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 should I learn to draw first? The first thing that most drawing tutorials teach you to draw is shapes, starting with a sphere. After all, any object that you see around you can be constructed by using one, or a combination of, three different shapes: A circle – a sphere is a circle in […]

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? 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? 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? 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? […]

What has 7 protons and 9 Neutrons? Fluorine Which is heavier neutron or proton? High on this list are the masses of subatomic particles. Dozens of particles are known to physicists, but the most familiar are the constituents of atoms: electrons, protons and neutrons. The neutron is very slightly heavier than the proton, by about […]

Why do bulbs in a series circuit get dimmer? Why bulbs in series are dimmer The current going through them is smaller because two bulbs in series have a higher resistance than a single bulb. Each charge only gives up some of its energy in each bulb, i.e. the p.d. across each bulb is smaller. […]

What is hydrogen bonding What are its types explain with examples? Hydrogen bond is a electrostatic attraction between a hydrogen atom which is bond to a more electronegative atom such as Nitrogen, Oxygen, fluorine. These are two types of hydrogen bonds :- 1) Intermolecular Hydrogen bonding :- It occurs between two separate molecules. Eq :- […]

Can you leave garden hoses out all winter? A: Hoses can be stored outside as long as you make sure to drain all of the water from the hose. Hoses can be drained easily by running them over a tall place where gravity forces water to exit the hose. This ensures that the hose won’t […]
