Does a catalyst change the rate? A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the reaction. A catalyst works by providing a different pathway for the reaction, one that has a lower activation energy than the uncatalyzed pathway. Does a catalyst decrease the rate constant? An […]
What is the difference between length breadth and height?
What is the difference between length breadth and height? The term height refers to how tall is an object. whereas length refers to how long is the object.

Can cell phones cause nerve damage?
Can cell phones cause nerve damage? Too much cell phone use can lead to overextending nerves, causing what doctors call “cell phone elbow.” Orthopedic specialists are reporting cases of “cell phone elbow,” in which patients damage an essential nerve in their arm by bending their elbows too tightly for too long. Can cell phones cause […]
Why do toilets flush backwards in Australia?
Why do toilets flush backwards in Australia? Because of the rotation of the Earth, the Coriolis effect means that hurricanes and other giant storm systems swirl counter-clockwise in the Northern Hemisphere, and clockwise in the Southern Hemisphere. In theory, the draining water in a toilet bowl (or a bathtub, or any vessel) should do the […]
What causes a forward pitch?
What causes a forward pitch? Forward pitch occurs whenever you apply the brakes, shifting the balance away from the back of the vehicle and into the front wheels. As the vehicle’s weight shifts forwards, your rear wheels may lose connection with the road surface and swing out to the side as you turn. What is […]
Why is G universal constant?
Why is G universal constant? G is called universal constant becuase its value remains the same throughout the universe and is independent of masses of the objects. Answer: Capital G will be constant become the value of the G will be constant anywhere in the Universe. Why is there no life on moon? The Moon’s […]
What does the formula of an ionic compound tell you?
What does the formula of an ionic compound tell you? Answer: The overall ionic formula for a compound must be electrically neutral, meaning it has no charge. When writing the formula for the ionic compound, the cation comes first, followed by the anion, both with numeric subscripts to indicate the number of atoms of each. […]
What is the fastest way to discharge a capacitor?
What is the fastest way to discharge a capacitor? The quickest way to discharge a capacitor is to touch the two terminals of the capacitor together, as is shown below. Again, this is the quickest way to discharge a capacitor. However, it’s only advised that you do this for capacitors storing a very low voltage. […]
What happens if groundwater is overused?
What happens if groundwater is overused? Over development of groundwater environment could lead to drying up of wells and decrease in water levels. It could also result in drying up of streams and lakes apart from causing induced pollution, Arun P.R., a scientist at the Centre for Water Resources Development and Management, Kunnamangalam, says. Why […]
What removes gunpowder from hands?
What removes gunpowder from hands? As time passes after discharge, GSR particles can be removed from the hands by contact with other objects or by hand washing. What two tests are performed to detect GSR on clothing? Chemical test enhancement on GSR involves the use of Modified Griess test and Lunges reagent test to detect […]
