“It’s also natural,” Grandfather said. “An unstable nucleus breaks down – – releasing energy.”
Anya used a across the bulb (measuring potential difference ) and an ammeter in series (measuring current ). She adjusted a knob (a rheostat ), which changed the resistance . icse class 10 physics
They pushed. The trolley moved slowly. Anya realized she was doing (force × displacement). When they paused midway, the trolley had potential energy because of its height. When it rolled down a small dip, that energy converted to kinetic energy . “It’s also natural,” Grandfather said
