What is the effect on the drift velocity of free electrons by decreasing the length and the temperature of wire?
As we know , resistance(R) is directly proportional to length(L) of conductor and resistence(R) is inversely proportional to current (I) and
I=nAqv (v is drift velocity)
So , if we decrease the length of the conductor , resistance of the conductor will decrease and current(I) will increase and drift velocity of free electrons will increase .
And as we know resistance and temperature have direct relation so , by decreasing the temperature resistence will decrease and current will increase . So drift velocity will increase .

What is the effect on accelerationif we decreasing velocity?
If velocity is decreasing, acceleration is in the opposite direction of the initial velocity. If the velocity is decreasing at a constant rate, the acceleration is negative, causing deceleration. If the velocity is decreasing while changing direction, the acceleration may be a combination of negative and positive components.
The second postulate of kinetic theory states that particles move in random straight lines at various velocities and in all directions Predict the effect of decreasing the temperature of the system o?
Decreasing the temperature of the system will result in the particles slowing down and having reduced kinetic energy. This will cause the particles to move less vigorously and with lower velocities. The decreased temperature will also lead to a reduction in the average kinetic energy of the particles.
Does an increase in velocity or an increase in mass have a greater effect on momentum?
An increase in velocity has a greater effect on momentum than an increase in mass. This is because momentum is directly proportional to velocity, while mass only has an indirect effect on momentum through its influence on velocity.
Does horizontal velocity effect the rate of vertical velocity?
No, horizontal velocity does not affect the rate of vertical velocity. Each component of velocity (horizontal and vertical) is independent of the other. They act separately to determine the motion of an object.
What are three ways in which the velocity of an object may change when the forces on the object are unbalanced?
doing some homework? A net force vector/imbalance can either increase velocity (positive acceleration), decrease velocity (negative acceleration) or effect zero acceleration (perpendicular).
What is the effect on accelerationif we decreasing velocity?
If velocity is decreasing, acceleration is in the opposite direction of the initial velocity. If the velocity is decreasing at a constant rate, the acceleration is negative, causing deceleration. If the velocity is decreasing while changing direction, the acceleration may be a combination of negative and positive components.
What is the effect of decreasing the temperature of the pH of water?
Decreasing the temperature of water the value of pH increase.
What is meant by isotopic effect?
the variton of transition temperature with respect to mass of iostopic electrons
Discuss effect of temperature on the velocity of sound?
Scroll down to related links and look at "Speed of sound - Wikipedia". There is a table of the effects of the temperature on sound. Don't say "velocity of sound", call it "speed of sound".
How does mass effect velocity?
It doesn't. But velocity does effect mass : as velocity increases, mass increases.
What has an effect on air pressure?
gas composition of atmosphere (including water vapour); altitude; temperature; and wind velocity.
What has an effect on earths air pressure?
gas composition of atmosphere (including water vapour); altitude; temperature; and wind velocity.
How do you determine the velocity of an electron?
X-rays are reflected by electrons. The shift in frequency/wavelength of the reflected X-ray compared to the original X-ray (Doppler effect) can be used to measure the speed of the electrons.
What has the author David William Cornelius written?
David William Cornelius has written: 'The study of the velocity of electrons in the photo-electric effect, as a function of the wave-lengths of the light' -- subject(s): Electrons, Radiation
In an arithmetic sequence if the difference value is negative what is the effect?
It creates a decreasing sequence.
What is corrected effective temp index?
It is an index of thermal comfort & combines effect of temperature,humidity,velocity of air & mean radiant heat.
How is a rocket able to escape earth's gravity?
It can never escape it entirely. It can, however, travel fast enough that the increasing distance outweighs the effect of the decreasing gravity. On earth, this velocity is about seven miles per second.
