What height of water is supported by atmospheric pressure what height of mercury? 760 mm Why is water not used as barometric liquid? Solution. Water is not a suitable barometric liquid because: (i) The vapour pressure of water is high, so its vapours in the vacuum space will make the reading inaccurate. (ii) Water sticks […]

How many grammes makes 1kg? 1,000 grams How much is half 1kg? Half of one kilogram= 1000/2 = 500 grams. Hence if you take a half of this then it will be 1000÷2= 500gm. 500 grams in half a kilogram. 1 kilogram=1000 grams. What is half of 1kg? 500g How many cups is half kilo? […]

Does sulfur break easily? Sulfur is a solid, which means you can hold it and touch it, but it is known as a nonmetal, meaning it is not made up of metal. It is recognizable because of its pale yellow color. If you touch it, it is soft and can easily break with your fingers. […]

What is the main source of energy for the water cycle? The sun is what makes the water cycle work. The sun provides what almost everything on Earth needs to go—energy, or heat. How do you write a water cycle? Write a note on water cycle Answer: The water cycle, or hydrological cycle, is the […]

Is there a machine that turns carbon dioxide into oxygen? Now, researchers at Caltech claim to have created a reactor that can turn carbon dioxide into molecular oxygen, which could help us fight climate change here on Earth or generate oxygen for life in space. Oxygen is one of the biggest hurdles to human space […]

What is the equivalent resistance between points A and B 2 points? Answer. Rt=2+2+1=5 ohm. What is equivalent resistance in parallel? If the two resistances or impedances in parallel are equal and of the same value, then the total or equivalent resistance, RT is equal to half the value of one resistor. Which of the […]

What type of force is pushing a box? Forces Due to Friction (and Newton’s Third Law) When you push a heavy box, it pushes back at you with an equal and opposite force (Third Law) so that the harder the force of your action, the greater the force of reaction until you apply a force […]

How did the force get out of balance? The idea of balance of the Force, a central tenet of the Jedi Order, refers to the ideal state in which the Force exists in nature, i.e. as the light side. The presence of the dark side corrupts and destroys this natural balance, and the Jedi viewed […]

At what angle two forces p Q and PQ Act so that resultant is √ 2p 2 Q 2? Thus, the angle of inclination between the forces must be 60°. At what angle should the two vectors 2f and act so that the resultant force is? Answer: Let a and b are two vectors making […]

How do you find the missing resistance? If you know the circuit’s total current and voltage, you can use Ohm’s Law R = V/I to find the total resistance, then the formula for resistors in parallel to solve for the missing resistor value. What happens when resistors are connected in parallel? When resistors are connected […]
