Why is it difficult for a high speed car to negotiate an unbanked turn? (a) A huge force is pushing the car outward. (b) The magnitude of the friction force might not be enough to provide the necessary radial acceleration. A car negotiating an unbanked road at high speed is actually accelerating as the direction […]
What does the bubbling indicate?
What does the bubbling indicate? When substances are put in the same container like, CaCO3 and HCl . A reaction occurs and bubbles escape the container (effervescence). These bubbles are actually gas fumes, and this shows that a new gaseous product is formed. Here, bubbling indicates our chemical reaction. What are the bubbles that you […]
What is the source of energy for the life in deep sea ocean trenches where sunlight does not reach?
What is the source of energy for the life in deep sea ocean trenches where sunlight does not reach? Answer: Instead of sunlight, vent life relies on hydrogen sulfide – more commonly known as rotten egg gas and toxic to most land-based life. In a process called chemosynthesis, specialized bacteria create energy from the hydrogen […]

How do you calculate work done efficiency?
How do you calculate work done efficiency? The work efficiency formula is efficiency = output / input, and you can multiply the result by 100 to get work efficiency as a percentage. This is used across different methods of measuring energy and work, whether it’s energy production or machine efficiency. What is the difference between […]
Why is there a delay when changing channels?
Why is there a delay when changing channels? When there is a delay while changing channels before a picture appears, it is likely that the Set Top Box is having trouble locating a signal due to weak signal strength. How do I change channels without a remote? How to Change the TV Channels Without a […]
Is Sodium naturally occurring?
Is Sodium naturally occurring? Food and drink contents. Sodium occurs naturally in most foods. The most common form of sodium is sodium chloride, which is table salt. Milk, beets, and celery also naturally contain sodium, as does drinking water, although the amount varies depending on the source. Which fruit has high-sodium? Food Sources of Sodium […]
What is a disadvantage of hydrogen fuel cells?
What is a disadvantage of hydrogen fuel cells? There are disadvantages to using hydrogen-oxygen fuel cells in cars. These include: hydrogen is in the gas state at room temperature and pressure, so it is difficult to store in the car. fuel cells and electric motors are less durable than petrol engines and diesel engines, so […]
How do igneous rocks look like?
How do igneous rocks look like? Extrusive, or volcanic, igneous rocks look dull and do not sparkle much because they are fine grained. These crystals make a coarse-grained igneous rock called plutonic, or intrusive, igneous rock because the magma was intruded into cracks deep under the earth’s surface. What type of rock is granite? Granite […]
