Explain some simple techniques used ton detect adulterants at home .
(a) Milk
(b) Honey
( c) Suger
(d) Cuffee powered
( e) Food Grains

Text Solution

Verified by Experts

(a) Milk:
Place a drop of milk on a polished surface . Pure milk flows slowly , leaving a trail behind . Milk with water will flow fast , without leaving a trail .
(b) Honey
Dip a cotton wick in honey and light it with a match stick . Pure Honey burns , but adulterated honey gives a cracking sound .
( c ) Sugar:
Dissolve sugar . If chalk powder is added as an adulterant , it will settle down .
(d) Coffee Powder :
Sprinkle a few pinches of Coffee powder in a glass of water . Coffee powder floats . If it is adulterated with Tamarind powder , it settles down .
(e) Food Grains :
Food grains are mixed with stones , sand grit , marble ect . They are removed by Sorting hand picking , and washing .

Figure shows a metal rod PQ resting on the smooth rails AB and positioned between the poles of a permanent magnet. The rails, the rod and the magnetic field are in three mutually perpendicular directions. A galvonometer G connects the rails through a switch K. Length of rod = 15 cm, B = 0.50 T, resistance of the closed loop containing the rod = 9.0mOmega . Assume the field to be uniform. a. Suppose K is open and the rod is moved with a speed of 12cms^(-1) in the direction shown. Give the polarity and magnitude of the induced emf. b. Is there an excess charge built up at the ends of the rods when K is open? What if K is closed? c. With K open and the rod moving uniformly, there is no net force on the electrons in the rod PQ eventhough they do experience magnetic force due to the motion of the rod. Explain. d. What is the retarding force on the rod when K is closed? e. How much power is required (by an external agent) to keep the rod moving at the same speed (=12cms^(-1)) when K is closed? How much power is required when K is open? f. How much power is dissipated as heat in the closed circuit? What is the source of this power? g. What is the induced emf in the moving rod if the magnetic field is parallel to the rails instead of being perpendicular?
