What do you understand by the terms (i) linear expansion (ii) superficial expansion (iii) cubical expansion?Can anyone please send me this in theory |
|
Answer» Answer: (i) Linear expansion means change in one DIMENSION (length) as opposed to change in VOLUME (volumetric expansion). To a first approximation, the change in length measurements of an object due to thermal expansion is related to temperature change by a coefficient of linear thermal expansion (CLTE). (ii) Superficial expansion is defined as the increase in surface AREA of the solid on heating. If you consider at 00C area of a solid is A0 then its area at t0c is given by: A0(l+βt). Unit of β is 0C-1 or K-1. Where β is known as the coefficient of superficial expansion. (iii) Cubical expansion means that the volume of a material changes by some fixed fractional AMOUNT. |

. The nature of oxides helps to identito prove this and record the obse |
|
Answer» The nature of oxides helps to identify the metals and non metals conduct an EXPERIMENT to prove this and record the observation. Explanation: Take an iron rod. place it in the external environment for about a week. then we observe that the iron rod would get rusted. note your observations. later, take a plastic bottle or the items made by plastic and place the plastic in the external environment for some days. now you observe that the plastic does not gets rusted. by this experiment, we can state that iron rod is a metal and plastic is a non ,etal.oxygen gets deposited on the layer of a metal and they forms as oxides and they finally REACT with that particular metal and gets rusted, thus forms BROWNISH COLOUR on the top of the metal. |

playing middle C on a piano keyboard produces a sound with frequency 256 Hz. What is its time period |
|
Answer» Answer: Playing MIDDLE C on the piano keyboard produces a sound with a frequency of 256 Hz. Assuming the speed of sound in air is 345 m/s, determine the wavelength of the sound corresponding to the note of middle C. Explanation: V = fλ Now plug in your numbers to find λ1.35 METERS (rounded) Let λ = wavelength. Use v = f • λ where v = 345 m/s and f = 256 Hz. Rearrange the equation to the form of λ = v / f. Substitute and SOLVE. |

What is force multiplier machines |
|
Answer» Answer: A lever is an example of a simple machine. Ramps and pulleys are simple MACHINES that ACT as force multipliers. If a machine makes it possible to lift or move a LOAD using a smaller force, the force has to move through a greater distance. The total amount of energy NEEDED is the same. |

Match the columns.1. Three fundamental physical quantities2. SI unit of time3. Rotational motion4. Hand span5. A length which is (1/1000)th part of a metre6. Rectilinear motion7. A length equal to 10,000 m8. Millimetre(a) small unit of measuring length(b) length, mass, time(c) straight line motion(d) motion about an axis(e) improper unit of measurement(f) 10 km(g) seconds(h) millimetre |
|
Answer» Answer: 1. physical quantities are taken as fundamental is somewhat arbitrary, but the three usually selected are length, time, and mass. 2. SI unit of time (second) 3. Purely rotational motion occurs if every particle in the body moves in a circle about a single line. This line is called the AXIS of rotation. Then the radius vectors from the axis to all particles UNDERGO the same angular displacement at the same time. The axis of rotation need not GO through the body. 4. Hand span is a measure of distance from the tip of the thumb to the tip of the little finger with the hand fully extended. Each student PLACES his or her dominant hand on the edge of a piece of paper with the hand fully extended. The student should make a mark at the tip of the thumb and the tip of the little finger. 5. millimeter 6. a linear motion in which the direction of the VELOCITY remains constant and the path is a straight line. 7. 10 kilometers 8 question am not sure |
