How do you find the speed of light in cooking oil? c – speed of light in vacuum; n2 – refractive index for the oil. Thus the total value of the speed of light penetrated through the glass and the oil, can be calculated according to the formula below: v3 = c/(n1*n2) = 299792/(1.5*1.33) = […]
Why are pendulums not SHM?
Why are pendulums not SHM? Any pendulum undergoes simple harmonic motion when the amplitude of oscillation is small. The pendulum still oscillates, but the motion is no longer simple harmonic motion because the angular acceleration is not proportional to the negative of the angular displacement. What is the maximum displacement of a body in simple […]

Does higher frequency mean better sound?
Does higher frequency mean better sound? The answer to this question is clearly no. You might suspect, that the higher the frequency, the louder we perceive a noise, but frequency does not tell us how loud a sound is. Intensity or loudness is the amount of energy of a vibration and is measured in decibels […]
What color dissipates heat the fastest?
What color dissipates heat the fastest? black What material stays cool in the heat? Since then, they and other researchers have made a host of materials, including films, spray paints and treated wood, that stay cool in the heat. These materials all rely on enhancing a natural heat-shedding effect known as passive radiative cooling. What […]

When water, H2 O, is in liquid form, it can be heated to a boil. Is Steam a chemical reaction? A physical reaction causes the matter to shift shape or […]
What are the two functions of the muscular system?
What are the two functions of the muscular system? The main function of the muscular system is movement. Muscles are the only tissue in the body that has the ability to contract and therefore move the other parts of the body. Related to the function of movement is the muscular system’s second function: the maintenance […]
