Two teenagers push on heavy create. Dion pushes with force of 185N, east and Joan is pushing with a 195N [North60°West] a. draw a free body diagram.
b. what is the resultant/net force on the create?

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?

A1.5m wire carries a 2 a current when a potential difference of 52 v is applied. what is the resistance of the wire?

You can melt ice by applying pressure because the solid/liquid line has a slope.
