower moving particle gains some energy, and the faster moving particle loses energy. However, if the slower moving particle had greater mass, it could transfer energy to the faster moving particle.
Which is the heaviest and slow moving particle in nuclear instrumentation?
The heaviestis the alpha particle.
What relation does the Brownian movement have to Thermometry?
In thermal equilibrium each degree of freedom of a physical system (like position x) has an expectation value for its energy of <E>=1/2 kB T, where kB is Boltzmann's constant and T is temperature. If you now measure the energy of the Brownian motion (e.g. <E>=1/2 k <x^2>, if it is a particle connected to a spring k with only degree of freedom x), you can calculate the temperature T=2<E>/k or T=k <x^2>/kB. In other words, the temperature can be determined from the Brownian motion x of the particle if the potential in which the particle is moving is well known. You could call this Brownian motion thermometry.
A particle is moving along the x-axis. The line graph shows the velocity of the particle over time. When is the instantaneous acceleration of the particle equal to 0?

What is an alfa particle?
An alpha particle is also considered a ray. It is a fast moving particle containing two protons and two neutrons.
What is a variant of the name of the line used to determine the acceleration of a particle moving along a curved surface?

What is the difference between air pressure and temperature?
Temperature is the average amount of energy that a (air) particle has. Pressure is the force that the moving particle exerts as it bumps into or pushes against a surface. The higher the temperature, the faster the particles will be moving and the more force they will exert when they bump into a surface. So as temperature goes up, so does pressure.
How do amoeba get food?
The amoeba moves its psuedopodia (false feet) around the food particle. thus a food vacuole is formed.then the amoeba secretes digestive enzymes into the food vacuole and the food particle is digested and assimilated.the waste particle is thrown out by moving the particle towards the surface of the body and it is excreted. :)

What can you infer about the friction between the atoms of a very fast flowing liquid?
The molecules inside have inadequate freedom and can only leave uncommonly or with great effort. As long as a liquid has some surface area exposed to the atmosphere, here and there a particle within the liquid near the surface will be moving fast sufficient. sry ifthis didnt help

What happens when an air particle pushes against another air particle?
The air particle with the greater force moves the other air particle in the general direction it was moving
Why is vacuum the best insulator?
In order for heat to be conducted, there have to be collisions between atoms or molecules, in which energy is transferred from a faster moving particle to a slower moving particle. In a vacuum there are no particles, hence, no particle collisions and no heat conduction.
