Ple 8.2: The length of a straight thin wire is 2 m. It is uniformly charged with a positive charge of 3µC. Calculate (i) the charge density of the wire (ii) the electric intensity due to the wire at a point 1.5 m away from the center of the wire

Answer»

Given Info: The length of a straight thinwire is 2m. it is uniformly charged and its charge density becomes 1.5 x 10-6 C/m.To find: the electric FIELD intensity due to the wire at a point 1.5 m away from the centre of the wire is...Solution: charge density of wire, λ = 1.5 x 10-° C/mwe can apply Coulomb's LAW only for point charge, so here we have to first take an elementary length of wire to MAKE it valid for coulomb's law.so CUT an element dx, x distance from the point of observation. [ see figure] now charge on element, dq = Xdx electric field density due to element, dE = KdQ/x²= Kλdx/x2= KXJdx/x²= KX [-1/x]upper LIMIT= (1 + d)lower limit = d= KA [1/d - 1/(1+ d)]= KXI/d(I + d)now putting, K = 9 x 10^9 Nm²/C², λ = 1.5 x 10-6 C/m, d = 0.5 m and I = 2m= (9 x 10^9 x 1.5 x 10^-6 x 2)/(0.5 x 2.5)= 12 x 10³/(1.25)= 9600 N/CTherefore the electric field intensity due to wire at a point 1.5m away from the centre of wire is 9600 N/C.pls mark me as brainliest and follow me

One of the property of biogas?can you pls answer these question​

Answer»

Biogas typically refers to a GAS produced by the biological breakdown of organic MATTER in the absence of oxygen. Organic WASTE such as dead PLANT and animal material, animal dung, and kitchen waste can be converted into a gaseous fuel called biogas. Biogas originates from BIOGENIC material, for example through anerobic digestion, and is a type of biofuel.

I know that the gravity of the moon causes ocean tides on earth. How does centrifugal force cause the far-side bulge? please give answer in short or easy word.​

Answer»

The tidal bulge on the far side of the earth is not caused by centrifugal force. It is caused by the exact same thing the near-side bulge is caused by: the moon's gravity. Furthermore, tidal effects are not caused by the overall strength of gravity like planetary orbits are. Rather, tidal effects are instead caused by GRAVITATIONAL gradients, which are differences in gravity from one point on earth to the next. These differences in the gravitational field arise from the fact that the moon's gravity spreads out into SPACE radially in all directions and weakens with distance. In fat, both the sun's and the moon's gravity add together to create the tidal bulges. The bulge on the near side is not caused by the water being attracted to the moon by its overall gravitational force. Instead, both tidal bulges are the response of ocean water to the gravitational gradient of the sun and the earth, as explained in the textbook "Planetary SCIENCES" by Imke de Pater and Jack J. Lissauer. In the gravitational-gradient effect, not all points on the earth are attracted to the moon. If we ignore the sun for a moment, the ocean water is attracted towards the axis of the earth that points to the moon, and then out along the axis as shown in the picture. As a result, the ocean squashes into a football shape. The ocean's tidal bulges are like taking a spherical balloon and squeezing on the sides until the top and bottom bulge out. Even if the earth stopped spinning, there would still be two tidal bulges. The spinning of earth does lead to centrifugal-force-caused bulging, known as EQUATORIAL bulging, but it is a DIFFERENT effect from tidal bulging.

Distinguish between progressive waveves statuouary waves

Answer»

tion:STATIONARY WAVES are STILL, they do not travel in a medium. PROGRESSIVE waves travel in the medium in different phases.

Q. If the amplitude of the pendulum is increased how does it affect the time period of the pendulum?

Answer»

time PERIOD increasesExplanation:In a simple pendulum, which can be modeled as a point mass at the end of a string of NEGLIGIBLE mass and a given length, the amplitude is NORMALLY only a few degrees. When the amplitude is this small, it does not affect the periodof the pendulum. As the amplitudeof the pendulum increases, the period increaseshope it helpsmark as BRAINLIESTTHANKS plz
