Why is some food heated unevenly? Why Your Food Is Heating Up Unevenly Microwaves are sending radio waves toward your food, rather than heating it from underneath it like gas ovens. And people tend to pile leftovers with the densest part in the middle, which is why the outer edges will heat up, leaving 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 astrology sign is the moon in right now? Aries What is Lilith in astrology? In an astrology chart, Black Moon Lilith represents a person’s primitive impulses and behavior in their rawest form. It reveals our repressed sexuality, together with what makes us feel most vulnerable; it expresses the dark side of one’s personality, buried […]

Can firewood be too dry? It’s not something that most people complain about very often, but yes, wood can be too dry and burn faster than would be the case at an optimal 10-15% MC. What is the longest burning firewood? Hardwoods such as maple, oak, ash, birch, and most fruit trees are the best […]

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? […]

How Global Weather is monitored? Scientists, volunteer observers, and automated instruments from around the world measure climate variables at Earth’s surface and above. Some of the data collected include air chemistry, temperature, precipitation, cloud cover, and wind speed. Who uses weather maps? It can show temperature, cloud coverage, rain or snow, wind, air pressure, humidity, […]

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 […]

What is the best definition of reflection? 1 : an instance of reflecting especially : the return of light or sound waves from a surface. 2 : the production of an image by or as if by a mirror. 3a : the action of bending or folding back. b : a reflected part : fold. […]

What happens to the resistance of wire if it is stretched? The resistance of a wire is inversely proportional to its area and directly proportional to its length. When the length is tripled then resistance will also become three times. If The wire is stretched 3 times the original length, the cross-section of the wire […]
