What else can I help you with?
Can the speed of the particle ever be negative if so give an example if not explian why?
see speed cannot de negative se speed = distance / time and neithr distance nor time can be negative they r always positive so speed cannot be negative but velocity can be negative
What can be said about the speed of a particle if the net work done on it is zero?
In that case, basically no force acts on the particle, and the particle moves at a constant speed. This constant speed may, or may not, be zero.
Is it possible in straight line motion particle have 0 speed and a non-zero velocity .explain?
Sounds like a trick question. The answer is no. Speed is a scalar with magnitude only and velocity is a vector with magnitude (speed) and direction. So If traveling with velocity in a straight line it has speed..
When a particle is moving on a circular track of radius r with angular speed W the linear speed of the particle will be?
The linear speed of the particle moving on a circular track can be found using the formula v = r * ω, where v is the linear speed, r is the radius of the circle, and ω is the angular speed of the particle.
What atomic particle do a beta particle resembles?
A beta particle is a negative electron. A positive electron is a Positron.

A high-speed electron ejected from a nucleus durng radioactive decay is called a?
an alpha particle
What is a negative electron emitted from the nucleus of an atom at high speed?
beta particle
What is negative speed in science?
Speed in science means vector (direction and velocity). Any force which lessens the vector can be considered negative speed. A spacecraft's retro rockets are a good example.
What is the most fast particle in the world?
Light is currently considered to be the fastest known particle(s) in existence. There are theoretical particles that can function well past the speed of light. One example of such theoretical particle is the Tachyon.

In that case, basically no force acts on the particle, and the particle moves at a constant speed. This constant speed may, or may not, be zero.
Is it possible to have a situation in which the speed of a particle is always zero but the average speed is not zero?
Yes, it is possible. For example, if a particle moves back and forth between two points with different speeds, such that the time spent at each point is unequal, the average speed would not be zero even though the particle's speed is zero at each point.

This radioactive particle emitted from carbon-14 has a negative charge. It contains sufficient energy to burn human skin and can pass through paper. It is a(n) particle.?
This radioactive particle emitted from carbon-14 is a beta particle. Beta particles are high-energy, high-speed electrons or positrons that carry a negative charge. They have enough energy to penetrate materials such as paper and can cause damage to human tissue, including burns.
How do you solve for the rate of change in algebra?
The rate of change is often with respect to time t. suppose that d denotes the displacement of a particle, at time t, then you can find the speed with this formula:d=rt, then to solve for r we divide both sides by t and have d/t=rIn mathematics, it is useful to distinguish between velocity and speed. First, when considering motion of a particle in a straight line, specify a positive direction so that it is a directed line. Then the velocity of the particle is positive if it is moving in a positive direction and negative if it is moving in a negative direction. The speed of the particle is the absolute value of its velocity. In more advanced work, when the velocity is a vector v, the speed is the magnitude |v| of the velocity.
