<span>In an experiment, the non-charged balloon moves towards the charged rod. this is applicable with the spheres.
Suppose the sphere is positively charged, the neutrally charged sphere becomes is negatively charged. The positively charged sphere causes the other sphere to be polarized, with negative charge on the side closest to the first sphere. Now the second sphere moves towards the first sphere. answer is A.</span>
Answer:
public class Window extends DesktopComponent {
public Window() {super("Window");}
public void onClicked() {System.out.println("Window selected");}
}
Explanation:
<span>PV = nRT
moles of H2 = 1/2 = 0.5
moles of He = 1/4 =0.25
T = 273 + 27
partial pressure of H2
Px1 = 0.5x0.083x300
P=12.45 atmospheres
PP of He
px1 = 0.25x0.083x300
P =6 22 atmospheres
Totla pressure = 6.22 + 12.45 = 18.68 atm</span>
Answer:
In a simplest terms,
temperature is how hot or cold an object is, while heat is the energy that flows from a hotter object to cooler one
