How do you write a good results section of a lab report? In addition to the measurements taken during the experiment, the results section should include any observations that were made during the experiment. Unexpected phenomena may affect the results in ways that are not known by the author of the lab report but may […]
What can stop friction?
What can stop friction? There are several ways to reduce friction: The use of bearing surfaces that are themselves sacrificial, such as low shear materials, of which lead/copper journal bearings are an example. Replace sliding friction with rolling element friction, such as with the use of rolling element bearings. What happens if we don’t reduce […]

Which kind of lenses are in a light microscope?
Which kind of lenses are in a light microscope? Principles. The light microscope is an instrument for visualizing fine detail of an object. It does this by creating a magnified image through the use of a series of glass lenses, which first focus a beam of light onto or through an object, and convex objective […]
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 […]
What happens when light passes through Coloured glass?
What happens when light passes through Coloured glass? Colored glass is a filter that are largely transparent, but absorb some frequencies of light (some colors). White light goes in and, as it passes through, the glass absorbs some of the light at specific frequencies. Thicker glass will be darker because the light has to travel […]
What problems do you face when you connect two bulbs in series?
What problems do you face when you connect two bulbs in series? (a) In series circuit the bulbs will glow dimly. It is because magnitude of current decreases in series circuit. What would happen if you connect multiple light bulbs in series to a source? If light bulbs are connected in series to a voltage […]
How do neurons communicate with one another?
How do neurons communicate with one another? Neurons talk to each other using special chemicals called neurotransmitters. Neurotransmitters are like chemical words, sending “messages” from one neuron to another. There are many different sorts of neurotransmitters: some stimulate neurons, making them more active; others inhibit them, making them less active. How do neurons fire? The […]
Which one is the strongest bond?
Which one is the strongest bond? Cl−F bond is strongest among all. What is most likely to bond with fluorine? lithium What happens when two fluorine atoms bond? In Figure 2, two fluorine atoms can each fill their valence orbitals with eight electrons if they approach each other to share their single electrons. The two […]
What do S and P waves have in common?
What do S and P waves have in common? P (Primary) and S (Secondary) Waves are Body Waves often associated with Seismic Waves as in Earthquakes. Both Body Waves and Surfaces waves comprise an earthquake, but the body waves arrive first. Primary are first, And Secondary are, well, second of course. What type of rhythm […]
