Final kinetic energy will be equal to (Initial kinetic energy) plus (work that you do to turn it around).
KE = 1/2 m V2
Initial KE = 1/2 (0.026) (13)2 with 'V' pointing left.
Final KE = 1/2 (0.026) (49)2 with 'V' pointing right.
You have to supply the difference = 1/2 (0.026) (62)2 = 49.972 kg-m2/s2 = 49.972 newton-m
= 49.972 joules
750 J
537.5 J
The change in velocity is (\Delta v = 49 , m/s - (-13 , m/s) = 62 , m/s). The work done is given by (W = \frac{1}{2} m (\Delta v)^2), where (m) is the mass of the particle. Substituting the given values, the net work required is (W = \frac{1}{2} \times 26 , g \times (62 , m/s)^2).
When a particle is moving in a circular motion at a constant speed, the work done by the particle is zero. This is because work is defined as force applied over a distance in the direction of the force, and in circular motion, the force and displacement are perpendicular to each other, resulting in no work being done.
In the scientific definition of work, magnetic and electric fields can do work on charged particles that are moving through them. The work done is based on the force exerted by the field on the particle and the distance over which the particle is displaced.
If the net work done on a particle is zero, it means that the kinetic energy of the particle is not changing. Therefore, the speed of the particle remains constant.
When a charged particle is moved along an electric field line, it will experience a force in the direction of the field line. The work done on the particle depends on the distance it moves and the strength of the field. If the particle moves perpendicular to the field lines, then no work is done by the field.
If displacement of a particle is zero in a uniform circular motion, then the distance travelled by that particle is not zero, kinetic energy is constant, speed is constant and work done is zero
The past participle for the word "do" is "done."
If you do not have a problem moving you face or nose when the septum is done right.
cause you cant get the job done right
The past participle of do is 'done'.
11
It is done by moving the decimal point 7 places to the right, to give: 94000000
If displacement of a particle is zero in a uniform circular motion, then the distance travelled by that particle is not zero, kinetic energy is constant, speed is constant and work done is zero
If the net work done on a particle is zero, it means that the kinetic energy of the particle is not changing. Therefore, the speed of the particle remains constant.
A particle count test is usually done using a hand held particle counter. The purpose is to sort aerosolized particles into different aerodynamic sizes and then count in units of x/cubic meter of air. Airborne particle counts are done to monitor clean-room atmospheres and air environments in the workplace.
A conservative force is not path dependent. A conservative force is a force with the property that the work done in moving a particle between two points is independent of the taken path.
possibly a bad brake...you should get all brakes done
A law that is not done right is a law that is untrue. This is usually when a law that was not passed.
