Answer:
JTextField
Explanation:
JTextField is a Swing control which can be used for user input or display of output. It corresponds to a textfield and can be included with other controls such as JLabel, JButton,JList etc. on a comprehensive user interface which is application dependent. JTextField supports a read-write mode where the user can enter a value and it also supports a read-only mode which can be used to display non-editable output to the user.
Answer:
Time taken to travel from one track to the next = 0.08ms
Initial track= 15 0
4 (15-4)*(0.08)= 0.88
40 (40-4)*(0.08)= 2.88
35 (40-35)*(0.08)= 0.4
11 (35-11)*(0.08)= 1.92
14 (14-11)*(0.08)= 0.24
7 (14-7)*(0.08)= 0.56
----------------------------------------------
Total seek time=0.88+2.88+0.4+1.92+0.24+0.56=6.88ms
Explanation:
We caculate the seek time for each request, and then add them together to find the total seek time. The final track number for the current request becomes the current track of next request, and this process is repeated till the last request is processed.
Straw man
eg. "Senator Jones says that we should not fund the attack submarine program. I disagree entirely. I can't understand why he wants to leave us defenseless like that."
Ad hominem
eg. “How can you argue your case for vegetarianism when you are enjoying your steak?”
Over simplication
eg. President Bush wants our country to trade with Fidel Castro's Communist Cuba. I say there should be a trade embargo against Cuba. The issue in our election is Cuban trade, and if you are against it, then you should vote for me for president.
Bandwagon
eg. Everyone is selfish; everyone is doing what he believes will make himself happier. The recognition of that can take most of the sting out of accusations that you're being "selfish." Why should you feel guilty for seeking your own happiness when that's what everyone else is doing, too?
Black or white
eg. Well, it's time for a decision. Will you contribute $20 to our environmental fund, or are you on the side of environmental destruction?
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.
