How to choose a stream as one enters class 11? Does it depend on class 10 results?

The Central Board of Secondary Education (CBSE) will declare the cbse class 10 results and cbse class 12 results on June 2 and May 24 respectively.

The light ray bends towards the normal. When a ray of light travels from an optically rarer medium to an optically denser medium, it gets bent towards the normal. Since...

The resistance of a conductor depends upon the following factors: 1. Length of the conductor 2. Cross-sectional area of the conductor 3. Material of the conductor 4. Temperature of the conductor.

Gravitational force. This force depends on the product of the masses of the planet and sun and the distance between them. 

F ∝ m1m​2 and F ∝ 1/d2 This hypothesis is not correct. The two bricks, like a single body, fall with the same speed to reach the ground at the same time...

(d) initial velocity of the object

Light ray travelling in air and entering obliquely into water is bent towards the normal; because the speed of the ray decreases in water.

The resistance of a conductor depends: (i) on its length, (ii) on its area of cross-section, (iii) on the nature of its material and (iv) on the temperature of the conductor.

(a) More the radius weaker the field. (b) Field strength is directly proportional to the number of turns in the coil.

(a) area of the hole (b) density of the liquid EXPLANATION:   The velocity of the liquid coming out of a hole in a tank is given as V =√(2gh) where h is the...
