In the circuit shown above,the reading of voltmeter V will bebtado koi, |
|
Answer» Answer: Correct option is A 12 V Let us assume voltmeter is ideal:-It means voltmeter has infinite resistance and current will not flow in voltmeter. R
in UPPER branch = R eq
in lower branch. So current will GET EQUALLY divide into both branches. V A
−V B
=4×1(1) V A
−V D
=16×1(2) Subtract 2 and 1 V B
−V D
=12V A voltmeter will READ 12 V Explanation: hope it helps you dear ❤️ pta ni bhai laha se aate ye log |

A converging beam of light rats falls on a concave mirrir of focal length 20 cm. They appear to meet at a point which is 30 cm away from pole and 10 cm below principal axis. Find the location and nature of image formed |
|
Answer» Explanation: Given:-
To Find:-
Solution:-As it is given that the mirror is converging mirror . When light RAYS fall on the mirror its forms an image 30 cm away from the POLE. And also the image formed by concave mirror is real & Inverted . Firstly, we calculate the image distance Using Mirror FORMULA • 1/v + 1/u = 1/f Substitute the value we get → -1/30 + 1/u = 1/(-20) → -1/30 + 1/u = -1/20 → 1/u = -1/20 + 1/30 → 1/u = -3+2/60 → 1/u = -1/60 → u = -60 cm
Now, Calculating the Magnification • m = hi/ho = -v/u Substitute the value we get → -10/ho = -(-30)/-60 → -10/ho = -30/60 → -10/ho = -1/2 → ho = 20 cm

27) Define (a) kinetic energy (b) potential energy.Show that the change in kinetic energy of a particle is equal to the work done on it by net force. |
|
Answer» POTENTIAL energy is the energy possessed by a body due to its state of rest or opposition and kinetic energy is the energy of a body possessed by its due to the state of motion Explanation: kinetic energy depends on TWO factors the mass of the body the SPEED of the body so when the speed of a body increases , the kinetic energy also increases and the speed of the body increases by the force applied on it and if the force is more it means that the work is done by the net force |

Calculate the mass in grams for the following1. 2.25 Mole of waterII. 0.2 mole of chlorineIll. 2 mole of Oxygen |
|
Answer» Answer: 1 mole of hydrogen atoms got 1 gram, so 2 moles of them got 2 grams. 1 mole of oxygen atoms got 16 grams. Therefore, 1 mole of H2O got 18 grams. 2 moles of H2O gets you 36 grams. Chlorine GAS Cl 2, has a relative molecular mass of 71 because it is made up of TWO Cl atoms, each of Mr 35.5. 63.9976 g per mole of oxygen. From here, the answer is SIMPLE. Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g Explanation: |
