What are electrical impulses in the brain called? Neurons carry electrical signals, called nerve impulses, which can be passed on to other neurons. This continous buzzing of signals allows you to think, feel, and move. The neurons consist of a cell body sprouting with dendrites, which receive signals from other neurons. What causes electrical impulses […]
Why self driving cars are not safe?
Why self driving cars are not safe? Self-driving cars may not be able to navigate through heavy rain or snowstorm that could hide or distort the painted lines on roads and highways. This can make autonomous navigation systems, if not useless, at least, erratic. Additionally, self-driving cars may give drivers a false sense of security. […]
Why is the SI system used in science?
Why is the SI system used in science? SI units are interrelated in such a way that one unit is derived from other units without conversion factors. SI is used in most places around the world, so our use of it allows scientists from disparate regions to use a single standard in communicating scientific data […]
Is the reaction between magnesium and hydrochloric acid exothermic?
Is the reaction between magnesium and hydrochloric acid exothermic? The reaction between magnesium metal and hydrochloric acid is exothermic, because it released energy in the form of heat (increase of temperature). The energy required to break the bonds of the reactants were more than the energy required to make the new bonds of the products. […]
Do scientists need to write well?
Do scientists need to write well? Thus the scientist must not only “do” science but must “write” science.

What are the two types of elements that make up an ionic compound?
What are the two types of elements that make up an ionic compound? Ionic Bonds An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. Which […]
What is the difference between TE and TM waves?
What is the difference between TE and TM waves? The difference between TE and TM mode is that TE stands for transverse electric mode while TM stands for transverse magnetic mode. TE mode is also known as H mode as there is only a magnetic field along the direction of propagation. Why TEM wave is […]
