Answer:
The solution is as follows.
class LFilters implements Lock {
int[] lvl;
int[] vic;
public LFilters(int n, int l) {
lvl = new int[max(n-l+1,0)];
vic = new int[max(n-l+1,0)];
for (int i = 0; i < n-l+1; i++) {
lvl[i] = 0;
}
}
public void lock() {
int me = ThreadID.get();
for (int i = 1; i < n-l+1; i++) { // attempt level i
lvl[me] = i;
vic[i] = me;
// rotate while conflicts exist
int above = l+1;
while (above > l && vic[i] == me) {
above = 0;
for (int k = 0; k < n; k++) {
if (lvl[k] >= i) above++;
}
}
}
}
public void unlock() {
int me = ThreadID.get();
lvl[me] = 0;
}
}
Explanation:
The code is presented above in which the a class is formed which has two variables, lvl and vic. It performs the operation of lock as indicated above.
Answer: B webcast
Explanation:
A webcast is a technology that allows the live broadcast of an audio or video event on the Internet. It is also known as Web lecture, virtual meeting, etc. The major advantage is that it gives room for an event to have a larger reach. Webcast participation can be through PC, smart phones, tablets and other devices with quality Internet access.
Answer:
C. Hardware resources are dynamically allocated as use increases.
Explanation:
Cloud computing is a technique organisations to store and retrieve resources in a remote central database with secure access over the internet. It is able to access large data storage resources that would have cost more if they had implemented one for themselves.
A database or data centre is a online group of servers that is in a subscribed service to authorised users. Storage hardware allocation is dynamic to users, which means that another storage location in issued on every duration of subscription, making it easy to add more storage infrastructure. This defines the scalability of data centres.

The correct option is C. toward the floor.
The magnetic force on the moving negative charge acts towards the floor.
<u>Explanation</u>:
The direction of the force applied on the moving charged particle placed in the magnetic field can be determined with the help of Fleming’s Left hand rule.
The current flows in the direction opposite to the direction of electron. If the electron moves from negative terminal to positive terminal, then the current will flow from positive terminal to negative terminal.
As given, the direction of electron- South to North
So the direction of current will be- North to South
Using Fleming's Left hand rule we get the direction of force in downward direction, i.e. towards the floor.
