If the current I through a resistor is increased by 100% (assume that temperature remains unchanged), the increase in power dissipated will be

(a) Law of conservation of mass  (b) Polyatomic ion  (c) (3 × atomic mass of Ca) + (2 × atomic mass of phosphorus) + (8 × atomic mass of oxygen) = 310  (d)...

(a) Increase in temperature of water

Resistance of the resistor, R = 100 Ω Supply voltage, V = 220 V Frequency, ν = 50 Hz (a) The rms value of current in the circuit is given as l =V/R =220/100=2.20A (b)...

(c) Current assets are those assets which get converted in cash or cash equivalents within a short span of time and provide liquidity to a business. For financing the current assets...

Current remains constant.

When a metallic conductor is heated, the atoms in the metal vibrate with greater amplitude and frequency. Due to increase in temperature, the thermal velocities of free electrons also increases....

(d) Frequency. EXPLANATION:  When the sound wave is refracted from air to water, due to the change in B and ρ the velocity of the sound V changes. Hence the options (a)...

(b) The focal length of a converging lens. (d) The focal length of a diverging lens.

It's because n-factor in 2H2O is "4" 2H2O→O2+4H + 4e Since the n factor if 4 We took 4 there... I hope u have understood the answer
