What is the purpose of the iodine clock reaction?

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. Is it good to study last minute? The last 24 hours before an exam can be […]

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 […]

What are the dangers of space?

What are the dangers of space? 5 Hazards of Human Spaceflight Radiation. Isolation and confinement. Distance from Earth. Gravity (or lack thereof) Hostile/closed environments. Human research essential to space exploration. Do animals know God? There is no evidence that any non-human animals believe in God or gods, pray, worship, have any notion of metaphysics, create […]

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 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? […]
