Construct a quadrilateral ABCD, given that AB = 4.5 cm, BC = 5.2 cm,

CD=4.8 cm and diagonals AC = 5 cm and BD=5.4 cm.

Explanation:

The capacitor is a component which has the ability or “capacity” to store energy in the form of an electrical charge producing a potential difference (Static Voltage) across its plates, much like a small rechargeable batteryThere are many different kinds of capacitors available from very small capacitor beads used in resonance circuits to large power factor correction capacitors, but they all do the same thing, they store charge.how voltage charge capacity energy and electric field changes when dielectric is introduced between the plates of capacitor 1)with battery connected2) without batteryMonerans are unicellular, prokaryotic organisms found in a moist environment and lack a true nucleuonera break down the dead matter and food in our digestive system. They can also prepare their own food, but bacteria feed on dead matter.

>>Two rods of the same length, have radii

Question

Two rods of the same length, have radii in the ratio 3:4. Their densities are respectively 8000 and 9000kg/m

3

. Their specific heats are in the ratio of 2:3.When the same amount of heat is supplied to both,the changes in their lengths are in the ratio. (If their linear coefficients are in the ratio 5:6)

Correct option is B)

Heat supplied: Q=msΔθ where m is the mass of the rod, , s is the specific heat of the rod and Δθ is the temp difference.

Δl=lαΔθ where α is the co-efficient of linear expansion and l is the length before being heated.
