For which one of the following pair of projectile angle the horizontal range will be same (Explain in detail please) a)45,55 b)27,63 C)58,64 d)33,85

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

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

not moving. pos accel,
