Are earthquake resistant buildings safe? The highest category of structural safety is that of “Earthquake Resistant — Operational”. Under this, there would be no damage to the property or any injury caused to its occupants irrespective of the magnitude of the earthquake. Which shape of plan is better in earthquake zone? Hexagons are the best, […]

What are the 2 main properties of sound?
What are the 2 main properties of sound? The two main properties of sound are frequency and amplitude. The frequency of the sound waves determines the pitch of the sound. The amplitude of sound determines the loudness. The quality of sound is affected by the pitch and the loudness. What is sound and its properties? […]
Why is crystallization done class 11?
Why is crystallization done class 11? Crystallisation of the filtrate This is done to ensure uniform evaporation and to prevent formation of a solid crust. When the volume of the solution is reduced to one half, dip one end of a glass rod in the concentrated solution and cool the drop by blowing on it. […]
Is there any time lag between action and reaction?
Is there any time lag between action and reaction? 1 Answer. At any instant in time the action and reaction forces are equal – but since as Sofia pointed out they act on different bodies, that doesn’t mean they “cancel out”: each of the bodies experiences one of the forces and accelerates accordingly. How is […]
How do you calculate channel capacity when SNR is present?
How do you calculate channel capacity when SNR is present? Hence, the channel capacity is directly proportional to the power of the signal, as SNR = (Power of signal) / (power of noise). so for example a signal-to-noise ratio of 1000 is commonly expressed as: 10 * log10(1000) = 30 dB. What is channel capacity? […]
