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 […]

Is it OK to be single forever? Yes, it is completely fine to be single forever. As much as everyone wants their lives to have a “Happily ever after”, it generally doesn’t happen. A large amount of people in the world remain single forever, yet they can be some of the happiest people alive. Why […]

Is 1200 watts overkill for a PC? There is over kill, like me running a 1200w psu for a single videocard with no OC. So staying away from maxing out your psu is the goal. Its better to run “overkill” then it is to run “underkill” but you will start wasting power if you go […]

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? […]

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 […]

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, […]

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 […]

How can we fix climate? How You Can Stop Global Warming Speak up! Power your home with renewable energy. Weatherize, weatherize, weatherize. Invest in energy-efficient appliances. Reduce water waste. Actually eat the food you buy—and make less of it meat. Buy better bulbs. Pull the plug(s). What are the physical causes of climate change? Physical […]
