Activity 12.1 asks us to correlate voltage and current across a resistance using a different number of batteries. Observation: On increasing the number of batteries, the potential difference, as well as the current across the resistance, increases proportionally. Explanation: When we increase the number of batteries across a resistance, we increase the potential difference across the resistance. Potential difference is directly proportioned to the current flowing through it. As a result, we see an increase in the reading of ammeter as well as that of the voltmeter. Consider Potential difference as pressure on water and current as a flow of water. If we increase the pressure, it will result in an increase in the flow of water. The same thing happens with the current also. We call this as Ohm’s law. Ohm’s law state that at a fixed temperature the voltage across the resistance is directly proportional to the current flowing through it. V∝I when Temperature and resistance are constant. i.e. V=IR Conclusion: On increasing the potential difference across a resistance we see an increase in the current, it proves that V∝I i.e. Ohm’s law. Calculation: experiment to demonstrate ohm's law On an increase in voltage, current across the resistance also increases

Resource planning is a technique or skill of proper or judicious use of resources. ” Resource planning is a complex process which involves : (i) Identification and inventory of resources across the regions of the country. This involves surveying, mapping, qualitative and quantitative estimation and measurement of the resources. (ii) Evolving a planning structure endowed with appropriate technology, skill and institutional set up for implementing resource development plans. (iii) Matching the resource development plans with overall national development plans.

Answer Let 0.2x+0.3y=1.3 ....(1) 0.4x+0.5y=2.3 ....(2) Multiply eqn(1) by 10 we get 2x+3y=13 ....(3) Multiply eqn(2) by 10 we get 4x+5y=23 ....(4) Solving equations (3) and (4) 5×(3)⇒10x+15y=65 3×(4)⇒12x+15y=69 Subtracting we get 12x+15y−10x−15y=69−65=4 or 2x=4 or x=2 Substituting x=2 in eqn(3) we get 2x+3y=13⇒2×2+3y=13 or 3y=13−4=9 or y=3 Hence x=2,y=3

When light rays strick on a concave mirror after reflection rays meet at a point this point is known as principal focus of concave mirror

Saloni Harinkhede 4 years, 2 months ago

(i) The principal focus of a concave mirror is a point on its principal axis to which all the light rays which are parallel will converge after reflection from the concave mirror. When an object is placed at infinite distance from the mirror, the rays of light coming from the object will be parallel to the principal axis as shown in the figure. After reflection from a concave mirror, the rays will converge to the focal point of the mirror which is denoted by point F in the image. (ii) The focal length of a concave mirror is the distance between the pole of the mirror denoted by point P in the image to the focal point of the mirror. Hence it is the distance between points P and F. Note For a concave mirror, whose radius of curvature lies in front of the concave mirror, the value is taken negative and so is the focal length of the mirror according to the convention of the Cartesian coordinate system. We must be careful to not mix the focal point and the centre of curvature of the mirror as the centre of curvature is approximately twice the focal length of the mirror.

4052 and 12579 division algorithm

Posted by Sakshi Madheshiya 4 years, 2 months ago

CBSE > Class 10 > Mathematics

1 answers

Sia ? 4 years, 2 months ago

According to Euclid’s Division Lemma if we have two positive integers a and b, then there exist unique integers q and r which satisfies the condition a = bq + r where 0 ≤ r ≤ b.

HCF is the largest number which exactly divides two or more positive integers.

Since 12576 > 4052

12576 = (4052 × 3) + 420

420 is a reminder which is not equal to zero (420 ≠ 0).

4052 = (420 × 9) + 272

271 is a reminder which is not equal to zero (272 ≠ 0).

Now consider the new divisor 272 and the new remainder 148.

272 = (148 × 1) + 124

Now consider the new divisor 148 and the new remainder 124.

148 = (124 × 1) + 24

Now consider the new divisor 124 and the new remainder 24.

124 = (24 × 5) + 4

Now consider the new divisor 24 and the new remainder 4.

24 = (4 × 6) + 0

Reminder = 0

Divisor = 4

HCF of 12576 and 4052 = 4.

The aftermath of World War I saw drastic political, cultural, economic, and social change across Eurasia, Africa, and even in areas outside those that were directly involved. Four empires collapsed due to the war, old countries were abolished, new ones were formed, boundaries were redrawn, international organizations were established, and many new and old ideologies took a firm hold in people's minds. World War I also had the effect of bringing political transformation to most of the principal parties involved in the conflict, transforming them into electoral democracies by bringing near-universal suffrage for the first time in history, as in Germany (1919 German federal election), Great Britain (1918 United Kingdom general election), and Turkey (1923 Turkish general election)
