Physics Section A system absorbs 80 J of heat energy while doing 100 J of external work. What is the change in the internal energy of the body? -100 J -20 J +80 J +100 J The SI unit of electrical resistance is: Ampere Volt Farad Ohm Progressive waves of frequency 300 Hz are superimposed to produce a system of stationary waves with adjacent nodes 1.5m apart. What is the speed of the progressive waves? 100 ms -1 200 ms -1 450 ms -1 900 ms -1 Two thin lenses have focal lengths of 20cm and -40cm. the focal length of the combination lens will be: +20 cm +40 cm -20 cm -40 cm The distance between the optical center of the lens and its principal focus is known as the: aperture pole focal length none of the above When the light from two lamps falls on a screen, no inte...
