37. A parallel plate capacitor with oil(dielectric constant K=2) between the
plates has a capacitance C if the oil is
removed the capacitance of the capacitor
becomes *
​

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000
