placed on top of a car should be advised to fasten with ROPE because while the car collects SPEED and is moving regularly, the luggage will move BACKWARDS. For EXAMPLE, if the car moves FORWARD, the luggage will move backward, If the car moves backward, the luggage moves forward. By bounding the luggage to the car with rope, it restrains it and keeps it secure while the car is active.

common observation that water flows from a place at a higher level to a place at a lower level or potential irrespective of amount of water at the two LEVELS . Heat flows from a body at a higher temperature to a body at a lower temperature irrespective of the amount of heat contained by the two BODIES . Similarly electric charges move from one POINT to another if there exist a difference in electric potential irrespective of concentration of charges at the two points . Thus electric potential determines the direction of flow of electric CURRENT . Charge flows from a body at a higher potential to body at a lower potential . By convention a positively charged body is always at a higher potential as compared to negatively charged body . If positive charges like protons or positive ions are free to move they would move from higher potential point to lower potential point. Usually the movement of charges implies movement of electrons. It is clear that electrons will move from lower potential to higher potential. This constitutes electronic current. Since the convention is that flow is always from higher to lower level, the conventional current is taken opposite to the electronic current. It should be remembered that conventional current implies that movement of positive charges whereas electronic current is movement of electrons. NOTE : Conventional current was given much earlier when electron flow was unknown.And movement of electronic current is a MODERN concept.

le of PPG. PPG makes uses of low-intensity INFRARED (IR) LIGHT. When light travels through biological tissues it is absorbed by BONES, skin pigments and both venous and arterial blood. ... Even small changes in blood volume can be detected using thismethod, THOUGH it cannot be used to quantify the amount of blood.

A negative exponent just means that the BASE is on the wrong side of the fraction line, so you need to flip the base to the other side. For instance, "x–2" (pronounced as "ecks to the minus two") just means "x2, but underneath, as in 1 x 2 \frac {1}{x^2} x21 ".Ans(2)-The power of a lens is the measure of its ability to converge or diverge a PARALLEL beam of LIGHT on refraction through it .Negative sign for Concave lens and Positive sign for CONVEX lens. The S.I.unit of power is dioptre

riend...............Here is your answer...............The simple answer to "why is the PRESSURE inside a soap bubble HIGHER than outside," is that a higher pressure than the local ATMOSPHERE is required to make the bubble in the first PLACE! This requirement COMES from the need to counterbalance the surface tension force.

d UR ans is hereBecause magnetising current of SINGLE phase transformer is very less approx. 2 to 6 percent of full load current hence we generally leakage flux depends of load current…

tical MEMBERS of the frame are CALLED stiles while the HORIZONTAL members  are known as rails.

y u/UMAX = 1- (2y/h)^2 where h is the distance separating the plates and the origin is placed MIDWAY between the plates. Consider a FLOW of water at 15 C, with umax = 0.30m / sec and h = 0.50mm. Calculate the SHEAR stress on the upper PLATE and give its direction.

coz when flux is CHANGED then magnetic field lines intersect and so the CURRENT is INDUCED

mes approximately 30-40 % fake materials added in FOOD . for ex. vegetable oil in name of ghee. in cold DRINK CAFFEINE is mixed which causes hypnia and headache. phosphoric acid is mixed it can melt a iron also. glaicol acid is mixed ,it prevent water to freeze in zero degree also

gth=SPEED/frequencyBut speed = VELOCITY.: 500/20=25.

e of OBSTACLE or APERTURE should be of same ORDER as the wavelength of LIGHT.

t IMPORTANT part about this is not only that OBJECTS pull on each other, but that two objects attract each other with a force that is proportional to the PRODUCT of their masses and INVERSELY proportional to the square of the distance between them. This is known as Newton's law of universal gravitation.

eading egreg's comment, CHANGING from \SQRT[3]{x} to \root 3 \of{x}, to indicate using plain TeX, not LaTeXConsider $$\sqrt{x}$$ VS $$\root 3 \of{x}$$.The latter has a 'root' of 3.How do we typeset this?On page 443 of the TeX Book, rule 11, it describes typesetting the radical atom: \radcal and \sqrt. However, it only describes "root-less" types, like \sqrt{x}, and not the ones with a root, like \root 3 \of{x}

f GRAVITY acting on a body of mass m on the earth surface = F = GMm/R^2 ____________ (1)Where R is the radius of the earth (considering it a homogenous sphere)and M here is the total mass of earth concentrated at its centre. G is the gravitational constant.Now, from Newton’s 2ND Law of Motion,F = mg.___________________(2)Just to recapitulate, as a body falls downwards it is continuously ACTED upon by a force of gravity. The body thus possesses an acceleration, called Acceleration Due to gravity(g).

iation is INCREASED by the factor of 81/256. We can SOLVE this from Stephen BOLTZMAN law of radiation, which is, P is directly proportional to T^4. Where T is in kelvin

ctron REVOLVE around the nucleus in fixed orbit of definite ENERGY in which it doesn't RADIATE energy. these NON radiating orbit are called stationary ORBITS

..... it's ALSO DECIDE the COLOUR of OBJECT

ns AROUND a nucleus are not a classical problem but CONSERVATION of energy holds also in the QUANTUM states. The electron around a nucleus is in a quantized energy level and can change it only if an external interaction intervenes... Therefore an electron in its ground state cannot EMIT energy.

Find the MAXIMUM Kinetic ENERGY of a Photoelectron ... This value is the maximum possible kinetic energy of the photoelectron. The equation, which Einstein DETERMINED, says (electron's maximum kinetic energy) = (energy of the incident LIGHT energy packet) MINUS (the work function). For the example, the electron's maximum kinetic energy is: 2.99 eV - 2.75 eV = 0.24 eV.

.83 m/s²Step by step explanationGiven that,WEIGHT of the boy on the SURFACE of earth = 400Nweight of the boy on a mountain PEAK = 360NFormula to useW = mgAs we know that MASS remain CONSTANT irrespective of the place of an object and acceleration due to gravity on the earth surface is 9.81 m/s²So,1)400 = m(9.81)m = 40.77 kg2)360 = (40.77)gg = 360/40.77g = 8.83 m/s² on the mountain peak.

The correct answer is "WHITE".Explanation:Dispersion is the phenomenon in which the white light splits into the seven different colors.When the white light is passed through the prism then the light gets split into seven band of colors. The refraction phenomenon occurs when the light passes through the prism due to the change in the speed of the light while TRAVELLING from one medium to another.Red COLOR is maximum DEVIATED. Violet is the least deviated. Red has longer wavelength while violet has shorter wavelength.Therefore, Dispersion of white color is minimum in visible range of light
