Particle distance refers to the minimal distance between two particles within a system. It is an important factor in determining the overall structure and behavior of the particles within a material or substance. The distance between particles can influence properties like density, strength, and conductivity.

What is the formula of mean particle size?
The formula for mean particle size is calculated by summing the individual particle sizes and dividing by the total number of particles. Mathematically, it is expressed as mean particle size = (Σ particle sizes) / total number of particles.
What is the force of repulsion between an alpha particle and a gold nucleus when the alpha particle passes by the nucleus at a distance of 1pm?
The force of repulsion between the alpha particle and the gold nucleus can be calculated using Coulomb's law, given by F = k * (q1 * q2) / r^2, where k is the Coulomb constant, q1 and q2 are the charges of the particles, and r is the distance between them. Given the charges of an alpha particle and a gold nucleus, and the distance of 1pm, the force of repulsion can be calculated to be extremely large due to the proximity of the particles and the high charges involved.
What is distance - time graph?
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.)
What is its SI unit of angular velocity?
Particle displacement is a measurement of distance of the movement of a particle in a medium as it transmits a wave. Distance is measured in meters.
What does dust mean?

The strength of the electric field of a charged particle becomes greater as the distance from the particle increases.?
No, the strength of the electric field of a charged particle becomes weaker as the distance from the particle increases. The electric field strength follows an inverse square law relationship with distance, meaning it decreases as the distance from the charged particle increases.
What is the mean square displacement formula used to calculate in the context of particle movement?
The mean square displacement formula is used to calculate the average distance a particle moves from its starting point over a period of time. It is calculated by squaring the distance traveled by the particle at each time step, summing these values, and then dividing by the total number of time steps.
What is the process for conducting a mean square displacement calculation?
To conduct a mean square displacement calculation, you first need to track the position of a particle over time. Then, calculate the squared distance the particle has moved from its starting point at each time interval. Finally, average these squared distances to find the mean square displacement, which represents the average distance the particle has traveled from its starting point over time.
When does distance travelled by a particle is proportional to time?
The distance travelled by a particle is proportional to time when the particle moves with a constant velocity. This means that for every unit of time that passes, the particle covers a consistent amount of distance.
When the distance from a charged particle decreases the strength of the electric field does what?
As the distance from a charged particle increases the strength of its electric field DECREASES.
Can the distance travelled by a particle be zero when displacement is not zero?
The distance travelled by a particle cannot be zero when displacement is not zero because unlike distance which is a scalar, displacement is a vector quantity implying that it has both direction and magnitude.
Time of travel of particle in terms of speed of particle?
If the distance of travel remains constant in every case, then the time required to cover the distance is inversely proportional to the speed of the particle. T = (constant) divided by (speed) or: (Time) x (Speed) = A constant, if the distance under consideration doesn't change. Note: This expression is a good approximation at everyday speeds. It becomes less accurate at speeds where relativistic effects become significant.
What is the formula of mean particle size?
The formula for mean particle size is calculated by summing the individual particle sizes and dividing by the total number of particles. Mathematically, it is expressed as mean particle size = (Σ particle sizes) / total number of particles.
If the displacement of particle is zero then the distance travelled by it will be?
Negative
Can the distance travelled by the particle be zero when the displacement is not zero?
The distance travelled by a particle cannot be zero when displacement is not zero because unlike distance which is a scalar, displacement is a vector quantity implying that it has both direction and magnitude.
The strength of the electric field of a charged particle becomes greater as the distance from the particle decreases?
Yes, the strength of the electric field of a charged particle does increase as you move closer to the charged particle. This is because electric fields follow an inverse square law, meaning that the field strength is inversely proportional to the square of the distance from the charged particle. As you move closer, the distance decreases, leading to an increase in the electric field strength.
What is the distance traversed by the particle between 0 seconds and 6 seconds?
The distance, expressed in inches, is(1.2) x (the particle's average speed, in feet per minute) .
