Arteries carry blood from the heart to various organs of the body. They generally carry oxygen rich blood except for pulmonary artery. Pulmonary artery is the only artery that carries carbon dioxide rich blood from heart to lungs.

Here, the sized of the object. h = 10 mm = 1 cm Size of the image h₁ = 5 mm = 0.5 cm Distance of image from the pole of mirror v = – 30 cm Let distance of ...

You must know that when we do exercise our body requires more energy. Due to exercise the body is able to get rid of excess carbon dioxide (CO₂). But remember, we get energy by the oxidation of food.

Firstly, it performs two functions: (1) makes the food alkaline and (2) breaks the fats present in food into small globules by the process of emulsification. Bile stored in the gall bladder but it is secreted by the liver and ...

% Change = Δ p/p x 100 = 4p – p/p x 100 = 300 % (2 m . 2v = 4 mv = 4 p)

Given, mass m = 2 kg, velocity v = 4 ms⁻¹. As the object is moving with a constant velocity i.e., 4 ms⁻¹. So, the acceleration of the object is zero i.e., a = 0 and according to the property ...

Given, u = 60 km/h = 60 x 5/18 m/s = 50/3 m/s, T = 1.6 s, V = 0 Average Acceleration: a = v – u/t = -50/ 3 x 1.6 = – 100/ 3 x 3.2 = – ...
