Two bodies of masses m1 and m2
are connected by a light string going
over a smooth light pulley at the end of an incline. The mass m1
lies on
the incline and m2
hangs vertically. The system is at rest; Find the angle
of incline and the force exerted by the incline on the body of mass m1
.

What component of earth’s atmosphere exists entirely as a result of photosynthesis?

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
