Work = force × distance
21000 = force × 12m
we need to rearrange this equation because force isn't on the right side of the equation and it becomes
force = 2100 ÷ 12m
force = 175N
Solubility - is how much solute will dissolve in the solvent (so that would be a measure of how much salt (solute) would dissolve in the water (solvent) making up a solution)
Answer:
It is also called law of Malus,the law states that the intensity of a beam of plane-polarized light after passing through a rotatable polarizer varies as square of the cosine of the angle through which the polarizer is rotated from the position that gives maximum intensity expand.
Before u can know it u have to understand it, so go through it over and over again and u will get it.
Answer:
The current on the water layer = 1.64×10^-3A
Explanation:
Let's assume that the radius given for the string originates from the centre of the string. The equation for determining the current in the water layer is given by:
I = V × pi[(Rwater + Rstring)^2 - (Rstring)^2/ ( Resitivity × L)
I =[ 166×10^6 ×3.142[(0.519×10^-4) + (2.15×10^-3])^2 - ( 2.15×10^-3)^2] / ( 183 × 831)
I =[ 521572000(4.848×10^6)- 4.623×10^-6]/ 154566
I = 252.83 -(4.623×10^-6)/ 154566
I = 252.83/154566
I = 1.64× 10^-3A
