Recently, Frank’s computer has slowed down dramatically. He has also noticed that the time on the computer is not accurate. Fran
Paraphin [41]

Answer:

a. Zombie

Explanation:

Zombies- A cracker — a computer hacker who intends mischief or harm — secretly infiltrates an unsuspecting victim’s computer and uses it to conduct illegal activities. The user generally remains unaware that his computer has been taken over — he can still use it, though it might slow down considerably. As his computer begins to either send out massive amounts of spam or attack Web pages, he becomes the focal point for any investigations involving his computer’s suspicious activities. In one case of zombies it was found that over 1.5 million computers were affected in an attack.

A proton and an electron enter perpendicular to the direction of the magnetic field. The speed of the proton is twice the speed
Nezavi [6.7K]

Answer:

The force on the proton will be twice in comparison with the force experienced by the electron.

Explanation:

The magnetic force acting on the moving charge particle is perpendicular to the velocity as well as the magnetic field. The factors upon which the magnitude of the force is depending and proportional are as follows:

1 Magnitude of the charge particle.

2 Magnitude of the velocity of moving charge.

3 Magnitude of magnetic field.

4 Sine of angle between the velocity and magnetic field.

As far as direction is concerned, it can be find out by right hand rule.

Lets consider,

Speed of electron = Ve

Speed of proton vp= 2ve

Magnitude of the force F = qvBsin∅

Force acting  on electron Fe = qe.ve.Bsin∅

Force acting on proton Fp = qp.vp.Bsin∅

                                       Fp = -2 qe.ve.Bsin∅

                                       Fp = -2Fe

Negative sign shows the direction of Force on proton is opposite to the direction of force on electron.

Which best describes an example of an n-type semiconductor?
nata0808 [166]
An N-Type semiconductor will always have an excess electron which is more famous for the term valence electrons. It is one of the part which makes a p-n junction the structure of a diode a basic type of semiconductor device. A P-type semiconductor on the other hand has missing electrons or most widely known as valence holes. When applied a voltage bias of correct polarity and intensity between both ends of the junction you are able to close the gap between the junction allowing the excess valence electron to pass through the p type material inducing current with process, in application lighting up the diode.
