Explanation:
<u>Ohmic Behavior:</u>
If the current "I" produced in a conductor due to voltage "V" applied across it, is directly proportional to that voltage while the resistance of the conductor is same/constant, the material is said to be ohmic material or possessing ohmic behavior. If the resistance of a conductor doesn't remain the same due to heat, material property or any other reason, non-ohmic behavior will be observed.
<u>Thermal Expansion vs Ohmic/Non-ohmic property:</u>
For a linear conductor, thermal expansion (may be due to heat produced in result of current flow) increases length of the material due to which its resistance increases directly. Whenever the resistance increases during the flow of a current, the non-ohmic behavior arises.
R = ρL/A
where,
R=Resistance of conductor
ρ=Resistivity of material
L=length of conductor
A=Cross-sectional area of the conductor.
But,
usually this change in length and consequently change is resistance is very minor, so ignoring this change, the non-ohmic property of material will be minor too.
<u>Non-Ohmic Property:</u>
Current flows in a conductor due to flow of electrons in it. When these flowing electrons interacts with other particles (electron or atoms' nucleus) heat is produced. Due to this heat, atomic particles vibrates with more speed resulting in more hindrance/resistance in the flow of electron i.e. Resistance of material is now increased, so this will result in Non-ohmic behavior because now for the same value of applied voltage V, the flow of electron (Current) will be lesser. This will result in deviation from straight line graph as well (picture is attached)
Answer:
The velocity the air will enter the room through an opening is 20.9
Explanation:
We have to consider 2 points
Point 1 = Being away from the laboratory door
Point 2 = Gab between the floor and the laboratory door
Using the Bernoulli equation
Assuming
p1 = patm
p2 = patm + plab
patm will be cancel and both points will be at the ground level
= - у H2O * hH2O
Substituting the results
V2 = 20.9
Driver is not considered as malicious . Malicious includes computer viruses, worms, trojan horses, rootkits, spyware, adware etc.
<h3>Malicious software :</h3>
Malware is unwanted software that an unauthorized person tries to run on your computer. These are known as security threats. These include computer viruses, worms, Trojan horses, rootkits, spyware, adware, and more. Malware types include computer viruses, worms, Trojan horses, ransomware, and spyware. These malicious programs steal, encrypt and delete sensitive data. Modify or hijack core computing functionality and monitor end-user computing activity
<h3>Are Trojan Horses Malware?</h3>
A Trojan horse (Trojan horse) is a type of malware that disguises itself as legitimate code or software. Once inside the network, the attacker can take any action a legitimate user can take, including: exporting files, modifying data, deleting files or otherwise altering the contents of the device
