What are contour lines for Class 7?
What are contour lines for Class 7? (i) Contour lines are isolines of height. (ii) These are drawn by joining the places of equal altitude. (iii) These help in identification of land forms and their altitude from sea level. (iv) These lines also help us to understand the nature and direction of the slope. What […]
What does velocity relative to the ground mean?
What does velocity relative to the ground mean? The velocity of the object measured relative to the ground is called the ground speed. Again, this is a vector quantity. Airspeed is the vector difference between the ground speed and the wind speed. On a perfectly still day, the airspeed is equal to the ground speed. […]
Is nitrogen-14 an isotope?
Is nitrogen-14 an isotope? Nitrogen-14 is one of two stable (non-radioactive) isotopes of the chemical element nitrogen, which makes about 99.636% of natural nitrogen. Nitrogen-14 is one of the very few stable nuclides with both an odd number of protons and of neutrons (seven each) and is the only one to make up a majority […]

Can a car run on jet fuel?
Can a car run on jet fuel? Jet fuel can actually be used in cars, but only in diesel engines. Kerosene jet fuel and diesel are actually similar enough to allow for cross-functionality and would provide a similar performance. Both are derived from crude oil, and both run their respective engines on combustion. How much […]
