What is meant by sinking? […]

What is momentum of body at highest point? Discussion Sravanthi -Posted on 15 Dec 15. Given: Mass of body = 2 kg, velocity = 15 m/s, θ = 70° Formula: 1) At highest point velocity = u cos θ 2) Momentum = mass x velocity. Solution: 1) At highest point velocity = 15 x cos […]

Why does more bandwidth mean more data? To transfer data, a signal must change in some way and the rate at which these changes occur influences the rate at which information can be transferred. Thus, more bandwidth corresponds to a higher maximum rate of data transfer. How do I know my Internet bandwidth? How To […]

Does specific heat depend on phase? The symbol c stands for specific heat and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC. What material has the highest specific heat? Liquid water What does CPK 1.33 mean? capable […]

What are the two types of sport psychologists? Generally, there are two different types of sport psychologists: educational and clinical. Can Exercise physiologists diagnose?

What is an example of red shift? Scientists can use redshift to measure how the universe is structured on a large scale. One example of this is the Hercules-Corona Borealis Great Wall; light takes about 10 billion years to go across the structure. How is Red Shift measured? How Do Astronomers Measure Redshift? The most […]

Why is DAB reception so poor? Much worse – because it’s an older CODEC. Internet radio feeds will be using AAC or other more efficient CODECs. The only station which broadcasts on DAB with decent quality is Radio 3, and even that is -just- OK. Generally, assuming you’ve got internet coverage, you’re better off streaming […]
