Why is water solubility important to life? Water is called the “universal solvent” because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, […]
Which is most important to ensure the largest light collecting power of a telescope?
Which is most important to ensure the largest light collecting power of a telescope? The most important of all the powers of an optical telescope is its light-gathering power. This capacity is strictly a function of the diameter of the clear objective—that is, the aperture—of the telescope. How many times longer than your eye can […]
What is the Dyson motor called?
What is the Dyson motor called? Dyson digital motor Does Dyson use brushless motor? The Dyson digital motor V4 is a brushless DC motor – with a lot of on-demand power. Brushless motors can offer great amounts of torque per watt and reduce wear and tear. The most incredible thing is the speed it can […]
How fast can an object fall in water?
How fast can an object fall in water? 5.04 m/s How ripples are formed? Formation. Symmetrical ripples form as water molecules oscillate in small circles. The water molecules continue to do this to a depth equal to 1/2 the wavelength. The water molecule traveling in a circular pattern interacts with the sediment on the floor […]
What is the most economical central heating system?
What is the most economical central heating system? For most of us, the cheapest heating system is going to be mains gas fuelled. If you’re living off the grid, LPG is the most cost effective heating option. If you take full advantage of Economy 7 electricity tariffs, you may be able to match LPG systems […]
What is the minimum transmission bandwidth?
What is the minimum transmission bandwidth? Minimum Transmission Bandwidth (Using Ideal Nyquist Pulses) As seen the bandwidth required is (Rb)/2 (∵Rb =1/Tb) for the Nyquist pulse shown above. It is the peculiar scheme of overlapping signals that results in minimum transmission bandwidth. How many signaling levels are needed? How many signal levels do we need? […]

Would a propeller work in space?
Would a propeller work in space? Turbine engines and propellers use air from the atmosphere as the working fluid, but rockets use the combustion exhaust gases. In outer space there is no atmosphere so turbines and propellers can not work there. This explains why a rocket works in space but a turbine engine or a […]

Is the image in a mirror real or virtual?
Is the image in a mirror real or virtual? Key Points Reflected images can be either real or virtual. In a plane mirror, the images are virtual. The virtual images in a plane mirror have a left-right inversion. Why are real images always inverted? Real image is found when the rays of light converge at […]
