What is the efficiency of an engine that gives off 70 percent thermal energy?
It is not a good efficiency engine.
Write a program by using java to draw the colored International Olympic logo in the middle of the window?
public class olimp extends JFrame { public void paint (Graphics g){ g.setColor(Color.BLUE); g.drawOval(220, 200, 70, 70); g.setColor(Color.BLACK); g.drawOval(290, 200, 70, 70); g.setColor(Color.RED); g.drawOval(360, 200, 70, 70); g.setColor(Color.YELLOW); g.drawOval(240, 230, 70, 70); g.setColor(Color.GREEN); g.drawOval(320, 230, 70, 70); } } public static void main(String[] args) { // TODO code application logic here olimp t=new olimp(); t.setSize(600,400); t.setVisible(true); }
What is the efficiency of an engine that gives off 70 percent thermal enery?
If this, ie 70%, is the total energy loss, it follows that the engine is producing 30% useful energy, so that is its thermodynamic efficiency.
What is the chemical formula for Fe2O3?
That is the chemical formula. The name would be iron (III) oxide, or ferric oxide in the old system.
Another way of saying that the output is 70 percent of the signal input at cutoff frequency is that the output is up or down dB at frequency cutoff?
If the output power is 70% of the input power, then the output is roughly 1.55 dB downcompared to the input.If the voltage at any point of the output waveform is 70% of the voltage at the same pointon the input waveform, and the input and output impedance are equal, then the output is3.1 dB down (rounded) compared to the input.
