5. 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?
Momentum = (mass) x (velocity)If the particle is at rest, velocity = 0, and momentum = 0.
The charge/mass ratio for an alpha particle is 4.82245111 x 107 C/kg.Charge of alpha particle = 2e = 2 x 1.602176487×10−19 C = 3.20435297 ×10−19 CMass of alpha particle = 6.64465620×10−27 kg
Why the partical is not moving toward negative x-direction?
This question is ill-formed. You do not specify which particle you mean, nor what you mean by negative x-direction. Note that coordinate systems in physics are relative; they have no affect on physics, and can thus be chosen in any convient way. I could define your negative x-direction to be the positive x-direction if I wished to do so.

x = 4 - 6 t2Speed = (dx/dt) = - 12 tSpeed = 0 when t = 0x(0) = 4The particle stops at [ t = 0 ], located at [ x = 4 ].The physical reality is: The particle started at [ x = 4 ], and once it started moving, it never stopped.
Momentum = (mass) x (velocity)If the particle is at rest, velocity = 0, and momentum = 0.

Yes
Though both are forms of ionizing radiation, an X-ray is a form of electromagnetic radiation, while a beta ray is actually a beta particle. The beta particle is a form of particulate radiation, and the beta particle could be either an electron or a positron.
A graph that shows displacement plotted against time for a particle moving in a straight line. Let x(t) be the displacement of the particle at time t. The distance-time graph is the graph y=x(t), where the t-axis is horizontal and the y-axis is vertical with the positive direction upwards. The gradient at any point is equal to the velocity of the particle at that time. (Here a common convention has been followed, in which the unit vector i in the positive direction along the line has been suppressed. The displacement of the particle is in fact a vector quantity equal to x(t)i, and the velocity of the particle is a vector quantity equal to x(t)i.)
i did work on particles I didnt learn a thing x sorry !
No, a proton is a positively-charged particle with a mass of 1.673 x 10-27 kg. What you described is a neutron.
kinetic energy is the energy that a particle has obtained due to its motion.It mainly depends upon the mass of the body and its velocity. kinetic energy is mathematically calculated as (0.5 x mass of the body x square of its velocity)
