Answer:
v = -227.785 m/s
Explanation:
The electric field exerts the following force on the electric particle:
F = qE


The magnetic field exerts the following force on the particle::
F = qvB


Total force acting is:
F = qvB + qE


v = -227.785 m/s
Answer:
Power = 1200 [W].
Explanation:
The efficiency of an electrical equipment is defined as the relationship between the power realized, over the power that is consumed. For this case, they give us the data of consumed power and efficiency in this way we can calculate the power that the equipment performs.
![Efficency=\frac{Power_{done}}{P_{consumed}}\\0.8 = \frac{Power_{done}}{1500} \\Power_{done}=1500*0.8\\Power_{done} = 1200 [W]](https://tex.z-dn.net/?f=Efficency%3D%5Cfrac%7BPower_%7Bdone%7D%7D%7BP_%7Bconsumed%7D%7D%5C%5C0.8%20%3D%20%5Cfrac%7BPower_%7Bdone%7D%7D%7B1500%7D%20%20%5C%5CPower_%7Bdone%7D%3D1500%2A0.8%5C%5CPower_%7Bdone%7D%20%3D%201200%20%5BW%5D)
This means that of the 1500 [W], 1200 [W] are actually used to get the job done. This is established by means of the first law of thermodynamics.
Answer:
It saves time and cost nothing than to get the same information that would cost money.
Answer:
1.47*10^{-8}s
Explanation:
You first calculate the distance traveled by the electron:

Next, you calculate the relative speed as measure by an observer in the positron, of the electron:

with this relative velocity you calculate the time:

<span>A. the distance between them
</span>inversely proportional to the square of distance according to
F = Gm1m2/d^2
