What is the purpose of the iodine clock reaction? The “clock reaction” is a reaction famous for its dramatic colorless-to-blue color change, and is often used in chemistry courses to explore the rate at which reactions take place. The color change occurs when I2 reacts with starch to form a dark blue iodine/starch complex. Why […]
Why do most students prefer last minute?
Why do most students prefer last minute? Why students study last minute Procrastination and the perception that they perform better under pressure and cramming “just works better for them”, was also among the top reasons for last-minute study habits.

What are 2 ways viruses can reproduce?
What are 2 ways viruses can reproduce? There are two processes used by viruses to replicate: the lytic cycle and lysogenic cycle. Some viruses reproduce using both methods, while others only use the lytic cycle. In the lytic cycle, the virus attaches to the host cell and injects its DNA. How virus is created? Viruses […]
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 […]
Why is water solubility important to life?
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, […]
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? […]
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 […]
