Work = (force) x (distance)
Work = (60N) x (5 m)
Work = 300 N-m
<em>Work = 300 Joules</em>
Answer:
a. The electric field lines are linear and perpendicular to the plates inside a parallel-plate capacitor, and always from positive plate to the negative plate. If a positive charge is released near the positive plate, then it will follow a linear path towards the negative plate under the influence of electrostatic force, F = Eq, where q is the charge of the particle. The electric field inside a parallel plate capacitor is constant and equal to
This can be calculated by Gauss' Law.
A positive charge always follow the electric field lines when released. Another approach is that the positive plate repels the positive charge and negative plate attracts the positive charge. Therefore, the positive charge follows a path towards the negative charge.
b. The particle moves from the higher potential to the lower potential. The direction of motion is the same as the direction of the force that moves the particle, so the work done on the particle by that force is positive.
<u>Answer </u>
Wind
Water movement
A hill
<u>Explanation. </u>
The question does not specify it is the acceleration of what is to be accelerated. So my answer will be general. Acceleration is the change of velocity with time.
Wind can cause acceleration of sound. If the sound is travelling in the direction of sound, its speed wound increase. The reverse is also true.
Water movement can also cause acceleration. When a bout is moving in the direction of water movement, then it will be expected that the resultant speed of the bout to be higher. If the bout was moving against the water movement, its speed would be decreased.
A hill would reduce the speed of a moving vehicle. This is also an acceleration that is negative (deceleration).
A stop light and a flat road cannot cause acceleration.
As far as I remember the nuclear power is derived from a nuclear <span>A)fusion </span>chain reaction. I think it's correct.
