4 0

Answer:

Check the explanation

Explanation:

800A stands for a current of 800 Ampes and 900Hz stand for the frequency (the change in the electric field with time) of 900 Hz. In this video footage they’re trying to raise the 1 kg plate, and the major factor that is in charge in lifting the plate is the magnet field that is present. So the whole purpose of this experiment is attempting to produce a big enough magnetic force in order to lift the plate.

From the equation, we are aware that the bigger the current (800A) the bigger the magnetic force. Also, the bigger the frequency, the bigger the change in the electric field. therefore producing a bigger magnetic field and force. these figures have to be really large or larger enough to produce a powerful magnetic force strong enough to lift the plate.

Which line(s) immediately flush the output buffer?
Murljashka [212]

Answer:

lines 2,3 and 5 ( c )

Explanation:

The lines that immediately flush the output buffer are :  System.out.print("Two for the show\n"); .   System.out.println("Three to get ready"); and   System.out.flush();

making use of the new line character or printIn() statement the buffered output gets flushed therefore making autoflush true

but System.out.print() doesn't  use any flush technique so we need to flush the buffered output done by the print() statement hence we choose lines 2,3,5

Explanation:

A pound sign symbol indicates that a cell is not wide enough to display its number in Excel. However, it is noted that if you use or installed a US keyboard in your computer then hash symbol (#) is shown and the pound sign symbol is shown if you use or installed the UK keyboard layout in your computer.

Why other options are not correct.

  • An Asterisk symbol:

this symbol is used for multiplication in formula or in a cell to multiply the numbers with each other.

  • A dollar sign:

A dollar sign is used in a cell to show the currency. If you want to show the cell value as a currency. Then, you can use the dollar sign.

How was science used to make television?
Wewaii [24]

Answer:

Sir William Crookes invented the cathode ray tube in 1878, but these discoveries took many years to merge into the common ground of television. His mechanical system used a scanning disk with small holes to pick up image fragments and imprint them on a light-sensitive selenium tube. A receiver reassembled the picture.
