How many times have gravitational waves been detected?

How many times have gravitational waves been detected? It is the collaboration’s second catalogue of events, following one published in December 2018 describing their first 11 detections. In all, the observation network has now observed 50 gravitational-wave events (see ‘Cosmic clashes’). How will gravitational waves reveal a hidden universe? With gravitational waves we can study […]

How much energy does fusion release?

How much energy does fusion release? Each D-T fusion event releases 17.6 MeV (2.8 x 10-12 joule, compared with 200 MeV for a U-235 fission and 3-4 MeV for D-D fusion). On a mass basis, the D-T fusion reaction releases over four times as much energy as uranium fission. What are the cons of nuclear […]

Do plants take oxygen out of water?

Do plants take oxygen out of water? Oxygen dissolves into water from two sources: the atmosphere and from plants in the water. In the presence of sunlight, these produce oxygen through photosynthesis and release this oxygen into the pond water. At night and on very cloudy days, algae and submerged plants remove oxygen from the […]

What is the weight of a 1000 kg car?

What causes capacitors to discharge?

What causes capacitors to discharge? If a path in the circuit is created, which allows the charges to find another path to each other, they’ll leave the capacitor, and it will discharge. For example, in the circuit below, a battery can be used to induce an electric potential across the capacitor. How fast do capacitors […]

Can you filter out phosphates?

Can you filter out phosphates? Reverse Osmosis is one of the most common and effective methods used for treatment and removal of Phosphates in drinking water. The heart of the system is the Reverse Osmosis (RO) filter that removes contaminants down to 0.0001 microns – so small that only water molecules can squeeze through but […]

How do you interpret a regression summary?

How do you interpret a regression summary? The regression results comprise three tables in addition to the ‘Coefficients’ table, but we limit our interest to the ‘Model summary’ table, which provides information about the regression line’s ability to account for the total variation in the dependent variable. How is P value calculated in linear regression? […]
