State 7 fundamental quantity with their SI units ? ​

Answer»

The VALUE of a physical quantity is usually expressed as the product of a NUMBER and a unit. The unit represents a specific example or prototype of the quantity concerned, which is used as a point of reference. The number represents the ratio of the value of the quantity to the unit. In the case of the kilogram, the prototype is a platinum-iridium cylinder held under TIGHTLY CONTROLLED conditions in a vault at the BIPM, although there are a number of IDENTICAL copies kept under identical conditions located throughout the world. A quantity of two kilograms (2 kg) would have exactly twice the mass of the prototype or one of its copies. There are seven base quantities used in the International System of Units. The seven base quantities and their corresponding units are: length (metre) mass (kilogram) time (second) electric current (ampere) thermodynamic temperature (kelvin) amount of substance (mole) luminous intensity (candela)Explanation:

Electric charges - 1000 uC are placed at points A and B respectively at a distance of 2 m from each other.Calculate the electric fields at (i) mid-point of the lineto the lineAB and (ii) a point at equal distances of 4 m from eachcharge​

Answer»

Here the point at which the electric field has to be found FORMS an ISOSCELES triangle with both the charges each 4m from the equatorial point .This point lies on the equatorial point.E = k*2aq/(r2 +a2)3Here r = altitude = √15a = 1 m = 1/2 the distance from each charge.K = 9*10^92a = 2mSubstituting the values in the above formula we GET,E = 2.8 *10^5N/C.For being 4m away from each charge ..it MUST form an isosceles triangle.the charge will be on the equatorial line of the dipole.the formula will be -k4aq/r*r*r

A thin lens made of glass of refractive index 5 has a front surface +11D power and back surface -6D. If thin lens is submerged in a liquid of refractive index 1.6 , the resulting power of the lens is please answer with explanation​

Answer»

The lens maker formula reads as follows .1/f=[(n2-n1)/n1][(1/R1)-(1/R2)]. Here,f is focal length of thin lens.n2 is absolute refractive index of material of lens.n1 is refractive index of medium SURROUNDING the lens.R1 is radius of CURVATURE of the first surface of lens.(on which the RAY is incident ).R2 is radius of curvature of the second surface from where ray leaves the lens.In Cartesian SIGN convention ,R1=15 cm, R2=-15 cm.Also,n1=1.65 and n2=1.6 (GIVEN).Substituting all these values in the above mentioned lens maker formula, we have,(1/f)=(1.6–1.65)/(1.65)[(1/15)+(1/15)]=-[(0.05)/(1.65)](2/15)=-0.1/(1.65X15)Therefore, f=-1.65X150=-247.5~-250cmExplanation:Hope it is helpful for you please make me a brain list
