Place two plane mirrors at an angle of 90° to each other. Place a small object between them. Images will be formed in both mirrors.How many images do you see? |
|
Answer» 3 Images will be FORMED. Explanation:If you place two mirror at an ANGLE, rather than ONE multiple images are formed. This is because the image formed in the first mirror acts as the object for the second mirror. In this case, if you place the mirrors at right angle (90°), then the formula 360/n -1 is used, where n is the angle between the mirror.Here, n= 90. So,360/90–1=4–1 = 3.Therefore, 3 images will be formed.Hope this answer HELPED. |

Initial pressure of XY, is 600 mm Hg. pressure at equilibrium is 800 mm Hg.volume of system to remain constant, thK is(1) 50(3) 20(2) 100(4) 400... pressure of COCI. is 1000 |
|
Answer» XY 2 DISSOCIATES as:XY 2 (g)⇌XY(g)+Y(g)Initial pressure of XY 2 is 600 mm Hg. The total pressure at EQUILIBRIUM is 800 mm Hg.Let X mm Hg of XY 2 dissociates to reach equilibrium. x mm Hg of XY and x mm Hg of Y will be formed at equilibrium. 600−x mm Hg of XY 2 will be present at equilibrium.Total pressure =(600−x)+x+x=600+x mm Hg But total pressure =800 mm Hg 600+x=800 or x=200Thus, the equilibrium pressures areP XY 2 =600−x=600−200=400 mm HgP XY =x=200 mm HgP Y =x=200 mm Hg Assuming volume of system to remain CONSTANT, the value of K p = P XY 2 P XY P Y K p = 400200×200 K p =100 mm |

Reproduction कया होता है |
| Answer» REPRODUCTION) द्वारा कोई जीव अपने ही सदृश किसी दूसरे जीव को जन्म देकर अपनी जाति की वृद्धि करता है। जन्म देने की इस क्रिया को जनन कहते हैं। जनन जीवितों की विशेषता है। जीव की उत्पत्ति किसी पूर्ववर्ती जीवित जीव से ही होती है। निर्जीव पिंड से सजीव की उत्पत्ति नहीं देखी गई है। संभवत: विषाणु (VIRUS) इसके अपवाद हों । जनन के दो उद्देश्य होते हैं एक व्यक्तिविशेष का संरक्षण और दूसरा जाति की शृंखला बनाए रखना। दोनों का आधार पोषण है। पोषण से ही संरक्षण, वृद्धि और जनन होते हैं। | |
