How many light years can we travel? Even if the fabric of space didn’t change over time, there are plenty of objects we can see today that could be farther away than 13.8 billion light-years. The only catch is that their light could travel for 13.8 billion light-years at most; how the objects move after […]

Who Solved the 2 body problem? The two-body problem consists of determining the motion of two gravitationally interacting bodies with given masses and initial velocities. The problem was first solved by Isaac Newton in 1687 using geometric arguments. How do you deal with two-body problems? How to Deal with the Two-body Problem Ask support from […]

What tells the cells what to do? Hidden inside almost every cell in your body is a chemical called DNA. A gene is a short section of DNA. Your genes contain instructions that tell your cells to make molecules called proteins. Do cells know they are alive? Cells don’t ‘know’ what to do – they […]

Why the tip of Allpin made sharp? The tip of an allpin is made sharp so that large pressure is exerted at the sharp end and it can be driven into with less effort. What are the two factors which does not change the vertical height of mercury column above the free surface? The density […]

What is the order of structures that oxygen passes through? Air then travels down the pharynx and larynx, through the trachea, and into the lungs. In the lungs, air passes through the branching bronchi, reaching the respiratory bronchioles. The respiratory bronchioles open up into the alveolar ducts, alveolar sacs, and alveoli.
