There is no LOSS of ENERGY during INTERFERENCE. It is SIMPLY REDISTRIBUTED.

This man has a TURBAN on his HEAD because, as you can see in the picture, he has to carry a lot of luggages. And as he probably doesn't have enough arm strength to carry all of the luggages by hand, then a few of his suitcases are on TOP of his head. So to PREVENT his head from hurting, he WEARS this red turban.This is what I think the correct answer is, and if it is, and I helped you get the answer correct, then I'm glad that I helped!! Hopefully I did! : )Explanation:

placement of the point  P if the WHEEL rolls  FORWARD through half a revolution is 5√(π²+4)Explanation:Given the RADIUS of the wheel R = 5mAs shown in the figure, the point P will reach at P'after half a revolutionThe distance covered on the ground by the wheel due to rolling after half a revolution will be πRThe displacement of the point P will be PP'In right angled triangle PQP'Putting the value of R = 5M, we get the displacement of point PHope this answer is helpful.Know More:Q: What is the displacement of the point of a wheel initially in contact with the ground when the wheel rolls forward a revolution? take the radius of the wheel as R and the x-axis as the forward direction? along with steps.Click Here: brainly.in/question/1295962Q.

Because Positive Ion - OCCURS when an atom LOSES an ELECTRON (negative charge) it has more protons than ELECTRONS.

WAVELENGTH IN GLASS = WAVELENGTH IN AIR / REFRACTIVE INDEX OF GLASS             =6000*10^-10/1.5=4000*10^-10        OPTION  2Explanation:

UYGENHUYGENthe idea of secondary wavelet is first given by HUYGEN . Explanation: ACCORDING to Huygens' principle, every point on a given wavefront can be CONSIDERED to be a SOURCE of secondary wavelets which are spherical spreading out in the forward DIRECTION at the same speed of light.mark as brillienst answer

The light reflected is perfectly POLARISED. The tangeny of POLARIZING light is EQUAL to refractive index. Hence, when unpolarised light beam is incident from air onto glass (N = 1.5) at the POLARISING angle the reflected beam is polarised 100 percent.

a is the ANSWER to the QUESTION.

tion:We will only USE the first quadrant, which is bordered by the X- and the y-AXIS. The point where the two lines MEET is called the origin (0,0). These two axis represent two variables and each point on the graph has therefore two “coordinates”.

Density is the ratio between the MASS and the volume of a body. Relative density, on the other HAND, is the ratio between the density of an object (SUBSTANCE) and the density of some other reference object (substance) at some given TEMPERATURE. Density is measured in, while relative density is dimensionless.

tion:as per the QUESTION We will only use the first quadrant, which is BORDERED by the x- and the y-axis. The point where the two lines meet is CALLED the origin (0,0). These two axis represent two variables and each point on the graph has therefore two “COORDINATES”.your answer

a)0.5m/s² and b) 1500mExplanation:The acceleration is v-u/t. Therefore,10-5/10=0.5m/s² and the DISTANCE in 50s is equal to TIME ×speed , hence 50×30 gives 1500 m . You may see the graph from picture which I have uploaded

tion:What is the gravitation of two gold spheres of radius 20cm and 40 cm respectively, each separated by 170 m from their centre and density of both gold is 19.3G/cm^3?On-premise and cloud DATA protection in times of uncertainty.We know that in Newtonian mechanics, F = Gm1m2/r^2Where F is the attractive force between 2 masses, m1 and M2, r is the DISTANCE between the centres of the masses and G is the universal gravitation constant, which is 6.674x10^-11 Nm^2/kg^2IF, however, one MASS is much greater than the other, we can writeg = GM/r^2 where M is the larger mass (and we call g “gravity”, or properly “the acceleration due to gravity”; g has units of m/s^2)In this case, we have a gold sphere of R = 20cm, so Vol = 4/3 π R^3 = 33510.32 cm^3, and the mass of this sphere is m1 = 33510.32(19.3)/1000 = 646.75kg. Similarly, we have a gold sphere of R = 40cm, so vol = 4/3 π R^3 = 268082.57cm^3 and the mass of this sphere is m2 = 268082.57(19.3)/1000 = 5174.0kg.Then the gravitational attractive force F = Gm1m2/r^2F = (6.674x10^-11)(646.75)(5174.0)/170^2 = 772.77x10^-11F = 7.73x10^-9 NI hope it HELPS you mate.
